VALSELLA ADHERENS, Fckl. 
Corticated trunk and branches of white birch, va pagans 
Sandlake. September. 
In our plant the disk is often whitish or grayish trom the adhering 
remains of the epidermis; the perithecia are five to twelve in a 
pustule and the spores are colored in the mass. It is apparently a 
variety of the species and may be called var. Americana. 
VALSELLA LASCHII, Sacc. 
Dead whitened twigs of Acer spicatum. Port Henry. June. 
In our specimens the black stroma is apparent through the 
translucid epidermis, and the white disk, though small, is plainly 
seen by contrast. The asci are very broad, .6016 to .002 inch long, 
.0005 to .0006 broad. This form may be designated var. acerina. 
DIATRYPELLA QUERCINA, Nits. 
Dead branches of thorn, Crategus tomentosa. Elizabethtown. 
September. 
Although oceurring on thorn branches, there does not appear to 
be any good characters for separating this fungus from the species 
to which I have referred it. 
SPHAARELLA MINUTISSIMA, N. sp. 
Perithecia very numerous, occupying the whole lower surface of 
the leaf, very minute, .002 to .0025 inch broad, veiled by the epider- 
mis, black; asci oblong or slightly narrowed toward the apex, 
.0016 to .002 inch long, .0008 to .0004 broad; spores crowded, 
oblong, straight, obscurely septate in the middle, .0006 to .0007 
inch long, .00016 broad. 
Dead leaves of alder, Alnus incana. Adirondack mountains. 
June. 
The perithecia are scarcely visible to the naked eye. The 
affected leaves remain on the branches through the winter. They 
had not yet fallen in June. 
SPHZERELLA ANLICOLA, N. sp. 
Perithecia small, .0035 to .0045 inch broad, hypophyllous, clus- 
tered or scattered, naked, black ; asci oblong or subclavate, .002 to 
.0025 inch long, .0005 to .0006 broad; spores crowded, lanceolate,
