MYCENA. 107 



rather tliick, somewhat distant, 1| line broad, white, be- 

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

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

 ending abruptly. 



Agaricus (^Mijcena) siidorus, Fries, Syst. Myc, i. p. 156; 

 Cke., Hdbk., p. 80 ; Cke., Illustr., pL 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. 

 Gills broad. (Fries.) 



Mycena galericulata. Scop. 



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

 at length expanded, umbonate, dry, glabrous, striate u]3 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 

 tapei'ing, rooting, hollow ; spores 6-7 X 4 /x. 



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

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



On trunks and stumps. 



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

 di tiers 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 ca^spitose. 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 (J[. alcalinus), sometimes nearly free, often pinkish. 

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

 base, which is densely stri^iose. Inodorous, insipid. (Berk.)
