Host: Triodia cuprea (Tricuspis seslerioides), Mo. (type)* 
This species bears the above name in the U. S. Dept. Agr. 
Herbarium and is evidently new. The writer is indebted to Mrs. 
Flora W. Patterson for the privilege of examining specimens. 
The fungus was collected by M. B. Waite at Charleston, Mo., 
in the fall of 1889. It is related to Ustilago spermophora but 
has spores that are more regular, more prominently verruculo- 
echinulate and darker colored. 
USTILAGO MINOR Nort.—Host: Bouteloua hirsuta, 
Kans. (type). 
Griffiths has listed a number of additional hosts for this 
species but they seem to the writer, who has examined the type 
of the species, to come more properly under Ustilago hieronymi. 
The specimens assigned to these two species show such variation 
that it is difficult to determine where the specific lines should 
be drawn. 
USTILAGO HIERONYMI Schrot.—Ustilago filifera Nort.,. 
Trans. Acad. Sci. St. Louis 7:237. 1896. 
Hosts: Bouteloua aristidoides Ariz., Mex.; B. bromoides, 
Ariz.; B. eriopoda, Ariz.; B. oligostachya, Ariz., Kans.’ (type 
U. filifera), Mont.; B. polystachya, Ariz.; B. racemosa, Kans. 
(type U. filifera), Tex.; Pappophorum wrightii, Ariz. 
Perhaps some of the larger spored forms (on B. oligostachya 
for instance) deserve specific recognition. The writer is also 
somewhat in doubt about the specific position of the specimens 
issued by Griffiths in his West American Fungi on Pappophorum 
wrightii and Bouteloua polystachya as in both of these cases 
the sori are in the aborted inflorescence instead of on the leaves. 
USTILAGO BUCHLOES Ell. & Tr. —Host: Buchloe 
dactyloides, Neb., N. Mex. (type). , 
Further study may possibly show this to be the same as the 
last species. 
USTILAGO PUSTULATA Tr. & Earle.—Hosts: Panicum 
proliferum, la., Ill., Kans., Miss, (type) ; P. virgatum, Tex. 
USTILAGO SPHAEROGENA Burr.—Host: Panicum 
crus-galli. Conn., Ia., Ill. (type), Neb. 
USTILAGO CRUS-GALLI Tr. & Earle.—Ustilago crus- 
galli Tr. & Earle, Bull. Torr. Bot. Club 22:175. 1895. Cintrac- 
tia seymouriana Magn. Ber. Deut. Bot. Ges. 14:217. 1896. Cin- 
tractia crus-galli Magn., Ber. Deut. Bot. Ges. 14:392. 1896. 
Host: Panicum crus-galli, Ark., Ill., Mass., Minn., Ore., 
S. Dak., Utah (type), Wash. 
Magnus has placed this species under the genus Cintractia 
because of the method of spore formation. As considered here
