Genus I. Mollisia Karst. Mycol. Fenn. i 1187. 1871. 

 Type species, Mollisia cinerea (Batsch.) Karst. 



Mycelium within the substratum. Apothecia waxy, sessile, 

 becoming" plane, sometimes lobed, small, glabrous, superficial or 

 suberumpent, exterior dark. Paraphyses filiform, somewhat 

 stout, septate only at the base. Asci clavate or cylindrico-clavate. 

 Spores 4-8, usually simple, rarely two-celled, hyaline, ellipsoid, 

 oblong, or fusiform, often granular or minutely guttulate.

 form. Asci elongate, cylindrico-clavate often somewhat acute 

 at the ends. Spores 8, oblong, ovate, cylindrical or fusiform,
