No. 115.] . 69 
uniseptate, often slightly curved, .0009 to .0011 inch long, .00016 
broad. 
Dead leaves of alder, Alnus viridis. Mt. Marcy. June. The 
The spores are narrowed toward one end and septate in the middle. 
The species is evidently distinct from S. Alnz viridis in its larger 
exposed perithecia, in the shape of its spores and in wanting a 
dematiaceous stroma. Apparently the same species was found 
near Elizabethtown, but without fruit. 
SPHZZERELLA PONTEDERIZA, N. sp. 
Spots rather large, six to ten lines long, oblong or elliptical, 
sometimes confluent, brown above, blackish brown or grayish 
brown below; perithecia minute, .003 inch broad, hypophyllous, 
black; asci oblong or subfusiform, .002 to .0025 inch long, .0005 
broad; spores crowded or biseriate, oblong-clavate, uniseptate, 
sometimes quadrinucleate, .0006 to .0008 inch long, .0002 to .00025 
broad. 
Languishing leaves of pickerel weed, Pontederia cordata. 
Whitehall, Washington county. September. 
Apparently related to S. Caladu, but with longer spores and 
different spots. 
SPHZERELLA PINSAPO, Thum. 
Fallen leaves of arbor-vite. Port Henry. June. 
DIAPORTHE SULPHUREA, Fckl. 
Dead stems and branches of hazelnut, Corylus rostrata. Ganse- 
voort. September. 
This species is easily recognized by the beautiful yellow spurious 
stroma that extends everywhere under the epidermis of the 
affected branches. 
DIAPORTHE (CHOROSTATE) FARINOSA, N. sp. 
Stroma somewhat pulverulent or mealy, dull buft color, formed 
of the slightly changed inner bark, erumpent in a minute slightly 
exserted disk ; perithecia valsoid, irregularly circinating, generally 
four to ten in a circle, the clusters subconfluent, ostiola black, 
dotting the prominent pulverulent buff colored or at length 
brownish disk; asci subcylindrical, .0024 to .003 inch long, .00035 
to .0004 broad ; spores crowded or biseriate, oblong or subfusitorm,
