 I. INTRODUCTORY STATEMENT 
 
 The study of the TJredinales of California began with the pioneer 
 work of Dr. H. W. Harkness and Justian P. Moore, who in 1880 
 published a Catalogue of Pacific Coast Fungi, which enumerates fifty- 
 five species belonging to this group. Unfortunately this list does not 
 give the specific names of a large number of the host plants referred 
 to and also the localities are often very indefinite, which makes it diffi- 
 cult to correlate this list with the work of subsequent collectors. Some- 
 what later Dr. Harkness, either in conjunction with M. C. Cooke and 
 J. B. Ellis, or independently, published in Grevillea and in the Bulle- 
 tin of the California Academy of Sciences a number of new species 
 including many Uredinales. The extensive collections of Pacific Coast 
 fungi which Dr. Harkness had presented to the California Academy 
 of Sciences before his death were destroyed in the great fire of 1906, 
 with the exception of the types of new species discovered by him, 
 which fortunately were preserved through the foresight of Miss Alice 
 Eastwood, the present Curator of the Herbarium.

 In 1882 Mr. E. W. D. Holway began work on the rust flora of 
 California by an extended exploration of King's River Canon and 
 vicinity, which brought to light a large number of species, some of 
 which were published as new by Dietel and Holway, especially in 
 Erythea and Hedivigia. With the aid of Mr. Holway this work was 
 continued by the writer, and collections were made in the region about 
 San Francisco Bay (1893 and later), Shasta and Siskyou counties 
 (1894), Tuolumne and Calaveras counties (1895), Lake Tahoe (1897), 
 and Mendocino and Humboldt counties (1896 and 1899). Contempo- 
 raneously and in the succeeding years a large number of collectors 
 did work in other regions. Of these especial mention should be made 
 of A. J. McClatchie (Pasadena), S. B. Parish (San Bernardino), 
 J. Burtt Davy (Berkeley), W. R. Dudley, and C. H. Thompson (Stan- 
 ford University). In more recent years extensive collections have 
 been made by Ellsworth Bethel, Carl T. Baker, David Griffiths, E. E. 
 Heller, Dr. Meinicke of the Federal Forest Service, and Professor 
 Home of the Agricultural Experiment Station of the University of 
 California. 
 
 II. THE NEED OF EXPERIMENTAL CULTURE WORK 
 
 Although much more extended collections and critical studies in 
 both field and laboratory must be made before our knowledge of the 
 California representatives of this group of fungi can be considered 
 either exact or complete, it is believed that an attempt to summarize 
 the information now available will be of assistance to those working 
 on the rust flora of the state and will give at least an approximate 
 idea of its extent and content. The need of systematic culture experi- 
 ments designed to establish with certainty the life histories of those 
 species which are known to be heteroecious is a pressing one. The 
 results obtained in other regions of the United States, especially 
 by Arthur and his collaborators at Purdue University, suggest 
 the species of host plants probably concerned in the life histories of 
 many of the Pacific Coast species; but the differences in the climatic 
 conditions of the two regions and of the species of host plants found 
 in them make it extremely desirable to confirm these suggestions by 
 actual experiments. It is to be regretted that owing largely to the 
 lack of such data it has been found necessary to include in the list 
 here presented a considerable number of form species, that is, aecial 
 and uredineal forms not definitely correlated with the mature forms
 
 Blasdale: Uredinales of California 103 
 
 necessary for their identification. Apparently an unusually large 
 number of Pacific Coast forms winter over, by means of uredineal 
 spores, and produce telia only occasionally and in very small amounts 
 or fail entirely to do so. 
 
 Culture experiments are also greatly needed for the purpose of 
 ascertaining the specific identity of many of those species which 
 develop on closely related host plants, such, for instance, as the forms 
 of Puccinia which are found on the different genera of the Onagraceae 
 and Compositae. Such experiments in other regions have shown great 
 variability as to the closeness of the adaptation between the rust 
 and its host. In some instances, as illustrated by the classical work 
 of Eriksson and Hennings with the grain rusts, this relation is an 
 extremely narrow one and it becomes clearly necessary to recognize 
 species or subspecies based upon purely physiological distinctions. 
 It has been shown by Bethel, on the other hand, that certain species, 
 such as Puccinia subnitens and P. stipae, produce their aecia on hosts 
 belonging to genera representing widely different natural families, 
 and it is not improbable that too much emphasis has been placed upon 
 the host plant as a criterion in ascertaining the specific limitations of 
 the rusts. 
 
