 greenish-black, .1-.3 mm. in diameter, almost globose, opening 

 above and the spores emerging in a whitish, or pale-greenish mass 

 or cirrhus; conidiophores lining the cavity, hyaline, cylindric, 

 tapering to a tip, simple, or 1-3-septate; microconidia hyaline, 

 filiform, simple, strongly curved, ends rounded, 1-1.5 X 9-15 /x- 



Apothecia erumpent, single, or cespitose in clusters of two to 

 six, circular, or slightly undulated, sessile, narrowed below and 

 substipitate, .5-1.5 mm. in diameter, .5-1 mm. high, dark reddish- 

 brown to almost black; asci cylindric-clavate, short-stalked, 8- 

 spored, reaching a length of 75-100 jj. and a diameter of 14-16 ju; 

 spores ellipsoid, or ovoid, hyaline, becoming brownish, simple, or 

 1-3-septate, irregularly 2-seriate, 6-8 X 12-18 /i; paraphyses 

 hyaline, filiform, simple, or branched, 1.5-2 fx in diameter, the tips 

 swollen to 3 fx, forming a slight epithecium.

 six each, circular, or slightly undulate, sessile, narrowed below, 

 .3-.8 mm. in diameter, .2-4 mm. high, dark reddish-brown to 

 black, leathery to horny, softer when moist; hymenium concave, 

 becoming plane, or slightly convex, the margin slightly raised ; asci 

 cylindric-clavate, short-stalked, 8-spored, reaching a length of 

 70-100 /x and a diameter of 14-20 m; spores ellipsoid-fusiform, 

 hyahne, straight, or slightly curved, simple, or 1 -septate, irregu- 

 larly 2-seriate, 5-7.5 X 18-20 m; paraphyses hyaline, filiform,
