Apothecia gregarious or scattered, \'ery minute and scarcely 

 visible to the unaided eye, at first subglobose, then becoming 

 expanded and more or less discoid, at first white or whitish, 

 becoming dull-pallid or dirty-white, not usually exceeding 0.5 

 mm. in diameter; hymenium convex and roughened by the 

 strongly protruding asci; asci comparatively few to each plant 

 and very broad-clavate to subovoid, many-spored, the exact 

 number of the spores difiicult to make out with certainty, but 

 usually 64, entire ascus reaching a length of 90-100 /x and a 

 diameter of about 25 n, rather abruptly tapering below into a 

 short stem-like base; spores ellipsoid, crowded together in the 

 ascus with no apparent order, hyaline, often with one small oil- 

 drop or with none apparent, above 4-6 X 7-10 m; paraphyses 

 sparse, slender and very slightly thickened above.
