Translators' note

Wb are pleassd to offer this fourth volume of the series Pilze der Scrrweiz to readers oI English. Volume 4 is a continuation of the Agaricales, which were begun with volume 3, and includes mostly pink-, brown-, and black-spored species. lnterpreting the color of spore prints is essential as a first step in identifying mushrooms. However, colors are subjective and difficuft to describe so that beginners in particular can understand iust what e. g. .umber-brown" means, ln response to this problem, the authors have developed an innovalive and elegant means of presenting the color of spore prints objectively. They have done this by scanning the spore prints into a computer and codifying the colors so that a printing company can duplicate them on the printed page. (See "Methods" for further details.) As far as we know this is the first time this has been done. This new feature of Vol. 4 will be a welcomed and helpful addition to an already very useful (and beautiful) format.

Again, many rare and unusual species from rare and unusual habitats are included. These collections are a testimonial to the diligence of the authors and other collectors. They are al-

so important as documents of the fungal llora of declining habitats, such as wet and poor meadows and peat bogs, as discussed by Dr. Senn-lrlst in her Preface. Like her, we hope that this series will make surveys of the fungal flora of other parts ofthe world morefeasible by lightening the task o, identification. Our relerences remain the same as for Volume 3. As in the previous volumes, the Glossary is a compilation oJ a translation of the authors' glossary and our own definitions of technical words which we used in the English version. Glosses of the words used also in Vol. 3 are not repeated here. Trinidad, California, August 1995 Mrginia L. Waters James F.

Preface

ln 1992 the widely noticed Earth Summit took place in Rio. lt

concerned the establishment

of

internationally applicable and accepted rules ,or the protection of our environment. A result of this mammoth congress is the so-called Rio Convention, which contains a consensus about biological diversity, and which was signed by Switzerland along with many other countries. An important article is quoted as follows in the original text: Art. 6. General lvleasures for Conservation and Sustainable Use Each Contracting Party shall, in accordance with its particular conditions and capabilities, develop national strategies, plans, or programmes for the conservation and sustainable use of biological diversity.... Conservation and sustainable use mean utilizing in a manner which does not lead to long-term decline in biological diversity, so that its potential to fullill the needs and wishes of contemporary and future generations is maintained.

But conservation also means that exact and reliable facts must be known about present diversity. This is the thrust of an appeal launched by several organismally oriented American societies in accord at the Eafth Summit in Rio: the Syste-

matics Agenda 2000 is a stirring challenge to discover by combined efforts the diversity of species of this Earth in all groups of organisms. First, the newly discovered species should be precisely described as quickly as possible. Second, they should be classirled, on an evolutionary-biological basis as far as possible. Third, the available knowledge should be maintained in generally accessible data banks. Finally, possible ways of sustainable uiilization should be pointed out. The first step, the discovery includes far more than merely a

correct and valid description in some scientific journal or other. Good information on systematic relationship and ecology is also required. Only when we understand in each case why we on the one hand separate similar species, why we on the other hand assign relatively dissimilar-appearing species to e. g. the same genus, do we begin to comprehend the natural laws of biology. We can preserve this diversity, once we have recognized it, only if we know not only its unique biological characteristics

but also its habitat requirements and its earlier and current distribution. Here the volumes of "Fungi of Switzerland. iill an important gap. The great success of the first three volumes clearly indicates how important splendid visual documenta-

tion, whether color plates or line drawings o, anatomical details, along with descriptions of original observations, or as in the present case a combination of all of these, are for a confirmable understanding of the demonstrated diversity of species. We are indebted to non-specialists for this! Only if it is possible to determine species without using the specialized literature will a larger circle of amateur mycologists concern themselves with questions of distribution and ecology. The higher fungi with their short-lived fruiting bodies are just such a group of organisms in which the astonishing diversity of the native fungal flora is scarcely known beyond a small

circle of specialists. Only good documentation carried out over several years can show us the richness of species which exists, because the fleshy fruiting bodies of gilled fungi are not only very ephemeral but often do not appear every year. The present volume contains several examplss of species which easily escape the notice o, the inexperienced, such as the species-rich geneta Entoloma, Coprinus, ot Psawrella. Entoloma in patlicular thanks to an intensive taxonomic investigation during the last ten years shows on careful examination a truly amazing richness o, species. lvlany members of this genus are found primarily in nutrient-poor meadows and pastures. The authors have succeeded in docu-