 III. PLAN OF THE PRESENT PAPER 
 
 As one of the chief objects of the present publication is to assist 
 collectors in naming new collections and to tabulate all the known 
 forms and their accompanying host plants, the different genera, which 
 can usually be readily recognized if the mature form is at hand, have 
 been arranged alphabetically, and where a large number of species 
 are represented those species which occur on host plants belonging to 
 the same natural family have been grouped together and the groups 
 arranged according to the sequence of families found in Jepson's 
 Flora of Middle Western California. 
 
 The references cited are designed merely to identify with certainty 
 the form referred to and to indicate where a description of it can be 
 found. Only those synonyms have been given which are necessary to 
 show where certain species, whose validity is not accepted, belong in 
 the list. 
 
 The data represented by the list is based almost wholly upon speci- 
 mens in the herbarium of the writer, and the name of the collector 
 of each specimen cited is given in parenthesis except where the col- 
 lection is that of the writer, in which case it is omitted.

 IV. ACKNOWLEDGMENTS 
 
 The completeness of the survey of the rust flora of California here 
 presented is in a large measure due to the assistance of the collectors 
 whose names have been cited, who have furnished specimens or have 
 given additional data regarding them. Especial obligations are due 
 Mr. Ellsworth Bethel for a large amount of information regarding the 
 heteroecious species, and for extended collections of grass and sedge 
 inhabiting species from the southern part of the state both of which are 
 poorly represented in most of the collections which have been made 
 up to the present time. I desire also to express my thanks to Pro- 
 fessor J. C. Arthur, who read over the entire list of species here 
 presented and made many valuable suggestions. It will also be 
 obvious that much help has been derived from such portions of 
 Arthur's arrangement of the North American species of Uredinales 
 (North American Flora, vol. 7) as have been published, of the critical 
 work of Holway in that portion of his North- American Uredineae 
 which has been published, and Jackson's Uredinales of Oregon, pub- 
 lished in the Memoirs of the Brooklyn Botanic Garden. 
 
 V. GENERAL FEATURES OF THE UREDINALES 
 
 The Uredinales represent a group of fungi whose vegetative parts 
 consist of a much branched and septate mycelium, which develops in 
 the leaves, branches, and fruits of certain seed producing plants and 
 ferns and abstracts nourishment from the cells of the surrounding 
 tissues by means of haustoria. The reproductive parts are represented 
 by five different types of spores, one or more of which are frequently 
 lacking and which differ greatly as to form and size as well in the 
 mode of production and germination. The different spore forms are 
 the following: 
 
 Spermatia, designated by the symbol 0, are produced in sub- 
 globose or flask-shaped spermogonia and are minute hyaline bodies, 
 which can be made to germinate but do not appear to perform any 
 important function in the life history. They usually appear with 
 or slightly before the aecia. 
 
 Aeciospores, designated by the symbol I, are produced in cup- 
 shaped or cylindrical aecia, which have a more or less well developed 
 peridium, or in masses, frequently surrounded by paraphyses, in 
 which a peridium is lacking. They are always one-celled and are 
 formed by the successive abstriction of the ends of closely packed
 
 Blasdale: Uredinales of California 105 
 
 hyphae. They have a hyaline epispore and a number of germ pores 
 but rapidly lose their ability to germinate. 
 
 Urediniospores designated by the symbol II, are usually produced 
 in subepidermal sori and ultimately burst through the epidermis as 
 light brown or yellow pulverulent masses. They are produced singly 
 at the ends of hyphae, are always one-celled, either globose, elliptical 
 or pyriform, possess several germ pores and are either echinulate or 
 tuberculate. 
 
 Teliospores, designated by the symbol III, are formed like the 
 urediniospores, but sometimes appear singly, either in or on the tissues 
 of the host. They usually possess a definite pedicel and may be 
 fascicled or compacted into a crust or a cylindrical column. Each 
 spore may consist of a single cell or of as many as twenty cells; 
 each cell usually possesses a single germ pore. They possess a thick 
 epispore, which is dark brown or black in color. On germination 
 they produce a thick promycelial tube, which ultimately produces four 
 cells, each of which develops a single basidia and sporidium. "When 
 the sporidia germinate they produce short tubes which are able to 
 penetrate the tissues of the proper host plant. The formation of 
 basidia is one of the most distinguishing characteristics of the group. 
 
