WILLIAM GILSON FARLOW
PREFACE THE primary object of this work is to indicate so far as recorded in the literature, for each host plant, all the fungi known to grow upon it and for each fungus all the hosts upon which it grows. In compiling such an index, most of the work is not botanical. One who knows the alphabet can sort the names and throw out duplicates. Some botanical experience, however, is needed to detect two or more names when they denote the same fungus, since synonyms are grouped in a brace. It is not the function of this work to solve botanical problems. Solutions may be included if available, but otherwise it must simply present problems to be solved by others. Some problems will be partially solved by studying the parasites on related hosts and some by studying those on unrelated hosts. They will suggest life histories to be traced in herbaria, cultures, and field work. Our geographical area includes the whole of North America and neighboring islands from Trinidad and Panama to the northern limits of plant life from Greenland to Alaska. From this area, we include all publications containing parasitic fungi which a diligent search of more than fifty years has brought to light. The early manuscripts by Doctor Farlow were incorporated in the edition of 1888-91, and the contents of that edition have been included in the present one. The effort has been continued along similar lines through 1923, and since that time only those were included that came to the compiler's notice up to July 1,1927. Beyond that date part 12 of Arthur's work on the Uredinales was included since it contained so many additions and corrections to the earlier parts. This index includes about 80,000 names of hosts and fungi as compared with 23,000 in the earlier work. The genera of host plants are arranged as nearly as may be in the sequence indicated by Engler & Prantl, Die natürlichen Pflanzenfamilien, the seed plants being interpreted by Dalla Torre & Harms, Genera Siphonogamarum. The arrangement of the algal hosts is contributed by N. L. Gardner. Species are alphabetically arranged in each genus. If several related hosts have the same parasites, the hosts are grouped together for convenience and the parasites are printed but once, e. g., Eriogonum, pp. 286, 287. Sometimes a host may be thrown slightly out of alphabetic order as in Berberis, p. 315. Insect groups are arranged systematically as far as families, and as far as subfamilies in the Coccidae. Insect genera and species are arranged alphabetically under the family or subfamily. In many cases a fungus has been men-

tioned as growing on a certain genus or larger subdivision without mention of the species, and hence in searching for fungi to be found on a given species one should examine the list of fungi placed at the end of the genus or other subdivision under the general heading "sp. indet." The naming of host plants is much more difficult than for the first edition. During the interval of forty years which has elapsed, usage has become very diverse, literature has multiplied and the geographic area has been extended to include regions whose floras are less familiar. Formerly names to be found in standard floristic works were preferred, while in the present index we have attempted to apply the International Rules of Nomenclature and to profit by special monographs in so far as limited time and library facilities permitted. The names selected are sometimes open to question. Also specific names current in 1891 often had a different significance from the same names at present, e. g., species of Acer, Rubus, Spartina, Myrica, and others. In choosing the correct host name, the value of the original statement is often impaired. On the other hand combinations for some species in genera recognized by Dalla Torre and Harms have apparently never been published, and to avoid any question of making them in this work, they have beeil treated as in the following example. In the sense of this index, Sericotheca franciscana, p. 359, belongs in Spiraea, but we have been unable to find that it has ever been formally designated as such. Therefore it is written: Spiraea (Sericotheca franciscana Rydb.) When the authority for a host name cannot be found, it is credited to the geographical division from which it came, e. g., "ex Kansas," or to the author who used it, e. g., "ex Duss." There has been great difficulty in finding authorities for host names; but this is not strange, for they are commonly written without authorities. The monograph of Quercus by Trelease arrived just in time to give needed help with the host species of that genus. Bailey's Manual of Cultivated Plants arrived also in the early stages of printing, and has served as a standard throughout. As a result, cultivated plants have been more carefully treated from a botanical standpoint than in 1891. In a few cases, as Brassica, Citrus, and Holcus, common names are given in addition to scientific names, especially for varieties. Where available books or skill in using them failed, the compiler has consulted specialists some of whom decline to be mentioned. Professor Oakes Ames has revised the orchid names, and assistance on special groups has been given by N. C. Fassett, the late J. N. Rose, P. A. Rydberg, and C. A. Weatherby.
