uniseptate, often slightly curved, .0009 to .0011 inch long, .00016 

 broad. 



Dead leaves of alder, Almts viridis. Mt. Marcy. June. The 

 spores are narrowed toward one end and septate in the middle. 

 The species is evidently distinct from S. Alni 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. 



SPH^RELLA PONTEDERI^, 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 .oooS inch long, .0002 to .00025 

 broad. 



Languishing leaves of pickerel weed, Poiitederia cordata. White- 

 hall, Washington county. September. 



Apparently related to 5. Caladii, but with longer spores and 

 different spots. 



SPHiERELLA PINSAPO, Thum. 



Fallen leaves of arbor-vitae. 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 buff colored, fonned 

 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 subfusiform, uniseptate, 

 generally quadrinucleate, .0006 to .0008 inch long, .00016 to .0002 

 broad.
