COPRINARIT. 345 



■^^ Stemflexuous, prumate at the apex. Psathyrella. 



777. A. caudatus Fr. — Pileus as much as 5 cent. (2 in.) broad 

 when flattened, date brown, membranaceous, very tender, conical 

 then campamilate, at length flattened, smooth, the sojnewhat gib- 

 bous disc even, otherwise pellucid-striate, not corrugated. Stem 

 7.5 cent. (3 in.) and more long, almost 4 mm. (2 lin.) thick, fis- 

 tulose, attenuatedyr^w tlie thickeiied and rooting base, very fragile, 

 curved, at length tortuous, undulated on the surface, white prui- 

 nate at the apex, becoming pale-white. Veil none. Gills adnate, 

 8 mm. (4 lin.) broad, distinct, cinereous-black, edge of the same 

 colour. 



In wet weather the pileus is spht and somewhat dehquescent ; when dry, 

 however, it is tirmer, tan obsoletely turning to flesh-colour. The spores are 

 dead black on white paper, fuscous-dead black on black paper. The habit is 

 almost that oi A. gracilis. The largest of this group, but very fragile. 



Among Stumps of a wooden pavement. Sibbertoft, 1870. Sept. 



Pileus at first sienna-brown, at length whitish, often transversely cracked.

778. A. pronus Fr. — Pileus 8-12 mm. (4-6 lin.) broad, fuligi- 

 nous when moist, hoa7y wlien dry, hygrophanous, membranaceous, 

 campanulate then hemispherical, very obtuse, smooth, pellucid- 

 striate, obsoletely slightly silky-atomate when dry. Stem 4 cent. 

 {1% in.) long, very ^sinXoso:, Jiliform, Jiexuous, lax, equal, very 

 smooth, pruinose at the apex under a lens, becoming pale. Gills 

 adnate, plane, somewhat triangular, distajit, 4 mm. (2 lin.) broad, 

 livid-fuliginous, with black dots from the spores. 



Spores very dead black. 



In grassy places. Rare. Aug.-Oct.
