CLINTON: NORTH AMERICAN USTILAGINEAE. 
461 
Sori in leaves, forming thin roundish or angular reddish yellow 
spots on upper side but more conspicuous beneath by the whitish 
growth of conidia (rarely epiphyllous), about 1-6 mm. in length ; 
spores yellowish tinted when young but often reddish yellow with 
age, chiefly subspherical or spherical, though occasionally more elon¬ 
gated or irregular, thick walled, epispore usually evident and some¬ 
times wrinkled or loosely investing endospore, 11-16 fx in length ; 
conidia apparently of two types, either long fusiform, often curved, 
35-45 fx x 2.5-3 /x or short fusiform, often curved near tip, 15-20 fx 
x 2.5-3.5 /x , usually disappearing through germination. 
Hosts : Anemone nemorosct, Wise.; Ranunculus Pennsylvania^, 
Wise. 
This species has been recognized only recently in America. Davis 
collected both hosts in Wisconsin. It differs from Entyloma Thal- 
ictri, apparently, in its larger, more regular spores with somewhat 
thicker walls. The form on Anemone nemorosa was originally re¬ 
ported under the latter species. Ward and Brefeld have described 
the germination. Literature : 20, 194.

Sori in leaves, small, angular, limited by veins, scattered or often 
abundant and somewhat confluent, showing above as reddish brown 
discolorations and beneath as more evident whitish areas often with 
a dense conidial outgrowth ; spores hyaline to yellowish, chiefly sub- 
spherical or spherical, thin walled, smooth, 8-12 fx in diameter; co¬ 
nidia (with mycelial outgrowth) forming a conspicuous hvpophyllous 
mat, subclavate or fusoid, often adhering in pairs, 12-24 /x x 3-5 fx. 
Host: Menispermum Canadense , la., Ill., Ivans., Minn., Mo., N. 
Dak., Wise. (type). 
This species usually has a dense white hvpophyllous growth that 
is largely composed of mycelial threads. It is a species so far 
reported only from the region of the Mississippi valley though it 
probably occurs elsewhere. The germination of the spores has 
not been described. Literature: 54.
