plane, becoming convex, at first similar in color to the outside 

 of the apothecium, becoming almost entirely black; the com- 

 ponent cells of the excipulum roundish or irregularly angular, 

 reaching a diameter of 25 fx, the walls hyaline to pale-yellowish; 

 asci clavate, strongly swollen above, tapering rather abruptly 

 below into a short stem-like base, reaching a length of 300-350 fx 

 and a diameter of 40 /z, 8-spored; spores 2-seriate or irregularly 

 crowded, ellipsoid, with the ends rather strongly narrowed, 

 hyaline, becoming violet, finally pale-brown, becoming sculptured, 

 12-13 X 23-38 yu; spore-sculpturing taking the form of longi- 

 tudinally or irregularly disposed, anastomosing ridges or crevices; 

 paraphyses slender, about 2 /x in diameter, slightly enlarged 

 above.

Apothecia gregarious or densely crowded, sessile, subglobose, 

 externally yellowish, smooth, reaching a diameter of 0.2-0.4 mm. ; 

 hymenium convex, yellowish-brown, finally almost black; asci 

 cylindric or subcylindric to clavate, tapering below rather 

 gradually into a long stem-like base, reaching a length of 180- 

 200 fx and a diameter of 30-33 /x, when mature often stretching 

 to 300 or 400 M long; spores 2-seriate or irregularly disposed, 

 ellipsoid, at first hyaline, then brown, for a long time smooth, 

 becoming sculptured, 12-16 X 24-33 ijl; spore-sculpturing con- 

 sisting of minute warts and reticulations, the reticulations 

 consisting of light lines which give rise to irregular or hexagonal 

 meshes, the meshes ranging from 2 to 5 /x in diameter; paraphyses 

 filiform, septate, about 2.5 /x thick, a little enlarged above, 

 embedded in a yellow mucilaginous substance.