-

-

menting species from these habitats whose ranges have decreased very greatly over the last 30 years, primarily because of modification of their habitat (fertilization!). For certain species of poor meadows, such as Entoloma bloxamii, subalpine and alpine meadows and pastures have become declining habitats. The effects ot eutrophication of our environment can be seen indirectly in this fourth volume, more than in any of the former volumes. While on one hand species of threatened biotopes such as poor meadows and rloodplain for€sts could be found and documented by deliberate searching, on the other hand this volume also illustrates species which profit from the increase in eutrophic microhabitats, such as compost piles, flower bordsrs with mulches ol wood chips, roadsides, slump cracks, etc. Some o, these species may be neophytes, that is, recent "immigrants". Color photographs of many such species in the families Coprinaceae, Strophariaceae, and Bolbitiaceae are presented here for probably the first time. They show us once again how versatile fungi as a group are in their ecological requirements. lt would definitely be worthwhile to trace this change in the native fungus ,lora more thoroughly. ln the warmer climate of cities, species could already be found today which could probably expand their ranges very quickly during the predicted global warming!

The constant and progressive destruction of the environment strongly awakens in us the longing for beautiful and simple things, for unsullied nature. Esthetically pleasing pictures fall into this category also. Since the first volume of this series,

we have known that the authors do not let us down in our wish. The authors are not afraid to tread new paths. ln this volume they do so with their attempt to record and reproduce the color of the spore print as objectively as possible. For this they chose a method which has succeeded in the printing indu-

stry: the colors are read by a color scanner and translatsd into numbers and entered into a compuier. A suitable pro-

gram analyses the color and normalizes it. An astoundingly rich palette of different spore colors results from the use of this program, Once again in a novel way one particular aspect ofthe diversity of gilled fungi can be documented. Experience will show how well one's own spore prints can be comparcd with their standards, that is, how narrow or broad the variability in the typical color for a species may be.

ana acknowtedsments

It is not only the urge to experience nature as intimately as possible, nor is it only the rich diversity offungi which lures us again and again out into the rield, the forests, pastures, meadows, and moors or up into the alpine dwarf shrub-heaths. lt

is primarily the unquenchable thirst to discover, to experience, and to understand something new, To formulate and document these discoveries this is the motive which for years has caused us to work -on the flora "Fungi of Switzerland", a flora which so far comprises 1833 macrofungi.

Meanwhile it has become increasingly clearer how indispensable the ,lora of a definite region is, if measures for protecting the environment are to be planned. Far from being merely a quantitatively detailed listing of the macromycetes of Switzer-

land, Volumes '1-4, with their color photographs of fungi, macroscopic descriptions, and drawings of microscopic features, provide a ,oundation which significantly lightens the work of identifying fungi. As a logical extension of this concept, in this volume we rely, right at the beginning of the key, upon a table of spore-print colors, which allows speedy segregation oI individual groups of fungi.

It is to be hoped that all ol this could be a spur for as many mycologists as possible, to set themselv€s likewise to the task of doing lloristic studies, for even red lists of endangered species of fungi are possible only if reliable floristic foundations exist.

We would like to express our special thanks to the following women and men from other pans of Switzerland: Mme. J. BONNARD, St. Sulpice VD, Dr. B. SENN-lRLET, Bern, Mrs. M. STBEBEL-FRUEr, Tegerig AG, as well as DR. l. BHUNNER, Birmensdorf ZH, DR. H. CLEMENQON, Lausanne VD, M. FLUCK-HESS, Oberbipp BE, E FRELECHOUX. Dombresson NE, , H. GSELL, Dattwil AG, G.

STAPPUNG, Dottingen AG, J. THIEN, lnnsbruck (Austria), R. WIEDERIN, Mauren (FL), and H. WOLTSCHE, Bern.

