 hypophyllous, immersed, about 100 // diam., thin-membranaceous, the 

 apex perforating tlie epidermis. Asci clavato, very short-pedicellate, 

 8-S]iored, 50-70 \ 9-11 //., with thick, cylindrical, septate paraphyses. 

 Sporidisi biseriate (rarely uniseriate), oblong, inequilateral, attenuated

ticular, J-J mm. diam. Asci cylindrical, 100-112x10-12 /;., with 

 abundant, linear paraphyses. Sporidia uniseriate, hyaline at first and 

 3-nucleate, soon becoming dark brown and uniseptate, 18-2()x 5-6 //, 

 surrounded at first with a hyaline envelope. The sporidia are much 

 like those of Anthostomella leucobasis, E. & M., only longer and uni- 

 -cptate, and the perithecia are larger and more prominent.

Perithecia minute, punotiform, subglobose, covered by the epi- 

 dermis, which is pierced l)y the scarcely papillate ostiola. Asci 

 cylindrical, 55-80x7^-10 //, with filiform paraphyses. Sporidia ob- 

 long or elliptical, uniseriate, uniseptate, not at all, or but slightly con-

Perithecia scattered, covered, but prominent, small, smooth, at 

 length collapsed and flattened. Ostiolum minute, erumpent. Asci 

 cylindrical, 75-100x7-8 //.. with branching paraphyses, 8-spored. 

 Sporidia uniseriate, rarely subbiseriate, biconic-elliptical, uniseptate. 

 constricted, colored, straight or curved, 2-nucleate, 8-11 x 6 /^. Very 

 variable, especially in the size of the sporidia. A form occurs (on 

 I) ramble steins) with the asci mostly tetrasporous.
