SPHACELOTHECA PASPALI-NOTATI (Henn.) Clint, 
n. sp.— Ustilago paspali-notati Flenn., n. sp. in Herb. Holway. 
Sori in the inflorescence, linear, about 4-6 cm in length, 
with evident false membrane gradually flaking away from apex 
and exposing reddish brown dusty spore mass surrounding evi¬ 
dent often forked columella; sterile cells hyaline, with those of 
the membrane adhering rather firmly, with inner loose ones in 
roundish clusters, usually larger than the spores; spores light 
reddish brown, ovoid to spherical or slightly angled, apparently 
smooth but very minutely verruclose, 7-10 in length. 
Host: Paspalum notatum, Mex. (type). 
This species is very near Sphacelotheca ischaemi, in fact is 
scarcely to be distinguished from the verruculose forms of that 
species, though it has a more luxuriant sorus and different host. 
For this reason there may be some question if it is entitled to the 
specific rank given it by Hennings.
