Hosts.—Festuca microstachya, Desv. (?) : eee asperi- 
folius, Nees and Meyen ; Sporobolus Vixit Vase 
HAB.—United States, Rocky Mountain region. 
Allied to Tilletia Caries, but distinguished by the spore-mass 
not being foetid, the larger spores, larger and more irregular 
reticulations, and border paler than the remainder of the spore. 
Specimens illustrating the species and its two synonyms enumer- 
d above were received from is. The specimen from the 
author called 7. fusca, agrees exactly with the original description 
of this species in Journ. Myc. iii. (1887), 55. On the other hand, 
further material «— A the name of Tilletia pee (Ellis 
and Everh., N. Amer. Fung. ser. 2, 1895, in ovary of Festuca 
microstachya, from Boise City, Idaho) does not at all agree with 
iagnosis of the species as quoted above, but has the epispore 
dene and minutely warted, and is identical with Tilletia mixta, 
The priority of the specific m. fusca turns on this name 
standing first in order on the same page where montana and 
asperi ifolia are also described.

Closely resembling Tilletia Caries in spore-structure ; the 
border is a little wider in the present species. Specimen from
