 slightly irregular from mutual pressure, entirely black, reaching 

 a diameter of .5 mm.; hymenium slightly concave, bordered by a 

 slightly upturned margin, black; asci clavate, reaching a length 

 of 95-110 iJL and a diameter of 10-12 /x, 8-spored; spores long,

 of 45-60 M and a diameter of 2-3 m. 3-septate; paraphyses slender, 

 branched, hyaline, or subhyaline. 



The conidial stage accompanies the ascigerous and consists of