PREFACE

Since it is not the province of the host index to designate a preferred name, each name has been written with authorities in full as if it were the accepted name. Each fungus name stands on its own merits and the compiler has not changed it by substituting or adding a name more correct or better understood. An exception is made to conserve space in the case of Agaricus. When an Agaricus name becomes a synonym of some other generic name, only the latter is given. The same name or a different name may designate the same fungus on a related host. By studying the names under different hosts, a considerable review of the synonymy may be gained, but each host has only the fungus names actually published for that host. The arrangement of synonyms is entirely different from that of the earlier work. In that the arrangement was chronological, giving the history of the name. To have continued such an arrangement, however, would have consumed an amount of time far beyond its additional value. The International Rules of Nomenclature adopted at Brussels have never before been carried into effect for fungi in general. They require, for example, that Fries should be written as authority for Polyporus cinnabarinus, but they give permission to those who wish to do so, to write Polyporus cinnabarinus (Jacq.) ex Fr. Some botanists have availed themselves of this permission, notably E. A. Burt in his work on Thelephoraceae. The compiler also has attempted to give these pre-Friesian authorities — consequently the authorities for names used by Fries and earlier authors were verified and their histories traced.1 For example, if the genus is not changed we should write Boletus cinnabarinus Jacq. ex Fr. If the genus has been changed by Fries, the name becomes Polyporus cinnabarinus (Jacq.) ex Fr. and by later change Trametes cinnabarina (Jacq.) ex Fr. When other authors change the genus, we have Polystictus cinnabarinus (Jacq. ex Fr.) Cke. and Pycnoporus cinnabarinus (Jacq. ex Fr.) Karst. Under Cenangium ferruginosum Fr., S. M. 2:187, the earlier name Peziza Abietis P. occurs as a synonym. This is a valid name because its identity is here recognized by Fries, and on this basis it is chosen by Rehm and should be written Cenangium Abietis (P. ex Fr.) Rehm. A few names as Rhizina inflata (Schaeff.) ex Quel, have been validated in this way by later authors. Certain early names have been in continuous use to the present time, but are not valid according to the rules, e. g., Hypoxylon coccineum Bull, and some of the Erysiphaceae as Erysiphe Cichoracearum DC. Such must be referred to the next congress and therefore have been marked with a dagger (f). 1 In this work, S. F. Gray's Natural Arrangement of British Plants, 1821, is considered to be later than Fries, Systema Mycologicum, also 1821. In practice Persoon's Mycologia Europaea 1822-1828 must be considered as the date of departure for some groups published in the later volumes of Fries, according to our interpretation of the rules.

PREFACE
Authorities for names originating since the established dates of departure are written as found, unless special reason for study appears. Since a name for a perfect form cannot be based on that of an imperfect form, the first use of such a name is treated as a new name and it can have only the author who used it. If it is then transferred to another genus, its parenthetical authority is the author who first used it for the perfect stage. The authority for Glomerella cingulata is not (Atk.) Spaulding & v. Schrenk because Atkinson described an imperfect stage. Stoneman first placed it as a perfect fungus, Gnomoniopsis cingulata, and the authority should be written (Stoneman) Spaulding & v. Schrenk. Aecidium Sarcobati Pk. is given as the aecidial form of Puccinia subnitens. When the specific name is used for the teleutosporic stage, the name becomes Dicaeoma Sarcobati Arth., not Dicaeoma Sarcobati (Pk.) Arth., and under Puccinia it is Puccinia Sarcobati (Arth.) Bethel, not (Pk.) Bethel. The compiler interprets the rule as above. Some, however, hold that while Sarcobati cannot displace subnitens for the name of the species, yet it may be written Puccinia Sarcobati (Pk.) Bethel. Under Thalictrum thyrsoideum, p. 315, is given / Dicaeoma Clematidis (Lagerh.) Arth. I. \ Puccinia montanensis I. Fung. Dak. 104. This is not Puccinia montanensis Ell. but was erroneously so indicated with reference to the aecidial stage only, therefore I. is placed before the authority. If this were the aecidial stage of P. montanensis Ell. the I. would be placed after the authority, and similar cases have had the same treatment. Under Anemone cylindrica, p. 308, are Puccinia missouriensis I. Arth, and Puccinia missouriensis III. Arth., each illustrating this same idea. There is no Puccinia missouriensis, but these two stages have been so referred. The plant called Puccinia consimilis in Barthol., N. Am. Uredinales 835 is not the true P. consimilis but it is P. monoica. Therefore it is entered as a synonym of P. monoica with N. Am. Uredinales 835 in place of the authority, for properly it has no other. When the usual authority is replaced by reference to page or number, the reference applies only to that particular place or possibly to two plants treated at that place, both different from the original to which the name belongs. For example Caeoma Roestelites Lk. is said to be G-ymnosporangium Sabinae and the original reference was not American. As used by Schweinitz the name is now known to represent two species both different from Link's. C. Roestelites S. Am. Bor. 2900 p.p. 1 is Gymnosporangium Juniperi-virginianae, p. 366; C. Roestelites S. Am. Bor. 2900 p.p. 2 is G. globosum, p. 363. On p. 627 it is necessary to divide a parenthetical authority in like manner. See Pseudotthia in two braces. Aecidium Compositarum, var. Eupatorii (S.)
