USTILAGO AFFINIS Ell. & Ev. — Ustilago affinis Ell. & 
Ev. Bull. Torr. Bot. Club, 201297. 1893. Ustilago hilariae Henn.,

1898. Ustilago americana Speg., Fung., Argent. Nov. Vel. Crit. 
no. 375. 1899. Ustilago stenotaphri Mass. Kew Bull. 153-4:184. 
1899. Ustilago henningsii Sacc. & Syd., Syll. Fung. 16:368. 
1902. 
Hosts: Hilaria cenchroides, Mex. (type U. hilariae Henn.) ; 
Stenotaphrum americanum, Bermuda, Jamaica (type). 
This fungus has been described a number of times during 
recent years by different botanists. The first named applied to 
it is apparently that used by Ellis and Everhart in 1893. Ustilago 
hilariae Henn. on Hilaria sp. does not seem distinct from the 
form on Stenotaphrum and so they have been placed together 
here. Ustilago stenotaphri of McAlpine is apparently a distinct 
species which was described in 1895. 
USTILAGO LORENTZIANA Thum.— Ustilago holwayi 
Diet., Bot. Gaz. 18:253. 1893. 
Hosts: Hordeum jubatum, Mont., N. Dak., S. Dak.; H. 
maritimum, Ida.; H. murinum, Calif.; H. pratense, Calif, (type 
U. holwayi), Utah; H. pusillum, Calif.; Hordeum sp., Calif., 
Wash. 
Dietel’s Ustilago holwayi does not seem to be specifically 
different from de Thumen’s species if one takes into considera¬ 
tion the variations that are met with in specimens from this 
country, some of which agree exactly with the South American 
type of the species. 
USTILAGO BROMIVORA (Tul.) Fisch. d. Waldh.— 
Cintractia patagonica Cke. & Mass., Grev. 18:34. 1889. 
Hosts : B'romus arvensis, Colo.; ? B. breviaristatus, Calif., 
Ia.; B. ciliatus, Colo.; B. hookerianus, Calif., Wash.; B. hor- 
deaceus var. glabrescens, Wash.; B. kalmii, Utah; B. margin- 
atus, Colo., Ore., Wy.; B. mollis, Wash.; B. racemosus, Wash.; 
B. secalinus, Calif., Ore.; B. vulgaris, Mont.; B. vulgaris var. 
eximius, Wash. 
An examination of the type of Cintractia patagonica shows 
it to be only an unusually vigorous form infecting the basal parts 
of the outer glumes as well as the inner parts. 
USTILAGO BROMIVORA var. MACROSPORA Farl.— 
Host: Bromus ciliatus, Colo (type), la.? 
This seems entitled only to varietal rank though the spores 
are much larger than those ordinarily possessed by the species. 
Specimens have been found on the same host that apparently 
belong to the species rather than this variety. 
USTILAGO CRAMERI Korn.—Host: Setaria italica, Ill., 
Ohio, N. Dak., S. Dak.