 Many species show well characterized alternation of generations 
 on host plants belonging to the same species (autoecious) or on host 
 plants belonging to different species (heteroecious).

 (Pursh.) Lindl., which he had infected with C. columnaris from Nova 
 Scotia, and Professor Frazier found aecia identical with those obtained 
 by Arthur on Abies balsamea at Picto, Nova Scotia. In California 
 Meinicke has collected similar aecia on Abies concolor Lindl. at Lake

 Aecia on Pinus ponderosa Dougl. (Peridermium pyriforme Peck) 
 Rocky Gulch, Siskiyou County (Meinicke). 
 
 Uredinia and telia on Comandra umbellata (L) Nutt. (Cronartium 
 Comandrae Peck), Shasta Springs. The genetic connection between 
 these forms was shown by Hedgcock and Long (Bull. 247, U. S. Dept. 
 Agr., 1914), also by Kirkwood (Phytopathology, vol. 5, p. 233, 1915). 
 
 15. Cronartium Quercus (Brond.) Schrot. 0, I, II, III 
 Sacc. Michelia, vol. 2, p. 308, 1881. 
 
 The aecial stage (Peridermium Harknessii Moore) produces 
 globose galls often of large size on branches of Pinus radiata Don, and 
 is sometimes very destructive. Also on P. attenuata Lemmon, P. muri- 
 cata Don and P. ponderosa Dougl. in the central Coast Ranges. 
 
 Uredinia and more rarely telia on Quercus agrifolia Nee., Q. Kel- 
 logii Newb. and Pasania densiflora Oerst., Gilroy, Mount Diablo, 
 Monterey (Meinicke), Mill Valley (Bethel), Santa Barbara (Bethel) ; 
 on Q. dumosa Nutt., Pasadena (McClatchie). 
 
 There seems to be no essential difference between the eastern and 
 western forms of this species, although culture experiments are needed 
 to prove this conclusively. Meinicke (Phytopathology, vol. 6, p. 225, 
 1916) has shown that aecial spores from Pinus radiata could be made 
 to reproduce aecia on the same host without an intervening stage; 
 also that the fungus winters over in the uredinial stage on the leaves 
 of Quercus agrifolia. 
 
 ERIOSPORANGIUM (BERTEBO) LEV. 
 Ann. Sci. Nat., ser. 3, vol. 5, p. 269, 1846.

 Vienne, p. 343, 1906. 
 
 The aecial stage is probably Coleosporium Baccharidis Cooke 
 (Grevillea, vol. 9, p. 7, 1880), which produces galls often of large size 
 on the branches of Bacchari-s consanguinea Greene and B. pilularis 
 DC, similar to those of the bark-inhabiting species of Peridermium.

 Uredinia and telia occur on the leaves of the same hosts, but as the 
 sori are small they are easily overlooked. The genetic connection 
 between the two forms has not been proven; but the frequency with 
 which they are associated makes it probable that they are so related. 
 It is common throughout the bay region and in southern California.

 brooms of some size, but the spore masses, which appear as brown 
 cushions on the smaller twigs and leaves, are not conspicuous.

 The genetic connection between the two stages was first established 
 by Arthur (Mycologia, vol. 1, p. 252, 1909, vol. 4, p. 57, 1912), who 
 succeeded in growing aecia on Crategus PringUi Sarg. from telia 
 obtained from Corvallis, Oregon. From the latter state it is reported 
 to be a rather serious pest by O'Gara (Science, vol. 39, p. 60, 1914), 
 and by Jackson (Phytopathology, vol. 4, pp. 41, 261), attacking 
 especially pears, quinces, and certain varieties of apples.

 Bot. Gaz., vol. 63, p. 504, 1917. 
 
 This genus is based upon the fact, first shown by Kunkel (Bull. 
 Torr. Bot. Club, vol. 40, p. 361, 1913, Am. Jour. Bot., vol. 1, p. 37, 
 1914), that the entire life cycle consists of a caeomoid stage associated 
 with pycnia, the spores of which germinate like teliospores. It is not 
 distinguishable morphologically from the aecial stage of the genus 
 Gymnoconia, but the aecial spores of the genus last named germinate 
 like true aecia spores, and there is an alternate stage not distinguish- 
 able from the telia of the genus Puccinia. 
 