All o, them have placed at our disposal interesting collections

of fungi with transparencies. With these the number of species documented could be significantly increased. ln particular, G. LUCCHINI of Tessin sent over 20 collections of linds which we could not have made ourselves. We would like to mention especially J. BACHLER, who has contributed greatly to increasing the abundance ol the groups of fungi presented here, by sending more than 50 collections along with descriptions, microscopic drawings, and transparencies.

We thank F. I/ARTI, Peseux and O. PEHRSON in Naka (Swe-

den) for procuring literature. O. PERSSON has kindly translated the Danish texts into German. We must especially mention the Rijksuniversiteit of Leiden (Holland), which has pla-

ced every desired item oi literature at our disposal without cost. Many thanks.

ln the same manner, we will tackle Volum€ 5,

which deals with

the large family Codinariaceae.

As we did in the previous three volumes, we should again record the help of our colleagues in the Mycological Society ot Lucerne, as well as other mushroom enthusiasts from all ol Switzerland and even from foreign countries, in preparing the present book.

First of all, we thank our colleagues in the Floristics Study P AMBEIN, J. BACHLER, W. KISER, A. LEEB, K. N4UHLEBACH, R. MURNER, F, IVULLER, W. oLDANI, G. RICHOZ, H. SUTTER, H. THOIVI, J. WESPI, M. WYMANN, and A. zwYSSlG. GTOUP,

As in the other three volumes also, G. J. KRIEGLSTEINEB, Durlangen (Germany) has edited and proofread all of the descriptions of fungi. His advice and suggestions have helped us very much in optimizing the writing style and subject matter ot our presentation. For the willingness which he brought to our work, as well as for the considerable amount oI time that he has spent on this editing, he deserves very special thanks.

Dr. H. CLEN4ENoON, Lausanne VD, M. ENDERLE, LeipheimRiedheim (Germany), A. HAUSKNECHT, N4aissau (Austria),

lntroduction

Agaricales Parl2, continuation of Volume 3 ln the present volume we treat a second part ot the Agaricales, the families and genera which are listed in the next page.

Because of recent publications, we have included Phollotha as a subgenus oI Conocybe and placed Kuehneromyces in Pholiota. ln addition, Iubana and Crepidotus, formerly in the family Crepidotaceae, have been placed in separaie families. Iubafla is now in the Strophariaceae and Crepldotus is included in the Cortinariaceae.

Wb have worked up about half of the gilled lungi in this volume

and volume 3 together. Neither volume contains the large family Cortinariaceae or the order Flussulales. These will be covered in one or two additional volumes. While working on this volume, we had to take notice of some changes in systematics. For example, the genera Cystoderma and Squamanita, which were originally placed in the family Agaricaceae, were recently transferred to the Tricholomataceae, which has already been treated in Volume 3. We make allowance for this fact by describing the species of these two

genera in the Agaricaceae, while listing both ,amilies in the Synopsis.

Synopsis of the systematics used ln our systematics, we primarily follow MOSER ('1983), and in

our nomenclature we follow KRIEGLSTEINER (1991) and KREISEL (1987), as well as more recsnt monographs.

Genera represented in this volume by one or more species are printed in boldface. The numbers indicate the first and last species of the particular genus.

Methods of study

The methods of study have been described in detail in volumes 1, 2, and 3. Since they have not been changed significantly in working up the fungi included in this volume, we do not describe them again here. We have used only a few new genus-specific reactions, which we explain below. (See also the Remarks conc€rning the individual genera.)

Since most of the fungi in this volume have distinctly colored spores, we have added a color strip lor each species to show the color of its spore print. How the colors are defined is explained in the section of Spore Prints".

This application was described by Julius SCHAFFEH (1933). To determine the Scheffer reaction, one needs pure aniline or

A lamellar fragment is examined in 3% KOH. ln chrysocystidia the contents (colored bodies) turn yellowish. However, this color reaction is not always very distinct.

