USTILAGO PANICI-PROLIFERI Henn.—Host: Pani- 
cum proliferum var. acuminatum, Mex. (type). 
USTILAGO PANICI-LEUCOPHAEI Bref.—Ustilago in-

USTILAGO ULEI Henn.—Host: Chloris submutica, Mex. 
USTILAGO CHLORIDICOLA Henn.—Host: Chloris sp., 
Calif, (type). 
USTILAGO TILLANDSIAE Patters, n. sp.—Sori destroy¬ 
ing inner flower parts, protected by enclosing bracts and perianth, 
forming an irregular dusty black spore mass about 1-3 cm. in 
length; spores olive brown, chiefly ovoid to spherical, thin walled, 
more or less collapsed or hemispherically cupped, smooth or with 
brittle epispore breaking up into thin polygonal areas, 7-13 11 in 
length. 
Hosts: Tillandsia leiboldiana, Mex.; Tillandsia sp., Costa 
Rica (type). 
The writer first learned of this species through Mrs. Flora 
W. Patterson of the Department of Agriculture and later on 
searching in the Gray Herbarium found it on specimens from 
Mexico. It is somewhat questionable whether the species is a 
true Ustilago or some Hyphomycete having the appearance of 
a smut, though it is more probably the former. A study of the 
method of spore production and germination may be necessary 
to determine its true position.
