Apothecia gregarious or crowded, often forming congested 

 masses of considerable extent, at first closed, expanding and 

 becoming discoid or short-cylindric, rarely reaching a diameter 

 of 1 mm., externally clothed with very conspicuous hairs; 

 hymenium concave, plane or slightly convex, roughened by the 

 protruding asci, the color varying from almost hyaline to pale- 

 yellow or orange; hairs swollen near the base, where they reach a 

 diameter of 30-35 /x, tapering above into a sharp-pointed apex, 

 reaching a length of 375 yu, thick-walled, non-septate, hyaline or 

 faintly yellowish; asci cylindric or subcylindric above, tapering 

 rather abruptly below into a stem-like base, reaching a length 

 of 200 ju and a diameter of 20-24 m; spores 1-seriate or irregularly 

 crowded, smooth, hyaline, or slightly yellowish, ellipsoid, 12-14 

 X 20-24 m; paraphyses slender, septate, slightly enlarged above,
