PLUTEUS. 287 



Agaricus salicinus, Pers., Syn., p. 344 ; Cke., Hdbk., p. 371 ; 

 Cke., Illustr., pi. 1169A. 



On willow trunks. 



Distinguished from P. ephebius by the pileus not being 

 downy, rather umbonate, and floccosely rugose at the disc. 

 Fries gives two varieties : 



Var. beryllus, Pers., Syn., p. 334 ; pileus with greenish 

 streaks. On alder. 



Var. floccosa, Karst. ; pileus floccosely squamulose. 



Most nearly allied to Pluteus ephebius, but two or three 

 times smaller. Stem stuffed, 1-2 in. long, 1 line or a little 

 more thick, equal, fibrillose, fragile, white with a bluish 

 tinge, or sometimes greenish ; pileus rather fleshy, convex 

 then plane, somewhat umbonate, 1 in. and more broad, 

 glabrous, but the disc floccosely rugulose, and darker, grey ; 

 gills exactly as in P. ephebius, but smaller. Approaching 

 the genus Leptonia in the dark, rugulose disc. (Fries.) 



Pluteus pellitus. Fr. (figs. 4, 5, p. 236.) 



Pileus 1-2 in. across, flesh thin, soft, white, convex then 

 plane, somewhat umbonate, regular, silky- fibrous, dry, white ; 

 gills free, rounded behind, crowded, 1^- line broad, ventricose, 

 white then flesh-colour, margin slightly toothed ; stem about 

 2 in. long, 2-3 lines thick, slightly thickened at the base, 

 even, glabrous, shining, white, stuffed ; spores elliptical, 

 smooth, 10 X 6 p.. 



Pluteus pellitus, Fries, Epicr., p. 141; Cke., Illustr., 

 pi. 597. 



Among grass at the roots of trees, &c. 



Our only Pluteus with a pure white, even pileus and stem. 

 Superficially resembling Entoloma prunuloides, which differs 

 in the broadly emarginate not free gills, and in the strong 

 smell of new meal. 



* Pileus rather mealy or atomate, 



Pluteus nanus. Pers. 



Pileus 1-1^ in. across, flesh thin, convex then plane, ob- 

 tuse, umber or smoky brown, rugulose, minutely flocculose or 

 pruinose ; gills free, but rather close to the stem, li-2 lines
