Apothecia crowded or confluent, spreading, convex, 1-2 mm. 

 broad, fleshy, orange yellow, sessile. Hymenium pale salmon- 

 pink, hypothecium darker, central part of the cup colorless. 

 Paraphyses filiform, rather stout, sometimes appearing pseudo- 

 septate, hyaline but pinkish in mass. Asci cylindrical, wall 

 thickened at the ends. Spores uniseriate, hyaline, 10-12 mic. 

 long and 6-7 mic. wide, oval, smooth. 



Growing on ashes and burnt wood. Probably common. 

 Spring and summer.

Mycelium mostly in the substratum. Apothecia fleshy, su- 

 perficial or somewhat immersed, sessile or nearly so, exterior 

 smooth, scaly, or hairy. Exciple when present, and hypothecium 

 of similar structure and usually pseudo-parenchymatous. Ex- 

 ciple often wanting or poorly developed. Asci emergent.

 Mycelium within the substratum. Apothecia fleshy or 

 fleshy-gelatinous, sessile or rarely substipitate, at first concave, 

 becoming either plane or convex, small glabrous or scaly, rarely 

 hairy. Hymenium more or less gelatinous, hyaline or colored. 

 Paraphyses numerous, slender, scarcely enlarged upwards, at first 

 longer than the asci, simple or divided at the base, septate. 

 Asci clavate or cylindrico-clavate, large, attenuated at the base, 

 the apex broad, the operculum round and often drawn up to a
