At the time of his death (13 August 1937), Dr. Clinton had accu- mulated many additions and corrections, and these have been utilized in the preparation of the following pages; but they were not in shape for publication, and this text has been pre- pared by the fellow-worker who was associated with him for many years in the study of this group of plants. Financial aid was given to this work by the Connecticut Agricultural Experi- ment Station. Self-evident errors, and such as may readily be detected by reference to the bibliography or index, are not listed here. The names of newly listed hosts are preceded by an asterisk (‘‘*’’). For convenience of reference the keys to the species of the larger genera have been corrected and revised, and are here reprinted in full. USTILAGINACEAE 1, USTILAGO A.

Part 14, 1939] ADDITIONS AND CORRECTIONS 979 Add the note: In western specimens on certain hosts, as Puccinellia and Sitanion, the sori often occur in the inflorescence and leaves as linear striae, and on other hosts only in the leaves. In the east, on Panicum virgatum, from Staten Island, the striae also break out on the leaves. These unusual forms are difficult to distinguish by their spores alone from either Ustilago hypodytes or U. longissima (normally on the leaves), but are placed here under the former chiefly because of its great variety of hosts, in some of which the outbreaks occur on tissues other than the culms. 6.

DISTRIBUTION: Europe, Africa, Asia, southern United States. ILLUSTRATION: Beitr. Krypt. Schweiz 3*: f. 6. Exsiccati: Barth. Fungi Columb. 4998. Nore: This species seems to be quite near Ustilago affinis. U. Dregeana, as originally described by Tulasne on an undetermined grass from Cape of Good Hope, has echinulate spores, but otherwise seems to agree; this species was later reported on Cynodon Dactylon from Africa, by Kalchbrenner, but with much larger spore-measurements, 12-15. Ustilago paraguariensis Speg. also on this host, has larger spores as shown by the specimens from South Africa in Vesterg. Micr. Rar. Sel. 1322. It is quite possible that the Kalchbrenner specimen is the same as this last, as the specimens are somewhat similar. The original specimens need to be examined to determine the questions involved. 13b. Ustilago Jacksonii Zundel & Dunlap, sp. nov. Sori on upper parts of culms, running into and aborting the inflorescence by involving the pedicels, often containing empty spore-like cells the nature of which has not been determined; spores dark-reddish-brown, ovoid to subspheric, granular-verruculose, chiefly 9-12 in length.

On POACEAE: Microchloa indica (M. setacea), Aguas Calientes, Distrito Federal, San Luis Potosf. ‘TYPE LocaLity: San Luis Potosi, on Microchloa indica. DISTRIBUTION: Central Mexico. Norte: This comes nearest, perhaps, to Ustilago Mulfordiana, but differs distinctly from that species in the somewhat larger smooth spores. In color and brittleness of cell-wall the spores resemble certain species of Cintractia on the sedges. Looking at the spores as ordinarily seen in the circular outline, the wall over the center appears much thinner and so less opaque than the thick equatorial wall and often has a small ruptured area in the center. Whether this rupture is due to the fragile nature of the wall, or has to do with germination, we do not know; it suggests Cladochytrium or similar genera. The toothed character of the columella or rachis is due to the remains of the spikelets, which are borne in a one-sided simple spike. 50b. Ustilago sphaerocarpa Sydow, Ann. Myc. 15: 145. 1917. Sori in the ovaries, evident as oblong bodies between the glumes of one or more spikelets, 3-5 mm. in length; spores rather regularly subspheric or spheric, dark-reddish-brown, opaque, apparently smooth but obscurely verruculate under an oil-immersion lens, 15-18 p, rarely 20 yu, in diameter. On POACEAE: Festuca amplissima, Distrito Federal. ‘TYPE LOCALITY: Popocatepetl, on Festuca amplissima. DISTRIBUTION: Mexico. Nore: This species comes very close to U.

