them. Spores simple or compound, surrounded by a hyaline gelatinous 
envelope or ornamented with hyaline gelatinous apiculi, usually dark- 
colored. Plants entirely saprophytic and generally growing on dung. 
Spores simple (except Pleurage zygospora ). 
Ascus perforate; spores partially or entirely surrounded by a hyaline, gelatinous 
envelope. 1. Fimetaria. 
Ascus not perforate, but opening by the breaking off of the inelastic, ascus apex; 
spores ornamented by secondary, gelatinous appendages, with or without primary ones.

1. Fimetaria tetraspora Sp. Nov. 
Mycelium more or less superficial, white, sparingly branched, septate, 
with hyphae 2-3 mic. in diameter; perithecia scattered or aggregate, 
sunken, globose to ovate-globose, with a projecting, papilliform beak, 
350-440x305-395 mic., black, opaque, thin, membranous; paraphyses simple, 
stout, somewhat ventricose below and tapering upward, not numerous, 
not mixed with the asci but surrounding all the asci as a whole, equaling 
or longer than the asci, septate, persistent; asci cylindrical, contracted 
below into a straight or crooked stipe, 100-145x13-17.5 mic., 4-spored, 
evanescent; spores 1-seriate, oblique or erect, ranging from hyaline when 
young through olivaceous to dark-brown and opaque, ellipsoid, rounded 
above, with aminute hyaline apiculus at the lower end which becomes 
brown and opaquein some spores making the spore sharp-pointed, 
20-27x13-20 mic., with a narrow hyaline envelope swelling but slightly in 
water except that of the upper end of the apical spore which becomes 
much rounded out.