The test is done on the pileus. With a pipette or a small glass rod, one draws a line 10-20 mm long on the surface with aniline, then draws another one across it with nitric acid. ln a positive reaction the intersection of the two lines will turn from yellow to orange-yellow to deep orange or fire-red. lf there is

Metachromasia ot the spores in Lepiota s. l. Metachromasia is the property of certain tissues or cells to turn a different color from that of a solution of a dye in which they are placed. This is a method ol microscopic examination which is very helplul in identifying species ol Lepiota. The test is done with a 5% solution of cresyl blue in water. Small pieces of lamellae or spores are laid for a few seconds in a very small drop of cresyl blue on a microscope slide. Then the dye is diluted with a drop of water, a cover slip is placed on it, and the slide is examined under oil immersion.

lf the spores are metachromatic, the endospore turns reddish, while the other parts remain blue. The color change is not always equally intense. The spores ol Leucocoprinus,lot

For every description there is a color sample in the form of a strip on the right-hand page alongside the color photograph of the species. The strip shows the color ol the spore print and also the gradation from a darkor to paler shade ,rom the top to the bottom of the strip. For a few species we lacked a spore print tor our own evaluation of the color. ln these cases we record the fact under the description of the spores (no spore print). Ws also supplement the information on sporecolor taken trom the literature by a code ,or the approximate color.

Common names for the various shades, such as chocolatebrown, tobacco-brown, brown-pink, etc. are extremely imprecise and allow many interpretations. lnlormation on color should therefore be standardized and follow an easy and repeatable system. 13

ln our opinion, the subtractive color system is most suitable.

bers is always CMY As a second example, C5M20Y100 =

This system, which is used in color printing, is called the

-2x.

CMYK system. ln this system the letter C stands ror cyan (a blue-green), M for magenta (a violet-red), Y for yellow, and K for black. B is not used, since this letter is already used for blue in the RGB (red-green-blue) system. These so-called complementary colors are components of the "EURo-skala", that is, they ars colors of ink which when mixed in the proper proportions can reproduce the gntire color scale for color prinring (KUPPERS 1981). For our purposes, we used only the CMY system, that is, a three-color system without black. The mixture of all three o, these colors each at 100% density gives black, while 0% ot each of them gives white. Different proportions ol the pigments can produce an entire color scale with over 5000 colors which can be reproduced again at any time.

Tables of color samples, constructed using this three-color system, are available. They reprcsent the colors resulting from mixtures of the three colors in increments of 5% or 10%. One can compare a specimen with the table and get the corresponding code (KUPPERS op. cit.).

As a practical example, we will give the code for the spore

Visual comparisons can, however, be deceiving. The light used for the comparison and the subjectivity of the person are very important. As a partial solution to this problem, we used a rlatbed color scanner along with a Macintosh computer. With this setup one can digitalize color pictures, i. s. convert them to computer-readable information which then appears on the color monitor as the corresponding picture. lf this is possible with color pictures, then naturally it can be done with spore prints. With a program for processing color pictures, such as "Photoshop", one can analyse a "spore picture". One can probe the individual colors on ihe screen and immediately recognize the percentage composition of the three fundamental colors CMY Although this method eliminates subjectivity, turther problems appear which impair ihe results, such as the color fidelity of

the computer system and the compatibility of the printing company's equipment. Equipment with optimal color processing are exp€nsive and for our purposes impractical. A further problem is the variable thickness o, spore deposits. Thin deposits give somewhat different and paler colors Jrom

Coprinus Some species have spores which are difierently shaped in frontal and lateral views, being usually elliptical in lateral view and lentilorm to mitriform in frontal view. ln these cases, the spore sizes are given in the following order: length x width in lateral view x width in frontal view. For the Q-value, the numbers without parentheses refer to the lateral view, while those in parentheses refer to the lrontal view. Since the formula for calculating the volume (Vm) is based on a rotational ellipse, the volume could not be obtained for these spores. We there,ore generally dispense with the volume fot Copinus.

Phase-contrast

ln most species the pileus is covered with a veil when young, the examination of which is indispensable for identification. lf only old fruiting bodies can be collected, on which no trace of the veil is recognizable, it is useless to try to identify them.