ILLUSTRATION: Ann. Acad. Sci. Fenn. A. 17: 519, f. 9. Nore: This smut agrees with the specimen originally described from Holland on Luzula campestris and since reported from several European countries on this host and other species of Luzula. Usually mixed with and adhering to the spores or in masses, one finds numerous minute sporidium-like hyaline bodies probably budding yeast-fashion; whether these are con- nected with the spores in any way I do not know. ‘They sometimes appear to be broken off tubercle-like projections, but are not. Not reported before from America. If the germination had not been given in the original description as producing lateral as well as terminal sporidia, I should say from appearances that this was a Tilletia instead of a Ustilago. The specific name is variously spelled by different authors. Sydow (Bot. Jahresb. 22: 84. 1894) says it was described as occurring in anthers and ovaries; he also says it is distinct from Ustilago capensis Reess, which seems to be the only species with which it might be confused. 20.

Alsine praecox, Idaho. * ape collected at Falk’s Store, Idaho, April 22, 1911, on Alsine praecox (Stellaria praecox) . Nelson. DistrrBuTion: Idaho and Washington. Nore: If Ustilago Duriaeana Tul. on Cerastium and Arenaria, and Ustilago Holostei DeBary on Holosteum are distinct species, then the above is also distinct, as it differs from either of them more than they do from each other. Yet these three seed-inhabiting species are certainly very closely related, and the slight differences may even be due to the hosts. Our species differs decidedly from U. Duriaeana, but perhaps less decidedly from U. Holostei, in its dark or black-purple spores, while these other species in all of the specimens examined have lighter reddish-purple spores. Its spores also, on the whole, are smaller, more regular, and with more minute reticulations that extend out at the margins as inconspicuous papillae rather than as wings, especially as compared with U. Holostei. It is entirely distinct from Ustilago violacea and its related forms that occur in the anthers of similar hosts. Nelson writes: “I find that we have abandoned S. praecox as a species, reaching the conclusion that its peculiarities repre- sented abnormalities due to seed-infection.” 62c. Ustilago Duriaeana Tul. Ann. Sci. Nat. III. 7: 105. 1847.

ON POACEAE: Pennisetum alopecuroides (P. japonicum), Virginia. Type Locauity: Tokyo, Japan, on Pennisetum japonicum. DISTRIBUTION: Virginia; also in Asia. Nore: Reported from this country only from Arlington Farm of the United States Depart- ment of Agriculture on a collection made by C. V. Piper, October 11, 1915. Although closely related to Ustilago Penniseti Rab., it differs in the slightly larger spores which are distinctly granular-verruculose. It is even more closely related to, if not identical with, Ustilago Pappiana Bacc., which despite the original description has spores granular-verruculose under an immer- sion-lens though the sorus seems to be shorter and more globose. Ustilago Schefferi Sydow is also closely related but infects the entire inflorescence. All four smuts have Pennisetum species for their hosts and at least U. Pappiana and U. Penniseti seem to be species of Sphacelotheca. We have not seen Ustilago kamerunensis Sydow also on Pennisetum, but the spores are described as considerably smaller, 6-84. Tolyposporium Pennicillariae Bref. on Pennisetum (Penni- cillaria) is quite distinct. Sphacelotheca occidentalis.

(See page 1029.) ON POACEAE: Cymbopogon sp., Panama. Type collected near El Bogrete, Prov. Cherique, Panama, September—October 1911, by A.S. Hitchcock. Note: The meager type specimen was labeled “‘Ustilago spermoidea Berk. & Br. ?” by Diehl, but it does not agree with that species, which is also a Sphacelotheca, or with any of the smuts we have seen so far on either Cymbopogon or Andropogon. Both the large regular spores and the sori combined with the ovaries distinguish it from these species. (U.S. Nat. Herb. 925602.) ‘The description was written by Dr. Clinton, without a specific name.