PREFACE

Β., p. 641, is not a variety of A. Compositarum Mart, and there is no authority for A. Compositarum as thus modified. The entire name must be regarded as an entity with the authority (S.) B. whose real identity is expressed by the name Puccinia Eleocharidis Arth. I. When two or more authors have used identical names they are marked by dates of publication, e. g., Dicaeoma Grossulariae and Aecidium Grossulariae, p. 351. Forms entered in the previous edition as species of Erineum are omitted in this, but an occasional name may have been overlooked. At least one named Erineum is a true fungus, Cercospora fuscovirens Sacc., p. 518. Fungi parasitic on insects are omitted from the secondary host; but fungi parasitic on fungi are given with both primary and secondary host, e. g., Darluca Filum on Puccinia Asparagi on Asparagus officinalis. The position of a brace of synonyms is determined by the name thought to be most important. If the name expresses only an imperfect stage, that is dominant, e. g., Dicaeoma poculiforme I. is placed as Aecidium, Cronartium Comandrae I. is Peridermium, Gymnosporangium globosum I. is Roestelia. Under Viola papilionacea, p. 516, the alphabet is to be interpreted as Aecidium, Cercospora, Puccinia. When the number of parasites on a single host is large, the names are arranged under the proper orders and where there are many species of some orders and few of others, the latter are placed under the general heading Miscellanea. Close adherence to a system of classification results in too many short lists in groups having comparatively few parasitic species. No botanical question is involved since the function of the host index is not to classify but to arrange for convenience in finding. Under Quercus coccinea, p. 249, and elsewhere, the Erysiphaceae require a separate grouping and are removed from the Pyrenomycetineae where they belong and for convenience placed before that group as if coordinate. Under Sambucus canadensis, p. 623, Uredinales and Basidiomycetes are used as if coordinate. A fungus whose perfect stage is known is often placed with synonyms under the imperfect stage if the latter is more evident, more abundant, or more destructive. Variant spellings are not rare. Host names are spelled as indicated by the best authorities. Fungus names are spelled as originally indicated by their authors. Many discrepancies result. On Allionia is Albugo platensis and elsewhere is the host name Chrysothamnus plattensis. On Rynchospora cyperoides are Guignardia Rhynchosporae and Uromyces Rhyncosporae. On Plumiera is Coleosporium Plumierae and Septoria Plumeriae. On Wisteria we find Septoria Wistariae and Botryosphaeria Wisteriae. Under Gleditsia are specific names of fungi Gleditschiae, gleditsiicola and gleditschiicola. DeToni names Aecidium Kellermannii on Baptisia while elsewhere the spelling is Kellermani (from W. A. Kellerman). The earliest form for Marssonia
xii
PREFACE
has "ss" from Marsson (see Fung. Eur. 1857). Nummularia is correctly copied and so is Numulariola. The adjective hainensis is correct for one species and hainaensis is correct for another, pp. 418, 440. As the earliest form Fries wrote Polyporus pargamenus, much later he wrote P. pergamenus. Gray's Manual, 7 ed., gives Osmorhiza; species of fungi growing on it are Osmorrhizae. Yuccogena is preferred and allowed since Yucca is not a classical word. Genipa is correct but the parasite is Phyllachora Gnipae. On Ludvigia are fungi whose specific names are Ludwigiae. Septoria Lobeliae-syphiliticae grows on Lobelia siphilitica. Cercospora Asclepiadorae grows on Asclepiodora. An interesting variety of spellings will be found under Aplopappus venetus, p. 651. The genus Sabatia is host to species named Sabbatiae. On Kalmia, Sphaeria atriella is Zignoella atrella. Patellaria agyrioides is made a synonym of Lecanidion argyroides, p. 78. Valsa nigrofacta becomes Valsaria nigrificata. Helianthus tracheliifolius is host to Aecidium trachelifoliatum. Uredo Kyllingiae grows on Kyllinga. Ipomoea pandurata is host to Cystopus Ipomoeae-panduranae. Vernonia missurica is a host name, p. 638, Puccinia missouriensis is a fungus, p. 308. At the time of going to press, a paper on Pestalotia by E. F. Guba is received in which the treatment of the species and hosts is greatly improved. Persons having occasion to look up any species of Pestalozzia in this host index should consult this paper (see Phytopath. 