Many species produce only slender, delicate-capped, and very fugacious fruiting bodies. Therefore, they must always '15

be collected early in the morning, sspecially coprophilous species. They must be identifisd immediately or placed without delay in a preservative. Recipe Ior a fixative and preservative: 100 ml oJ a 35% solution of formaldehyde, 500 ml of a 96% solution oJ ethanol, 50 ml concentrated (glacial) acetic acid, 350 ml distilled water.

racters such as the width of the hyphae or hyphal ends and the kind of pigmentation, whether it is intracellular or encrusted, are important. The length of the cells of the hyphae in the pileal or lamellar trama also plays a role for some species. Some species with a +/- blue stipe and/or a blue pileus can fade to brown during development. Therefore, it is especially important always to collect young fruiting bodies.

The habiius o, the Jruiting body is also a characteristic feature, especially the shape of the pileus, whether it is conical, campanulate, hemispherical, convex, umbonate, umbilicate, indented, or has a papilla (see Volume 3, illustrations on p. Special literature: NOORDELOOS (1987, 1988, 1992).

under the microscope in KOH. However, this color is not important ,or identification. ln contrast, the shape of the spores is decisive.

Hypholoma Special litsrature: WATLING & GREGORY (1987).

Five main shapes are distinguished by NOORDELOOS (1988): (5) isodiametric, (4) heterodiametric, (3) nodose, (1) cubical, and (2) cruciform.

Lepiota s. l.

We did not present information on the volume (Vm) of the spores, because the calculation of volume is based on a rotational ellipse, which is not the shape of Entoloma spores.

Lepiota s. l. includes the genera Cysfo/epiota, Leucoagaricus, Leucocopinus, Lepiota s. slt., Macrolepiota, and Seiceomy' ces.

The structure of the pileipellis is also important lor identification to species. To observe the structure, one makes a radial section, preferably toward or in the center o, the pileus. Cha-

The metachromasia ofthe spores i. a. is important in separating

16

these genera. The method of determining this property is described in the chapter "Methods of study".

ln Macrolepiota the presence or absence of clamps can be important (especially in the "rachodes-venenata> complex). Needless to say, in the so-called "clampless" spscies it is sometimes possible to find occasional clamps after prolonged searching. We noted that during the vegetative period ot Leucocopinus ceprstipes many small white spheres were produced on the substrate, which disappearsd afler a few months. We interpreted these as sclerotia. We do not know whether they occur in other species ol Leucocoprinus also.

Pluteus The structure oJ the pileipellis is o, decisive significance for identifying the species; in addition, the presence or absence of clamps needs to be determined. Two main groups of species are distinguished on the basis of the structure of the pi-

leipellis: those species with a trichodermal pileipellis and those with a cellular to hymeniform pileipellis. The shape and structure of the lamellar cystidia are also decisive for identification. Special literature: VELLINGA (1990), ENDERLE 0986), OR-

Limacella Special literature: GMINDER (1994). Psathyrella Some species are rooiing or associated with buried wood. Panaeolus The spores of this genus do not fade in H.SO. and can be di-

stinguished microscopically from species ol Coprinus and Psathyrella in this way. ln addition, the spores have dilferent shapes in frontal and lateral views, as in Coprrnus. The dimensions oJ the spores are given in the same order as for Copinus, i- e. length x width ln lateral view x width in frontal view. Q-value without parentheses = lateral view, in parentheses = frontal view. Special literature: WATLING & cREGORY (1984.

Pholiota (Kuehneromyces) The taste of the flesh (mild or bitter) and the chrysocystidia (whether they are pressnt and where) play a role in identifying the species in this genus. We include both species of Kuehneromyces as a subgenus of

Pholiota (subgeneric name in parentheses). The most recent nomenclatorial status (WATLING & al. '1993): these authors elace Kuehneromyces as a subgenus ol Galeina.

