MYCENA. 107 



rather thick, somewhat distant, 1^ line broad, white, he- 

 coming tinged flesh-colour; stem 3-5 in. long, 1-1^ line 

 thick, equal, firm, even, dry, almost glabrous, rooting but 

 ending abruptly. 



Agaricus (MycerM) sudorits, Fries, Syst. Myc, i. p. 156; 

 Cke., Hdbt., p. 80 ; Cke., Illustr., pi. 206. 



On beech trunks. 



Distinguished by the entirely white colour and viscid 

 pileus. 



Usually solitary, large, entirely white. Stem very long, 

 root long, ending abruptly, glabrous (perhaps not always ?) 

 Pileus 1 in. broad, diaphanous, often irregular, not rugose. 

 Crills broad. (Fries.) 



Mycena galericulata. Scop. 



Pileus |— 2 in. across, ilesh thin, conical, then campanulate, 

 at length expanded, umbonate, dry, glabrous, striate up to 

 the umbo, livid-brownish, greyish, pallid, &c. ; gills adnate 

 with a decurrent tooth, about 1 line broad, connected by 

 veins, whitish then tinged with pink; stem 2-4 in. long, 

 1-1^ line thick, equal, rigid, even, polished, pallid, base 

 tapeiing, rooting, hollow ; spores 6-7 X 4: /j,. 



Agaricus galericulatus, Scopoli, Cam., 445; Cke., Hdbk., 

 p. 80 ; Cke., Illustr., pi. 222. 



On trunks and stumps. 



M. rugosa is most nearly allied to the present species, but 

 differs in growing singly, shorter stem, grey gills, and 

 tougher substance. A form of M. galericulata sometimes 

 grows on the ground among leaves. 



Common on trunks, exceedingly variable, tufts often 

 densely crowded. Not tough and flexible, like M. rugosa. 

 Stems somewhat ascending, base downy, rooting, white, 

 tawny, bay, &c. (Fries.) 



Solitary or densely capspitose. Pileus 3-9 lines broad, 

 sometimes, however, much larger, campanulate or conical, 

 often subumbonate, at length depressed, innato-fibrillose, 

 striate, brownish-white, with sometimes tints of blue or 

 yellow. Gills rather distant, not so broadly adnate as the 

 last (^A. alcalinus), sometimes nearly free, often pinkish. 

 Stem very various in length, rigid, smooth, except at the 

 base, which is densely strigose. Inodorous, insipid. (Berk.)
