COPRINARII. 345 



** Stemflexuous, pruinate at the apex. Psathyrelia. 



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

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

 then campanulate, at length flattened, smooth, the somewhat 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, attenuated from the thickened 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 split and somewhat deliquescent ; when dry, 

 however, it is firmer, 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 of 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. 

 Stem fibrillose. Gills ventricose, B. & Br. Name cauda, a tail. Fur- 

 nished with a tail-like root. Fr. Monogr. i. p. 449. Hym. Eur. p. 314. B. & 

 Br. n. 1261. Paul. t. 124. /. i, 2. 



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

 nous when moist, hoary when dry, hygrophanous, membranaceous, 

 campanulate then hemispherical, very obtuse, smooth, pellucid- 

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

 (\y 2 in.) long, very fistulose, filiform, Jlexuous, lax, equal, very 

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

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

 livid-fuliginous, with black dots from the spores. 



Spores very dead black. 



In grassy places. Rare. Aug.-Oct. 



Name promts, prostrate. P'rom the lax stem. Fr. Monogr. i. p. 450.

779. A. empyreumaticus B. & Br. Pileus 4 cent. (i> in.) 

 broad, rufous then becoming pale, hygrophanous, expanded, 

 atomate ; margin crenate. Stem 6 cent. (2}4 in.) long, 3 mm. 

 (i)4 lin.) thick, narrowly but distinctly fistulose, silky- furfur- 

 aceous, pallid. Gills adnate, with a decurrent tooth, broad, 4 

 mm. (2 lin.) thick, distant, connected by veins, rufous then brown- 

 purple, pallid at the edge. 



Resembling A. confragosus so closely that, till the spores were observed, it 

 was taken for that species.
