-\-Ascobolus astrofuscus Phil. & Plow, in Grev. 2: 18C. pi. 24. 



f. 1. 1874. 



Apothecia solitary or in groups, sessile, becoming plane, 

 edge crenulate, interior and exterior dark reddish-brown, ex- 

 terior scaly. Hymenium and outer cells of the cup brownish. 

 Paraphyses somewhat longer than the asci, simple or branched. 

 Asci narrowly clavate. Spores oblong-elliptic, 22 mic. long and 

 13 mic. wide, hyaline, then violet, then brown, minutely warty. 



Growing on the ground where fire had been and among 

 charcoal.

Genus II. Saccobolus Bond. Ann. Sci. Nat. 10:228. 1869. 

 Type species, Saccobolus kerverni (Cronan) Boud. 



Mycelium within the substratum. Apothecia fleshy, sessile, 

 somewhat concave, then becoming plane and convex, small, some- 

 what transparent, glabrous. Paraphyses numerous, slender, 

 septate, simple or branched, of the same length as the asci, the 

 apices clavate and often colored. Asci broad, short, attenuated 

 at the base, emergent, with triangular operculum. Spores 8, 

 usually elliptic, hyaline, then purple and finally brown, smooth, 

 if ridged, then transversely never longitudinally, large, enclosed 

 in a common hyaline gelatinous envelope. 



Growing on dung. 



The genus is easily distinguished from Ascobolus by the 

 smaller size of the apothecia, by the shorter, larger and less 

 prominent asci, by the shorter paraphyses, and by the gelatinous 

 envelope enclosing the spores. The hymenium becomes dotted 

 as in Ascobolus as the spores mature.
