102 TWENTY-FIFTH REPORT ON THE STATE MUSEUM. 
dotted by the numerous slightly prominent stellate ostiola; peri- 
thecia crowded in a single layer,elliptical, black; asci long, con- 
taining many spores; spores sausage-shaped, yellowish in the mass, 
.0002' long. 
Dead branches of birch trees, Betula lutca, in woods. Greig. 
September. 
This species belongs to the subgenus Diatrypella and may be 
readily known by the green stroma. Externally it resembles 
Melanconis elliptica. 
Evrypa Lata Pers. 
Decaying wood. Greenbush and Castleton. May and June. 
Dorniwea Trirrotu Lr. 
Leaves of clover. Buffalo. Clinton. Sterile. 
DorumEa KALMLE n. sp. 
Thin, effuse, investing the branches, black, shining, brownish 
within ; cells small, whitish within ; asci linear; spores uniseriate, 
uniseptate, constricted, subhyaline, .0004—.0005' long, half as broad, 
the cells generally nucleate and unequal. 
Branches of Kalmia angustifolia. Sandlake. September. 
This plant forms a black crust which entirely surrounds the 
smaller branches, and which, in fertile specimens, is seen by care- 
ful inspection to be minutely dotted with black points or ostiola. 
Within it has the appearance of half charred wood. It kills the 
branches attacked. A form of this plant was found in June, desti- 
tute of asci but having oblong, simple, spore-like bodies, .0008' long. 
MELANCONIS ELLIPTICA 7. Sp. 
Stroma transversely erumpent, elliptical, prominent, seated on 
and discoloring the inner bark, black on the surface, having an 
olivaceous tinge within ; perithecia small, immersed in the basal 
part of the stroma, subglobose, black ; ostiola few, papillate, some- 
times surrounded by an impressed line; spores crowded or biseriate 
above, colored, elliptical-oblong, five-septate, .0011—.0013' long, 
.0005' broad. 
Bark of dead birches, Betula populifolia. Center. November 
and April. 
This species is apparently related to JZ lanciformis, but the 
spores are smaller. The aperture in the epidermis is acute at each 
end. 
VaLsA AMBIENS £7,