 25. Kunkelia nitens (Schwein) Arthur. 0, I 
 Bot. Gaz., vol. 63, p. 504, 1917. 
 
 On Rubus vitifolius Cham, and Schl., Santa Rosa, on cultivated 
 blackberry, Orange, Berkeley, Chico (Copeland), Glendora (Baker), 
 Long Beach (Bethel). This is the widely distributed "orange rust" 
 of the blackberry formerly known as Caeoma nitens.

 On Rosa gymnocarpa Nutt., Amador County, type collection (Han- 
 sen), Plumas County (Meinicke), Paso Kobles and Yosemite Valley 
 (Bethel). Very little is known about the life history of this rust, but 
 its similarity to the preceding species makes it probable that it is also 
 a short-cycle form. It appears very early in the spring and produces 
 hypertrophy and ultimate death of the affected shoots.

 (Bethel) ; on 8. sp., Mill Valley and San Diego (Bethel) ; on Oryzopsis 
 hymenoides Eicker, Victorville (Bethel). 
 
 The connection between these forms has been established by Bethel 
 by repeated cultures with both telia and aecia, the first being made 
 in Colorado in 1912. His numerous collections of both aecia and telia 
 in 1916 and 1918 in southern California, not far from the type locality 
 of Roestelia interveniens establish the validity of the combination 
 given above. The aecia have very short peridia, split almost to the 
 base, as in the form genus Roestilia; the telia form sori from one to 
 three inches in length, especially on the sheaths, which are tardy in 
 rupturing.

 ADDENDA 
 
 The following represent important additions to the foregoing list 
 the data for which were received too late for inclusion in the proper 
 sequence. 
 
 231. Cronartium occidentale Hedgcock, Bethel, and Hunt. 0, I, 
 
 II, III 
 
 Jour. Agric. Kesearch, vol. 14, p. 411, 1918. 
 
 Aecial stage not as yet reported from California but found in 
 Colorado, Utah, New Mexico, and Arizona on species of Pinus belong- 
 ing to the piiion group. 
 
 Uredinia and telia on Ribes tenuiflorum Lindl., "abundant along 
 river wash near Monrovia" (Bethel). It was first reported from the 
 same locality by W. M. Phillipson. 
 
 This record is of especial interest on account of the similarity of 
 the uredinial and telial stages to those of the white pine blister rust, 
 the aecial stage of which is very destructive to pines of the five-leaved 
 group. 
 
 232. Gymnosporangium inconspicuum Kern. 0, I, III 
 
 BulL Torr. Club, voL 34, p. 461, 1907. 
 
 Aecia (Roestilia Harknessianoides Kern) on Amelauehier sp. 
 Telia on Juniperus occidentals Hook. Both forms collected by 
 Bethel in Bear River Valley, San Bernardino Mountains.

 On Pensteman spectabilis Thurber, Mount Lowe. 
 
 236. Puccinia yosemitana Blasdale, sp. nov. I, III 
 
 Aecia usually solitary and widely scattered, cylindrical, about 
 0.2 mm. wide and 2.0 mm. long, orange yellow ; pseudoperidia of thick- 
 walled cells with deeply-colored contents, finally dehiscing by disinte- 
 gration at apex. 
 
 Telia associated with aecia, amphigenous, scattered but occasionally 
 confluent, about 0.5 mm. long, elliptical, black, pulverulent, early 
 naked ; teliospores ellipsoid or oblong, rounded and but slightly thick- 
 ened at apex, barely constricted at septum, smooth, 32-38 by 20-22/A ; 
 pedicel thick, persistent, often 80/* long. 
 
 On Crilia pungens var. Hookeri Gray, found on trail from Yosemite 
 Valley to top of Yosemite Falls. 
 
 237. Pucciniastrum Galii Fischer 
 
 Ured. d. Sehweitz, p. 471, 1904. 
 
 Uredinia on Cralium triflorum Michx. Yosemite Valley. 
 3. Aecedium Trigochinis Diet, and Holway 
 
 It has been shown very recently by Bethel that this is one of the 
 many forms representing the aecial stage of Puccinia submitens. 
 
 67. Puccinia sejuncta Sydow. 
 
 It is now known that the form referred to under this number is 
 Aecidium Columbiense Ell. and Ev. (Erythea, vol. 1, p. 206, 1893).