Add the illustration: Beitr. Krypt. Schweiz 3?: f. 33. Add the note: Part of the specimens on Andropogon barbinodis involve the entire inflorescence, forming the normal linear sori, and others only partially destroy it, some- times being confined to the individual spikelets and forming more irregular or shorter and broader sori. The collection from Aguas Calientes was unusual in that the packet contained not only this species but also Sphacelotheca Andropogonis-hirtifolii (P. Henn.) Clinton, distinguishable by the larger spores with more evident verruculations under an immersion-lens. That the two species are closely related and difficult to distinguish (and yet they seem quite distinct when the spores are mixed together on a slide under the microscope) is shown by both species having not only this host but also Andropogon saccharoides, if these hosts have been correctly determined. ‘The specimen on the latter host listed from Arizona in our monograph of Ustilaginales, under S. Andropogonis- hirtifolit, we have now decided belongs here, though the two specimens from Mexico on the same host do not. Insert: ’ 9a. Sphacelotheca erythraeensis (Sydow) Clinton. Ustilago erythraeensis Sydow, Ann. Myc. 9: 144. 1911. Sori in the inflorescence, not wholly hidden by the enveloping leaf-sheaths, oblong- linear, about 1 cm. in length, protected by a definite false membrane which breaks away from the top disclosing the brown-black semi-agglutinated or dusty spore-mass and finally the distinct columella of plant-tissue; sterile cells scattered somewhat in subspheric groups within the spore-mass, those of the false membrane cohering rather permanently or separating somewhat upon pressure into threads of two to several cells in a row, hyaline, subspheric, about the size of the spores; spores chiefly subspheric or spheric, light-reddish- brown, when young apparently smooth but with age distinctly minutely-verruculose, 10-12 » in diameter. ON POACEAE: Hackelochloa granularis (Manisuris granularis), Arizona; Guerrero. TYPE LOCALITY: Eritrea, northern Africa. Distripution: Arizona; Guerrero; also northern Africa. Nore: This species, collected first by Griffith & Thornber in Arizona, and later by Hitch- cock in Balsas, Guerrero, Mexico, agrees with specimens of Sydow’ s Ustilago erythraeensis as issued in his Ustilagineen (451), though the spore-measurements given in his description are slightly smaller than we make them from his own specimen. ‘The American specimens are younger and the spores are therefore apparently smooth though the verruculations can be seen indistinctly with an immersion-lens. Hitchcock in his Mexican grasses places this host under the genus Rytilix. The evident false-membrane, with the distinct sterile cells within the spore- mass, pieces the fungus, under our system, in the genus Sphacelotheca, to which we have trans- erred it here.

Sori in the inflorescence, entirely aborting it and so appearing as if on the stem, at first enclosed in the leaf-sheaths but finally more or less exposed, showing as linear bodies 2-5 em. in length, protected by a prominent light-colored false-membrane which gradually wears away revealing a black dusty spore-mass that becomes dissipated and leaves behind only a prominent columella of plant-tissues; sterile cells of membrane cohering rather permanently but upon pressure separating somewhat into threads, cubic to more elongate and often somewhat rounded at the ends, eventually semigelatinized, smaller than the spores; spores dark-reddish-brown, subopaque, chiefly subspheric to spheric, regular though often cupped on one side, and so somewhat flattened-elliptic in side view, with apparently smooth wall (about | » thick) but under an immersion-lens minutely granular- verruculate, chiefly 15-18 » or rarely 14-21 » in diameter. ON POACEAE: Andropogon bicornis, Vera Cruz. TYPE LOCALITY: Joinville, Santa Catharina, Brazil. DISTRIBUTION: Vera Cruz; also in Brazil. Norte: The specimen from Mexico is entirely distinct from Ustilago bicornis P. Henn. on the same host from Brazil. It does agree, however, with Ustilago culmiperda Schroet. as de- scribed by Hennings, which was also on this host from Brazil, and with the co-type specimen collected by Ule. We could find no evidence in either of these mature specimens that the spores are formed in balls, as in Sorosporium, and we have no hesitation in placing it in the genus Sphacelotheca because of the prominent false membrane. It has the largest spores of any of our species, so far placed under this genus. It is very close to if not identical with Sphacelotheca (Ustilago) leucostachys P. Henn. on A. leucostachys, but differs in being granular- verruculate instead of apparently smooth under an immersion-lens. 9c. Sphacelotheca Kellermanii Clinton & Zundel; Zundel, Mycologia 22: 142. 1930. Sori in the inflorescence, bunched and forming witches-broom effect, but individual sori linear elongate, usually 2-4 cm. in length; sterile membrane conspicuous, breaking irregularly into elongate strips (disclosing dusty spore-mass and eventually the elongate recurved columella of plant-tissues) but not separating easily into the individual cells (hyaline to reddish-brown tinted), these chiefly oblong to cubic and smaller than the spores; spores dark-reddish-brown, subopaque, angular, irregularly oblong to subspheric, distinctly granular-verruculate under an immersion-lens, 10-16 yu, rarely 18-20 yu in length. On POACEAE: Andropogon leucostachys, Guatemala. Type Locatity: Los Amates, Guatemala, on Andropogon leucostachys. DISTRIBUTION: Guatemala. Norte: This species is closely related to Sphacelotheca Holwayi Clinton & Zundel (Bolivia) on Andropogon bicornis, but differs in the occasionally more elongate spores and in the more evident granular-verruculations. It is even more distinct from Sphacelotheca (Ustilago) leucostachys on the same host since the latter has quite regular, subspheric, larger spores and a simple sorus. This description is based on three collections made by W. A. Kellerman in Los Amates, Guate- mala, March 15, 1905, and January 15 and February 15, 1908. The host was determined by Agnes Chase.