19:191. 1 April 1929). Species names are decapitalized whenever possible, but the capital is retained for specific names which at some time have been generic names and for genitives of generic names and personal names. In case of insects, however, only those retain the capital which are genitives of personal names. Where possible ae becomes i in compound specific names, e. g., striiformis; -cola should never be written -colus or -colum, e. g., acicola; caerulea, Latin, should not be written coerulea, which implies Greek origin and a different meaning. To express doubt, the question mark is used. Following a fungus name it questions the accuracy of the determination and placed before a name or brace it expresses doubt regarding the host plant. Before a name in a brace it questions whether the name is truly a synonym of the others in the brace. The hyphen is used in specific names which consist of two distinct words, as Juniperi-virginianae but otherwise only when necessary to separate vowels as in albo-atrum. The asterisk (*) marks items not American introduced by way of explanation. The dagger (f) marks names which are not valid according to the International Rules and should be considered by the next congress. Numbers which refer to specimens are in italics as Puccinia monoica N. Am. Uredinales 835.

The following fungi are noted as needing to be properly described, renamed or the combinations formally made: Puccinia graminis P., var. Tritici-tertii, p. 129. Eutypella spinosa (P. ex Fr.) Coons, p. 257. Glenospora ramosa (S.), p. 272. Uncinula Petersii, p. 278. Endothia Ravenelii, p. 354. Marasmius musicola McDougall 1925, pp. 212, 217, presumably not Murrill 1915, p. 183. No pains have been spared to make the index as complete and accurate as possible. It is not to be expected, however, that it will prove to be free from errors and omissions. The following have generously contributed their services in reading proofs and in many other ways: J. F. Brenckle, Edith K. Cash, Margaret B. Church, G. P. Clinton, J. J. Davis, J. Dearness, C. W. Dodge, Η. M. Fitzpatrick, C. H. Kauffman, C. L. Shear, P. Spaulding, F. L. Stevens, R. Thaxter, and C. Thom. The Peridermia of Abies have been revised by J. H. Faull, fungi on Citrus by H. S. Fawcett and Anna E. Jenkins. The entomogenous fungi have been revised by R. Thaxter. Nathan Banks, Curator of Insects in the Museum of Comparative Zoology, has generously given expert information regarding insect hosts. Miss Eleanor H. Nickerson has helped with acute discernment and untiring industry, and A. P. D. Piquet has helped with the preparation of manuscript and correction of the proof of this as well as for the first edition. Dr. Susan P. Seymour has given valuable help in preparing the manuscript; Mrs. Anna C. Seymour has read proof for nearly all of this, as also for the first edition; Miss Mary E. Seymour has supervised part of the preparation and given other constructive assistance. In conclusion it should be mentioned that the publication of this index has been made possible only through the constant interest and material assistance of the late Mrs. Farlow. The compiler is grateful to all who have helped to make the book more accurate and more useful. FARLOW H E R B A R I U M OF CRYPTOGAMIC B O T A N Y
