or sometimes confined to a lateral half. The leaf or half leaf be¬ 
comes pale yellow and finally dead and brown. The pycnidia are 
somewhat flattened, about 100x75/a and extend through to the 
epidermis of the upper leaf surface. There are no pycnidia on the 
stems. The sporules are continuous, slightly curved, acute, 
30-60x1I have labeled this forma asprelli.

Of a collection on Salix lucida the following notes were made: 
Spots angular to orbicular, oblivaceous to brown, becoming cinere¬ 
ous with a dark border, paler below, 1-3 mm. in diameter; acervuli 
mostly hypophyllous, small, scattered, subcuticular; sporules min¬ 
ute, hyaline, l-Sxl-l^/x abstricted from hyaline, vertical, parallel 
hyphae, 15~20xlju,. Cadott, Wisconsin, September 19, 1922. This 
seems to be a microconidial state but for the purpose of filing I 
have labeled it Gloeosporium egenmn n. sp.

(P. R. Jones) 
Oolletotrichum violarum n. sp. 
Spots circular to angular or irregular in outline, arid with a 
slightly raised margin, l-~6 mm. in diameter, sometimes confluent, 
often lacerate; acervuli amphigenous, small, black; setae marginal, 
black, variable in size (up to 165x5ja) and number, acute; sporules 
hyaline, oblong, somewhat curved or at least inequilateral, acute 
at each end, continuous, 18-20x3ju,. On leaves of Viola scahrius- 
cula, Spring Green, Wisconsin, July 3, 1922. I have not seen a 
specimen of the fungus on Viola rotundifolia collected by G. W. 
Clinton and referred to as a variety of Vermicularia eoncentrica

Report, p, 48. 
Septogloeum subnudum n. sp. 
Spots suborbicular, reddish brown with an olivaceous border, 
2-5 mm. in diameter, becoming confluent; acervuli few, small, 
inconspicuous, epiphyllous, subcuticular; sporules hyaline, fusoid- 
oblong, straight, inequilateral or usually curved, 20-40x7-11/1., with 
a septum toward each end. On Smilax kerhacea^ Sauk City, Wis¬