Therefore, the fruiting bodies must be dug up carefully when collected. Many also have a universal veil, which often can be seen only in very young frbs. Thus very young frbs. need to be sampled also. Since practically all species are hygropha-

nous, specimens which still have

a water-soaked

pileus

(showing color changes) should always be selecied. Red-underlined lamellar edges are an important feature for identify-

ing some species. This character is a red line immediately below the generally white-floccose edge, which is visible only with a hand lens (see No. 330). ln all species the spores are +/- thick-walled. Since this property is not useful for separating the species, we have drawn the spores as single-walled for the sake of simplicity.

One property of psathyrellas is the nature of the cystidia on the lamellar edges. These consist of subglobose to pyriform and so-called pleurotoid cheilocystidia, which vary in abundance depending on the species. ln order to make an objective evaluation, one must make a long, narrow section along the free edge of the middle part of a lamella, showing only the cheilocystidia. Since the shape and size of the pleurocystidia and the pleurotoid cheilocystidia can vary considerably not only from one species to another, but sometimes even within the same Jrb., a number (10-20) of sections should always be selecled for observation. This is the only way to develop an image of the predominant shape. Three main shapes of pleu-

rocystidia are distinguished: lag€niform, utriform, and fusiform. 17

All species have a cellular pileipellis, but the structure can vary somewhat lrom species to species. However, thess difterences are oI little or no taxonomic value. Some species have a thin layer of hyphae above the pileipellis, which represents part of the universal veil and is found only in species with a well-developed veil.

How to use the keys

Only ths species included in this volume are included in the following keys. ln particular, the entirefamily Cortinariaceae is

omitted. This family contains those species with spores which are generally brown and have a verrucose to rough or tuberculate surface. This whole ramily will be treated in Volume 5. The tundamental character used for identifying any species is the color of thg spore dsposit on white paper (see Volume 3, pago 15).

Determining the color of a spore print is usually very subjective. Therefore, we have attempted to find the most objective and repeatable method. ln the lit., information on the color of the spore print (if presented at all) is often given by means of numbers, which refer to the color tables provided by various authors, e. g. MUNSELL (1988), KORNERUP & WANSCHER (1967), or KUPPERS (1981). Since lhis literature is not available io most ofthe users of our

books, we have prepared our own table. lt is bassd on the spore prints which we obtained ourselves. We read them into the computer with a color scanner and analysed them with

the color-processing program "Photoshop,, which determined the percentage of the color components in ths subtractive CMY color system. The data were finally coded according to the Euroskala-Norm and so could b€ used for color printing. More details about our procedure are in the chapter "Methods of Study,,, page 13. The color of the spore print is determined from dry deposits. ll necessary (f a spors print was not obtained) one can determine the color approximately from the color oI the lamgllae. However, only mature frbs. are suitable for this. This method is useful only under certain conditions, since color nuances cannot be judged. Furthsrmore, there are exceptions which can lead to the wrong keys (e. g- Melanophyllum haematospermum No. 258).

The keys begin with an entrance key which requires the choics of a spore color. The choice leads to one of three subsidiary keys. These in turn lead to group keys, which generally include a single genus or a group ol genera. A collection can be identified to species using these group keys. Except for the entrance key, the keys are dichotomous.

Entrance key 1

Remark6

This sp€cies could be conlused in nature with species ol Crepidotus, which also have oink-brown lamellae and occur on similar substratos. bul have subqlobose to elliptical, non-angular spores. Although thls collection would correspond better with Entoloma depluens (Batsch: Fr.) Hes. ln spore_size INOORDELOOS 1992: 8.5-11 x 7-7.5 um), we assigned it to E byssisedum, since we observed onlv l€rtile lamellar edoes without cheilocystdla. Anolher species which is similrr but smaller and ihite is E parasilrcurn (Ou6l.) KreisAl; il'occurs on old funoal fruiting bodies, especially ol Cantharellus and C6. tercllus. Entoloma unclatum (No.90)also can produce small. excenlrically sii' ped frbs., but it is daft gray-bown and usually has a central stipe,

Remarks The shape of the pileus is variable in our expedenco. Wo observed convex6onic, indented, and sllghtly umbilicate pilei within one week in the same locality. The species is characterized by the tomentose pileus, the dark blue pil€us and stipe, and the presence of clamps.

