 spores ellipsoid, hyaline, smooth, 10 X 20 m; paraphyses filiform, 

 scarcely thickened above, longer than the asci.

Apothecia gregarious but not usually crowded, at first globose, 

 expanding and becoming discoid, w th the hymenium plane or a 

 little concave and the margin slightly elevated, externally dark

 black specks on the substratum, entire plant not exceeding 

 0.2-0.5 mm. in diameter; hymenium paler, reddish-brown; ex- 

 cipulum pseudoparenchymatous, the component cells 2-5 /x in 

 diameter; asci clavate, 7-10 X 50-70 m, tapering gradually below; 

 spores minute, usually 2-seriate or partially 2-seriate, ellipsoid, 

 smooth, perfectly hyaline, 4 X 6-7 m; paraphyses very slender 

 below, about 1 /x thick, abruptly expanding above into a sub- 

 globose head which is filled with golden-yellow coloring matter, 

 reaching a diameter of 7-8 /x.
