180 FUNGUS-FLORA. 



PYPAPOBIUS. Bond, (emended.) (figs. 34, 35, p. 156.) 



Ascophore minute, sessile, at first subglobose, the disc 

 expanding until plane or slightly convex, fleshy, glabrous or 

 ciliated at the margin; excipulum parenchymatous, cortical 

 cells irregularly polygonal, large : asci broadly cylindric- 

 clavate, dehiscing by an apical operculum, protruding above 

 the level of the disc at maturity, 1 G-many-spored ; spores 

 hyaline, smooth, elongated, in some species aggregated in a 

 cluster near the top of the ascus before dehiscence ; para- 

 physes present.

Ascozonus, Kenny. 



Distinguished at once by the asci containing 10 or more 

 hyaline spores. 



* Spores not more than 32 in an ascus.

 viii. n. 2243. (fig. 38, p. 156.) 



Ascophores scattered or gregarious, cylindrical or sub- 

 globose at first, then expanding until the disc is quite plane, 

 white, or with a very slight grey or rosy tinge, delicately 

 pruinose on the outside, f-1 mm. across ; excipulum paren- 

 chjnnatous ; asci broadly cylinclric-clavate, pedicel short, 

 stout, often oblique, 32-spored, projecting prominently 

 above the level of the disc ; spores ellijjtical, ends somewhat 

 pointed, smooth, hyaline, wall rather thick, 26-32 x 

 14-16 /x ; paraphyses septate, hyaline, slender, often branched 

 from near the base, tips onl3 T very slightly thickened, longer 

 than the asci.

On dung of horse, cow, sheep, and dog. 



Distinguished among species having more than 8 spores in 

 an ascus, by the large asci, which project for about half
