Perithecia small, about J u. cliani.. buried in the inner bark in sub- 

 circinate groups of 8-12. covered above by a thin, black crust lyinn 1 

 just beneath the epidermis. Ostiola slightly convergent, rising sepa- 

 rately through the overlying crust and raising and rupturing the 

 epidermis, short-cylindrical, subcompressed or otherwise irregular.

Perithecia in subcircinate clusters of 3-6 (occasionally only on- 

 buried in the inner bark, their bases peni-miting to the subjacent 

 wood, lar-v i , ; -l mm.), collapsing below, abruptly contracted above 

 into short necks terminating in subtubercular, quadrisulcate-cleft 

 ostiola, erumpent (but not strongly prominent) through the thin. 

 black, superficial, convex crust that covers the stroma. The substance 

 of the stroma consists entirely (except the black, circumscribing layer) 

 of the bleached substance of the bark. Stroma elliptical, 2-5 mm. 

 diam., with a distinct, black, circumscribing line, which does not pene- 

 trate deeply into the wood. Asci oblong-lanceolate, about 100 x 12 t u. 

 Sporidia biseriate, hyaline, oblong. 20-22 x 7-8 //. uniseptatc and con- 

 stricted, each cell with a large nucleus.
