what darker, minute, sessile. Paraphyses slender, bent at the 

 ends, not branched. Asci operculate, broadly clavate, hyaline. 

 Spores hyaline, then i)urj)lc, then l)rown, oval or somewhat fusi- 

 form, ejected in a mass surrounded by a gelatinous envelope, not 

 tilling the ascus when mature, 12 mic. long and 5 mic. wide. 



Grown on old cow dung in the laboratory.

1\\-pe species, Ascophanus subfuscus ( Cnjiian ) Bond. 



Mycelium mostly in the substratum biU more ctr less alnm- 

 dant beneath the apothecia. Apothecia fleshy or Heshy-gelatinouri, 

 sessile, concave then plane or convex, small, glabrous or pruinose, 

 somewhat pyriform. Paraphyses simple or branched, septate, 

 slender, often granular, hyaline jr colored, e(|ual in length with 

 the asci, apices usually clavate. Asci broadly clavate, rarely ob- 

 long-ovate, hyaline or slightly tinted, attenuated at the base, 

 prominent as crystalline jjapillae en the liymenium, with a con- 

 spicuous round, fjften recurved operculum. Spores 8 or 16, 

 elliptic or oblong-elliptic, when immature surrounded singly by 

 a hyaline gelatinous envelope, smooth or rare minutelv punc- 

 tate, hyaline or very slightly tinted, the nucleus conspicuous. 



Commonly found on dung but also on decaying plant ma- 

 terial. 



The genus may be distinguished from Ascol)olus and Sacco- 

 bolus by the spores which are always hyaline although some- 

 times by refraction they appear greenish or roseate, and from 

 Lasiobolus by the less hairy exterior of the aprjthecia. A single 

 species has 16 spores.
