DIATRYPE PROMINENS Hove. 
Bark of Platanus occidentalis. Yonkers. Howe. 
DIATRYPE ANOMALA 2. Sp. 
Pustules prominent, subrotund or elliptical, 1-2” in di- 
ameter, erumpent, penetrating the wood, generally with a 
thin black crust beneath and around them, the disk convex 
or slightly depressed, rough, brown or black, sometimes 
whitish-pulverulent; perithecia crowded, deeply imbedded 
in the stroma, often elongated ; ostiola scattered or crowded, 
convex, often radiate-sulcate, black ; asci short, broad, fir- 
gacious ; spores crowded, elliptical, simple, often with a 
nucleus at each end, colorless, .0003’—00035’ long. 
Stems of hazel bushes living or dead. Albany. May. 
The pustules sometimes appear in long lines or series. 
The peculiar and anomalous character of this species is 
found in its unusual spores and in its attacking living stems. 
MELANCONIS BICORNIS Cooke. 
Perithecia circinating, five to seven, seated beneath the 
epidermis which is but slightly elevated ; ostiola short, con- 
vergent, just piercing the epidermis, with a regular orifice ; 
spores expelled when mature, blackening the matrix round 
the ostiola, fasciculate, obtusely fusiform, straight or curved, 
triseptate, brown, .0026’-.0033’ long, scarcely constricted, 
ultimate cells smallest, each extremity tapering into a hya- 
line at first straight then curved or flexuous cornute append- 
age, one-half to one-third the length of the spore. 
Bark of Platanus occidentalis. La Salle. Clinton. 
Greenbush. March and May. 
Allied to Melanconis Berkelei Tul., but distinct. When 
the epidermis is torn away, the perithecia come off with it. 
They are slightly whitish-floccose or tomentose above. 
VALSA PRUNASTRI F7. 
Dead branches of plum or cherry. Greenbush. June. 
VALSA RUBI %. sp. 
Perithecia crowded, irregular, black, white within, form- 
ing a small pustule which is covered by the whitened epi- 
dermis ; ostiola crowded, piercing and generally obliterating