The variety described here differs from the type variety p marily by smaller spores. which on the average are not longer than '10 Um (type 9-13.5 x 6-9 um), and by somewhal smaller and diflerently shaped cherlocystidia. The cherbcystrdia of this collection conespond to the drawing in NOORDELOOS (1988), but not to those in NOOROELOOS (1987); later he showed the cysti dia for var. poliopus (NOORDELOOS '1992).

Thls very poisonous species was newly described by NOORDELOOS (1985) as Entoloma eulividum, because the names E s,nuatum and E. liwdum rcptesent two different species, and funhermore E /lvidrlm Bull. is unequivocally P/uteus cerv,hus. NOORDELOOS (1 992) no longer considers E sinuatulr, ss. Romagn., with white lamellae when young and a more gray-brown pilaus, as a distinct species, but merely as a rare form ol the species described here. We were able to find marginal cells in all our collections, which would indicateE rrosedarum Noordel. Howevet allparts ofthe latler speci€s are suppo-

sed to turn yellowish or reddish when rubbed, which did not occur in our collections. Collectors for the table should beware, since young frbs. can be confused with C/ifocybe nebula,s (Vol. 3, No. 170), which has white, slightly d€current lamellae ihroughout life, and does not smell or taste farinaceous.

Rhodocybe (Lasch: Fr.) Sing.

mundula

I A:

Usually gregarious, more rarely solitary in hardwood or coniferous for€sts, parks, on soil among grass or leaf or needle litter. Prelers chalky soils. Summer-fall. Rare. Distribution: E, A, As.

Macrogcopic teatures Pileus 25-50 (60) mm across, convex when young, later plane, usually with an obtuse umbo or somewhat indented, surface dry,

dull, smooth to pubescent-tomentose, also spotted or somewhat zoned, whitish when young, later remaining so or becoming graybrown with a lilac tint, margin incurved and inrolled for a long time, undulating in age. Flesh whitish, thin, reddening when cut and then tading, but also blackening, odor farinaceous-rancid, taste Iarinaceous, quickly bitter. Lamellae white when young, cream-colored to gray-ocherwith pink tones when old, broad, L = 3G45, I = 3-7, decurrent, strongly forked near the stipe, edges smooth, concolorous with the faces. Stipe 35-50 (60) x 5-12 mm, cylindrical, somewhat enlarged toward the base or also the apex, solid when young, hollow when old, rigid, elastic, stipe flesh not discoloiing when cut, surtace whitish-tomentose on a whitish to gray-brownish background, white-tomentose toward the base and base with white rhizoids. Surface of pileus and the lamellae spotting black when touched or rubbed. Swabbing any surface with KOH causes it to turn red-brown.

Whil€ A. fulva is commonly encountered here, A, crocea prefers warm regions and therefore is rare in our floristic area, The other species of vaqinate amanitas do not have orange-brown colors on the pileus.

This species can be eastly confused with Amanita vag,i?ata {No. 1 44), since it ditfels onlv sliqhlly macroscopicelly, e. g. by a non-umbonate pileus, sturdy stipe, and usuallyby veilremnanis on the pileus. The lwo species can beseparated with most certainty microscopically. ln contrast to A. vaglnate this species has broadly elliptical spores and more slender basidia. Although PI. l}us ha.lepensis was given as the associated lree in the original description (I\,IALENQON & BERTAULT 1970). the linds rn Europe mentioned in lhe lit. came mostly from hardwood forests.

Remarks The typacal form of Amanita vaginata has a gtay pileus without veil remnants on it. ll brown tones and/or veil remnants are present, the microscopic fea-

tures must be carefully examined, since such mushrooms may be another species, such as A. mairel (No. 141), A. battarae (No. 135), A. submembraracea (No. 143), etc. The microelements in the volva are an important diflerentiating leature.

