"Perithecia scattered, subglobose, black, rather prominent, with a 

 mammillate ostiolum, seated on the decayed leaves and soon becoming 

 superficial. Asci clavate. Sporidia cylindrical, slightly curved at 

 one or both ends, uniseptate (then probably triseptate), hyaline, 40-50 

 x 8 /i." 



On dead Sphagnum, Maine.

Notiz. ueber neue und Krit. Pyr. p. 10. 



Perithecia subglobose, covered, membranaceous or coriaceo-mem- 

 branaceous, black, with the ostiolum (typically papilliform) erumpent. 

 Asci clavate-cylindrical, paraphysate. Sporidia ovoid or oblong, con- 

 tinuous, hyaline or subhyaline. 



Differs from Lcestadia in the presence of paraphyses. The peri- 

 thecia are also for the most part larger and of firmer texture. Includ- 

 ed by Winter in the next Family.
