lyo AGARICUS. 



Pleurotus. smooth ; flesh thin, tough, watery-pallid. Stem very short, about 

 12 mm. {}4 in.) long, 4-10 mm. (2-5 lin.) thick, stuffed then hol- 

 low, somewhat equal, round or compressed, tough, even, pubes- 

 cent at the base. Gills wholly adiiate, horizontal, at length 

 ascending and divergent in the lobes of the reflexed pileus, very 

 narrow, very thi?i, very crowded, white. 



Very polymorphous, gregarious, somewhat casspitose. A remarkable species ; 

 from its most manifest affinity with A. lignatilis, it may readily be believed 

 that tht* pileus is at first pruinose. Odour of new meal, obsolete. 



On dead trunks. Rare. Aug.-Jan. 



Pileus about 7.5 cent. (3 in.) broad. In the figure of Bolton the pileus is 

 more crisped -fimbriate than in the specimens of Fries. Esculent, but so rare 

 that it is valueless. '^2imQ—Jimbri(B, fringe. With/ringed margin. Bo/^. t.

367. A. Ruthse B. & Br.— Pileus 4 cent. (i>^ in.) broad, whit- 

 ish, fan-shaped, slightly hispid above the gelatinous stratum, the 

 very thin margin striate. Stem short, lateral, hispid. Gills 

 white, rather broad, acute behind, anastomosing, with a reddish 

 tinge like that of the stem, interstices veined. 



The pileus is of a dirty white, with a hyaline aspect. Mycelium fibrous.

368. A. lignatilis Fr. Dingy whitish.— Pileus 2.5 to 7.5- 

 10 cent, (i to 3-4 in.) broad, rarely central, commonly more 

 or less excentric, occasionally wholly lateral, often reniform, 

 fleshy, thin, but compact and tough, fissile, convex then plane, 

 obtuse and often \imh\\\c3i\.t,_/locciiloso-prtnnate, at length denud- 

 ed with rain, repand, margin at first involute then expanded, un- 

 dulato-lobed when luxuriant. Stem sometimes 5-7.5 cent. (2-3 

 in.) sometimes 6-8 mm. (3-4 lin.) long (even obliterated), stuffed 

 then hollow, always thi7i, unequal, curved or flexuous, tough and 

 flexile, whitish, everywhere pruinato-villous, rooting and some- 

 what tomentose at the base. Gills adnate, very crowded and 

 narrow, unequal, divergent in the lobes, shining white. 



Exceedingly variable, wholly inconstant in form ; substance thin and pliant ; 

 commonly densely caespitose, but also single. Odour strong of new meal. 

 Of its many forms one is conspicuous : var. tephrocephalus, pileus more compact, 

 disc black, then cinereous, margin white.