This white amanita otten causes lile-threatening cases ol poisoning, not rarelyending in death, because it is confus€d with white, edible species ofAga,als, 6sp. wh€n young. While the lamellae of amanitas remain whit€, becoming at most off-white in age, those ofAgaflcus species soon turn pink, graypink, 10 purple-red or dark purple-brown because ot the dark spores. 11 is al-

so possible to confuse Amanite viosa w,lh Leucoagaicus ieucoth/tes (No, 240), also wh(e, which occurs primarily rn Oadens and meadows (not .n forests) and is edible. Another white species of bulbous, maaita which is de-

Remarka This species is charactedzed by the reddish-brown color of the pileus, the floccos€ annularzone, the white to cream-colored lamellae, and most impor tantly by the strongly amyloid, small (< 5 pm long) spores. The amyloid reaction is so strong that rt can be observed macroscoprcally. Srmilar species of Cystodema have eith& larger or inamyloid spores or a memblanous annulus. Cystodemla supe/bum (No. 207) has a conspicuously wine-r€d to purple-tinted pileus, bitter flesh, and inamyloid spores.

nemarks JAHN (1962) discussed the history of this species end gave a thorough description of it. He pointed out the peculiadty of th€ spores, which are not amyloid but hav6 an amyloid suprahilar spot. lt was difficult for us to repeat this observation, since we could not be sure that we were seeing truly amyloid hilar spots or were imagining the amyloid rcaction trom wishful thinking. KRIEGLSTEINER (personal commLrnication) has also had this difficulty. Furthemore, HUUSMAN'S (1958) comments also indicate this. This sp€cios is easily separated from the othe6 in the genus by the wine-reddish colorofthe frbs. Wine-reddish to lilac frbs. with white, free lamellaeshould be looked for in Limacella. Limacella vinosolubescons (No. 165) has wine-reddish frbs., but it is slimy and has a completely different pp without sphaerocysts,

Habitat Solitary to gregarious in dry lawns, pastures, among grasses, primarily at montaneto subalpine elevations. Summerjall. Rare. DE-

tribution: E.

Macroscopic features Pileus 20-30 (40) mm across, conical when young, later coniccampanulate to convex-plane, surface cream- to light ocher, dark ocher to red-brownish toward the centeG smooth, partly covered w,th distant, brownish, granular squamules, radially wrinkled and somewhat splitting when dry margin acute, tinely fringed, somewhat white-floccose when young. Fl€sh white, thin, odor raint and unpleasant to musty, taste mild, insipid, not distinctive. Lamellae whitish when young, light ocher when old, broad, L = 40-48, I = 1-3, ,ree, edges slightly floccose. Stipe 40-50 x 4-5 mm, cylindrical, hollow, tough, surface above the fibrillose annular zone white and slightly longitudinally fibrillose, surface below increasingly light ocher and longitudinally white-f ibrillose.

navicular, smooth, hyaline, dexvinoid, 10-16.2 x 4.5-6.2 um; Q: 1.7-3.0; Vm: 191; spp. cream-yellow. B: Basidia clavate, 25-35 x 9-12 Um, with 4 sterigmata and basal clamp. C: Cheilocystidia clavate, 1735 x 7-12 Um; pleurocystidia not seen. D: Pp compos€d of prostrate hyphae in part with erect ends 40-210 x 5-11 um, interspersed with clavate cells basally, all hyaline to with light brown pigmentation, septa with clamps. Remarks Thesynonyms listed above are considered to be separate species by certain aulhors, such as BON (1981) who gave i. a. different spore sizes ror them. The following spore siz€s are guen for L. oread,'formis: MOSER (1983) 1G-1a x 4.t-5.5 Um: CANDUSSO & LANZONI (1990) (l0) 11-14 (15.5) x 5-5.7 (6.2) Um; BON op. cit. ('10) 1'1-13 (15)x 5-6.5 pm. The spor€s in our collection were longer than these measurements and corresponded better to those ol L. /aevlrata Lge., which BON op, cit. gives as (12) 14-16 (19)x 4.5-6.5 pm. lt seems as if these species can hardly be separated on the basis of spore size and thal the species are probably conectly listed as synonyms. Lepiota a/ba (No. 213) is similar. bul lhe cente. of lhe pileus is not dislinclly darker in color,
