 35-40 X 12 fi, with a hyaline apiculus at each end.

 at the septum, colored, 36^5 ii long. 



On decaying wood of Thuja occidentalism Adirondack Mts., New

As no mention is made of any asci, this, as far as the description

 Asci clavate or oblong. Sporidia clavate-oblong, uniseptate, some- 

 times with a gelatinous coat, 33 ii long. 



On old logs, mountains of New York. 



Nothing is said of the color of the sporidia, but Cooke (1. c.) 

 places this in AmpJdsphcBria, with species having brown, uniseptate

 12x3/<. 



Schweinitz also observes that often the ostiola of 2-3 perithecia 

 are, as it were, connate, united into a single ostiolum, round or vari-
