spores are shed, becoming glued over the adjacent parts. When 
dry the spores are very firmly agglutinated in the sorus.

CINTRACTIA AXICOLA var. MINOR Clint, n. var. — 
Sori and spores as in the species 'except latter smaller, chiefly 10- 
13/i in length. 
Host: Cyperus grayii, N. Y. 
This variety is based on the specimen issued in Ell. and Ev. 
N. A. F. no. 2423 as Ustilago (Cintractia) axicola Berk. Be¬ 
sides having a different host it differs from this species in having 
smaller spores. It sometimes occurs at the base of the spikelets 
forming a conspicuous smutty mass. In some respects it agrees 
with a species Spegazzini has described from South America as 
Cintractia peribebuyensis on Cyperus.

Sori in ovaries, ovoid to subspherical, chiefly 3-6 mm. in 
length, covered by an evident whitish false membrane that rup¬ 
tures irregularly from the apex disclosing semi-agglutinated black 
spore mass; sterile cells hyaline, chiefly subspherical, often semi- 
gelatinized ; spores dark reddish brown, often subopaque, with 
irregular lighter areas, somewhat compressed laterally and there-