Nore: We find some variations in the size and markings of certain specimens on this host from America; at first this led us to place some of them under Sorosporium Syntherismae, which it very closely resembles. But upon further examination we found it difficult to draw the deciding line, and in the end we placed them all together here. The abnormal specimens usually have larger more irregular spores and under an immersion-lens often show more or less evident indications of verruculations in their walls. 10b.

Note 2: Kérnicke speaks of the panicles as sometimes being only partially destroyed and bearing spikelets but in none of the specimens seen by us was this the case. This fungus differs distinctly from Ustilago Rabenhorstiana on the same hosts, in the smaller smooth spores and the presence of the false membrane, which, in our treatment of the smuts, places it in the genus Sphacelotheca. It is very closely related, however, to Sphacelotheca (Ustilago) Panici-miliacei and S. Panici-leucophaei, being perhaps intermediate and hardly to be told from them by the spore-characters.

DISTRIBUTION: Massachusetts to Florida. Nore: This species was first collected September 27, 1911. Farlow, in sending the speci- men to the writer in October, wrote: ‘‘I supposed it was the usual Cintractia on Rynchospora of which I found a solitary specimen at Chocoura this summer on R. alba, but the Magnolia specimen has different spores which do not seem to be arranged like those of Cintractia. They seemed at first to be arranged in twos but on further examination they seem rather to be lunate or crescentic spores which in drying have the ends rolled in so they meet and when seen in front view look like two spores adhering together.’’ The spores give the impression of being those of a Schizonella, but a careful examination of the earliest stages shows that they have this cupped shape when still quite young, and there is no indication that two spores were originally found together and have fallen apart, as the cupped character might indicate. Furthermore, the young spores show the centripetal development of Cintractia. C. Taubertiana has spores about this size but more angular and without the peculiar cupping. C. Leveilleana R.

Nore 2: This species possesses the characteristic false membrane of Sphacelotheca and according to McAlpine the spore-balls of Sorosporium. Potter (Jour. Agr. Res. 2: 340. 1914) follows McAlpine in this classification. After a careful examination of the descriptions and illustrations of both these authors, and a slide sent by the former, we are still somewhat in doubt about the matter. Examination of mature spore-bearing material rarely shows any very characteristic spore-balls, although there is often an association of spores in irregular groups likely to be found with various smuts. Since, however, we have not had a chance to examine the fungus thoroughly in its various immature stages, we accept McAlpine’s classification with these expressed doubts—to be removed or confirmed by further study if opportunity permits. 38.

Bain, October 10, 1892, at Jackson, Tennessee, and was sent to us by Professor Hesler. It is on a new host and does not agree exactly with the European specimens, but this may be due to immaturity. The spores often appear coarsely spiny or tuberculate, rather than reticulate, but the wings can usually be seen at the circumference. The type on Agrostis vulgaris causes a stunting of the plants, which are then sometimes known as A. pumila; also found on A. stolonifera. Tilletia Earlei.

Palmer (453) at Beaver City, Utah, in 1877, and sent to us by J. C. Arthur. It seems to agree much more nearly with U. magica than it does with U. Cepulae. The spore-balls are chiefly 19-35 » in length, and rather closely covered with reddish-brown, rather thick-walled sterile cells, 5.5-9.5 » in length, with generally one, rarely two fertile cells (reddish-brown), these chiefly subspheric to oval but often somewhat irregular and 15-19 win length.

