REPORT OF STATE BOTANIST, 1897 2 Q 5 
Exoascus unilateralis n. up. 
Spots mostly suborbicular, convex above, concave below, some¬ 
times confluent and irregular, discolored, either paler or darker than 
the surrounding tissues; asci epiphyllous, subcylindric, sometimes 
a little contracted just above the basal cell, .0016 to .002 in. long, 
.0005 to .0006 broad, the stalk cell .0005 to .0006 in. broad and 
nearly as long; spores commonly 8, globose or broadly elliptic, 
.00024 to .0003 in. long, .0002 to .00024 broad. 
Living leaves of choke cherry. Primus Virginiana. Evans Mills, 
Jefferson county and North Elba, Essex county. June. 
This species is allied to Exoascus deformans, from which it may 
be distinguished by its rather larger asci and spores and by its 
general habit. The invaded leaves are less distorted, even when the 
spots are' large and occupy much of their surface, and the fungus, 
so far as I have seen, occupies the upper surface only. This at 
length becomes slightly whitened by the effusion of the spores. 
Generally there are from one to three spots on a leaf. 
Hypocrea aurantiaca n. up. 
Perithecia minute, compactly crowded forming a continuous 
stratum or rarely scattered and involved in an orange colored to- 
mentum, orange colored, the ostiola slightly darker; asci slender, 
cylindric, .0025 to .003 in. long, .00016 broad; spore cells sub- 
globose, .00012 broad. 
On Poly poms chioneus. Gansevoort. July. 
This fungus appears to have been included by Mr Ellis in Hy¬ 
pocrea pallida, with which it agrees in spore characters, but from 
which it differs so greatly in its formation of a continuous crust and 
in the orange color of the perithecia and tomentum that it seems to 
me to merit separation as a distinct species. 
Peziza odorata P/c. 
Damp ground. Gansevoort and North Elba. July and August.
