There is some doubt as to the identity of Oospora Candida, but 
'from the description it is probably a variety or a young stage of 
Oospora fructigena {Torula fmctigena Pers.). This latter spe- 
cies is given as the second species under the genus, and, in case 
the former is not considered sufficiently clear to establish the 
genus, there can be 'no doubt as to the second species.

Oidium fructigenum Link Sp. PI. 6': 122. 1824. 
Pulvinate, sometimes confluent, white at first, then pink to 
brown; mycelium fasciculate, thin, septate; sporophores erect 
or suberect, simple or branched, dividing into chains of spores ; 
spores ovoid, obovoid, or lemon-shaped, hyaline or colored, 
10-12 X 16-25 fX. 
On various fruits, as apple, peach, plum. 
Specimens examined: Canada, Thaxter; New York, Shear; 
Ohio; Pennsylvania, Sumstine ; South Carolina, Ravenel. 
This fungus is known as the “brown rot” of fruit. It has 
been investigated by various students and its life history is fairly 
well known. It might more properly be treated under the perfect 
stage, Sclerotinia fructigena (Pers.) Schroet. 
2. Oospora cinerea (Bon.) 
Monilia cinerea Bon. Handb. Mykol. 76. 1851. 
Pulvinate or effused, gray or gray-brown ; mycelium branched,
