stout, septate, enlarged near the apex and filled with reddish 

 granules. Asci clavate, very broad. Spores 8, smooth, irregu- 

 larly arranged, oblong-elliptic, 18 mic. long and 10 mic. wide. 

 Grown on cow and horse dung in the laboratory. 



Genus IV. Lasiobolus Sacc. Bot. Cent. 18:220 [8]. 1884. 

 Type species, Lasiobolus papillatus (Bond.) Sacc. 



Mycelium seldom visible. Apothecia fleshy, sessile, becom- 

 ing plane or convex, minute, externally covered with sharp 

 pointed hairs. Paraphyses simple or branched, septate, slender 

 or somewhat stout, often granular, equaling the asci in length, 

 apices often clavate. Asci clavate or cylindrico-clavate, hyaline, 

 tapering slightly at the base. Spores 8, elliptic or oblong-elliptic, 

 hyaline. 



Growing commonly on dung. 



The genus may be distinguished from Ascophanus by the 

 sharp pointed hairs which cover the exterior of the apothecia.

 exterior of cup having a number of bristle-like, septate, color- 

 less hairs. Hymenium, hypothecium and exciple brownish yel- 

 low. Paraphyses numerous, septate, granular, rather stout. 

 Asci cylindrico-clavate, operculate, hyaline. Spores oblong- 

 elliptic, smooth, hyaline, usually granular, 22 mic. long and 10 or

 the substratum. Apothecia fleshy-waxy, waxy, membranous, 

 cartilaginous or gelatinous, sessile or stipitate, exterior smooth
