ASCOMYCES RUBROBRUNNEVUS, N. sp. 
Spots definite, variable, small and suborbicular or large and 
irregular, sometimes confluent, usually concave above, convex 
below, dull reddish-brown above, paler below; asci oblong, trun- 
cate at the apex, .002 to .003 inch long, .0006 to .0009 broad ; 
spores minute, subelliptical, .00012 to .00016 inch long, .0006 to 
.0008 broad. 
Living leaves of red oak, Quercus rubra. Sandlake. September. 
In some respects this approaches A. alutarius, from which the 
color of the spots, larger asci and different shape of the spores will 
distinguish it. 
ERYSIPHE HORRIDULA, Lev. 
Abundant on corn gromwell, Lethospermum arvense. Port 
Henry. June. 
Our specimens were too young when collected to show the spore 
characters, and are to this extent doubtful. 
CALOSPHZERIA CILIATULA, Karst. 
Dead trunks and branches of white birch, Betula popu 
Menands. September. 
VALSA THUJA, N. sp. 
Pustules scattered, slightly prominent, closely covered by the 
epidermis ; perithecia nestling in the inner bark, subcircinate, five 
to ten in a pustule; asci oblong-clavate, .0014 to .0016 inch long ; 
spores allantoid, .0004 to .6005 inch long, .00008 to .0001 broad. 
Dead*branches of arbor vite, Thuja occidentalis. Elizabeth- 
towp. September. 
VALSA EXUDANS, N. sp. 
Perithecia collected in a cortical stroma, thin, crowded, angular, 
closely covered by the pustulately elevated, irregularly ruptured 
epidermis, ostiola obscure or concealed beneath the defiled epider- 
mis; asci very slender, cylindrical, .0016 inch long, .00016 broad ; 
spores minute, oblong, straight, colored, .0002 inch long, oozing 
out and staining the surface of the matrix. 
’ Dead bark of alders, Alnus incana. Elizabethtown. September. 
This is an anomalous species and does not agree well with the 
generic characters. The straight, colored and oozing spores are 
unusual and peculiar features.