Clinton, at Centerville, Connecticut, April-May, 1908. DISTRIBUTION: Connecticut and New York. Norte: This species is quite distinct from Uvocystis Colchici on Colchicum and even from the darker-spored form on Muscari and Camassia by the very dark spore-balls with the in- definite collapsed sterile cells completely and permanently covering the spores. It is almost impossible to measure the spores on this account and the real nature of the sterile cells is only surely made out by boiling the infected tissue in a weak solution of caustic soda. We know of no other species of Urocystis with such permanent spore-balls and with so completely col- lapsed and tightly adhering cortex that resembles more an outer ridged coat than distinct cells. To a certain extent the species approaches the genus Tuburcinia. ‘The type was associated with Ustilago Heufleri. Urocystis Colchici. Add the synonym: Tuburcinia Colchict Liro, Ann. Univ. Fenn.

It differs from Urocystis coralloides Rostrup, the only other Urocystis on roots reported in America, by having darker- colored sterile cells and a quite different host. 13b. Urocystis coralloides Rostr. Bot. Centr. 5: 126. 1881. Urocystis Sophiae D. Griff. Bull. Torrey Club 34: 209. 1907. Sori occurring chiefly as wart-like tubercles on the upper portion of the roots, usually about 2 cm. below the surface of the ground, irregular, consisting of spore-balls finely packed together, 1 mm. to 1 cm. or sometimes larger; spore-balls subspheric, somewhat irregular, chiefly with 1-3 or sometimes 4 spores completely surrounded by yellowish- tinted sterile cells, chiefly 30-40 u in diameter; spores spheric to subspheric, often flattened due to compression, dark-reddish-brown, smooth, 15-17 u in diameter.

Myc. 26: 20. 1928) gives Entyloma Brefeldii with Enty- loma crastophilum on Holcus lanatus as a synonym of a new species which he calls Entyloma Sydowianum Cif. Entyloma Brefeldii was described by Krieger (Hedwigia 35: (145) 1896) on Phalaris arundinacea. Sydow issued several specimens in his exsiccati under this name, but on Holcus lanatus, one of which (Rab. Fungi Eur. 4202) was sent to him by Krieger. This fungus makes no spots that can be seen in the old dried leaves, and the spores are chiefly spheric and hyaline to light-yellow, so that to us it seems to be quite different from the species with darker-colored and often angular spores that makes dis- tinct black spots on the leaves produced by Entyloma crastophilum. 60.

We have not seen this species, but it differs apparently in the smaller spores and larger cortical cells, and according to Ciferri might be considered by some as a variety of D.

We have seen no specimen of this Doassansia which is the only smut reported on this host-genus or its family. Ciferri gives the spore-balls as 180-200 » and the spores as 12.5-18 yw in diameter. Doassansia Limnocharidis Ciferri, Ark. Bot. 23A™: 23. 1931. Sori on leaves, causing more or less round, brown, confluent spots (dirty-white in center and here slightly inflated), with a tendency to form multiple rows parallel to the midrib, rarely toward the margin, 2-3 mm. in diameter; spore-balls in the spongy parenchyma, irregularly spheric to elliptic, with fertile cells generally in a single ring surrounding a parenchymatous center, 100-160 yu in length; cortical cells elongate, subhyaline, with rather thick walls (2—2.5 w), 10-14 X 3-8 yw; paren- chymatous cells irregularly |polyhedric, subhyaline, 6-10 uy X 3-5‘; spores firmly adherent elliptic to subelongate, yellowish-brown, with smooth thin epispore, normally 9-13 yp X 4-6 un. On ALISMACEAE: Limnocharts flava, Santo Domingo. ILLusTRATIONS: Ark. Bot. 23A™: pl. 3, f. 10. We have seen no specimen of this smut, but from Ciferri’s description it differs from Doassansia Alismatis on the same host-family by being a Doassansiopsis instead of a Eudo- assansia, and apparently has smaller cortical cells and spores.
