hypothecium pallid, outer cells of the cup brownish. Paraphyses 

 filiform, filled with granules. Asci cylindrico-clavate. Spores 

 fusiform, 7-10 mic. long and 3-4 mic. wide, guttulate. 



Karsten says the spores are ovoid-oblong or somewhat need- 

 le-like and 4-7 mic. long and 1.5-2 mic. wide. 



Growing on old wood.

Alycelium usually entirely within the substratum. Apothe- 

 cia subgelatinous, becoming more or less plane, sessile or some- 

 times very shortly stipitate, glabrous, small, reddish or yellowish, 

 somewhat translucent. Paraphyses simple or branched at the 

 base, the ends clavate, globose, flattened or covered with a muci- 

 laginous epithecium. Asci cylindrico-clavate. Spores 8, small, 

 ovoid, filiform, fusiform or spherical, simple. 



Growing on wood or other decaying plant material.
