Apothecia scattered, sessile, at first nearly globose, expanding 

 and becoming discoid, reaching a diameter of 0.5-1 mm., ex- 

 ternally pale yellowish-green, coarsely furfuraceous; hymenium 

 at first concave, becoming plane or slightly convex, yellowish- 

 green, becoming darker as the plants mature on account of the 

 dark-colored spores, roughened by the protruding asci; asci 

 clavate, reaching a length of 75 jx and a diameter of 12-15 ix, 8- 

 spored; spores 1-seriate, or finally becoming 2-seriate or irregu- 

 larly crowded, ellipsoid with the ends quite strongly narrowed, 

 hyaline, then violet, finally pale-brown, becoming sculptured, 

 7-8 X 12-14 /x; spore-sculpturing consisting of anastomosing 

 ridges or crevices which are mostly longitudinal; paraphyses very 

 slender, slightly enlarged above. 



On dung of dogs and birds. 



Type locality: Great Britain. 



Distribution: New York; also in Europe. 



8. Ascobolus candidus Schrot. Krypt.-Fl. Schles. 3^: 55. 1893. 

 Apothecia scattered, roundish, becoming subdiscoid, entirely 



pallid-white; hymenium becoming slightly convex, finally dotted 

 over with the protruding asci and becoming darker with age; 

 the excipular cells irregular and reaching a diameter of 12-15 /x; 

 asci clavate, gradually tapering below into a stem-like base, 

 reaching a length of 100-150 /x and a diameter of 20 /i, 8-spored; 

 spores 1-seriate, 2-seriate or irregularly disposed, ellipsoid, be- 

 coming pale-violet, later pale-brown, 8-10 X 13-16 /x, becoming 

 sculptured; spore-sculpturing consisting of minute warts; pa- 

 raphyses strongly enlarged above, reaching a diameter of about 

 4 /x at their apices, hyaline.
