MYCENA. 87 



IV. LACTIPEDES. 



Mycena leucogala. Cooke. 



Pileus l^-f in. high and broad, flesh thin, dingy; campanu- 

 late, umbunate, snlcate to the middle, purple-brown, margin 

 paler, umbo blackish ; gills adnate Avith a slight decurrent 

 tooth, rather distant, grey, about 1 line broad ; stem 2-3 in. 

 long, about 1 line thick at the base, slightly thinner upwards, 

 hollow, coloured like the j^ileus, with whiti.sh d(jwn at the 

 base, containing a large quantity of white milk that escapes 

 in drops when the stem is broken. 



Agaricus (3Iycena) leiicogcdus, Cke., Grev., xi. p. 41 ; Cke., 

 Hdbk., p. 88 ; Cke., Illustr., pi. 653. 



On rotten stumj^s, &c. 



Pileus ^ in. high and broad, not exceeding 1 in. Stem 

 3 in. long ; forming dense caespitose tufts. Very similar 

 in general appearance to M. piiUata, Berk. & Cke. (Cooke.) 



Closely allied to dark forms of M. galopoda, but the latter 

 differs in the pileus not being so coarsely striate, and in the 

 nearly white gills. 31. puUata differs in the absence of milk 

 in the stem, and in the slight alkaline smell. 



M. atrocy emeus also resembles the present species, but differs 

 in the absence of milk in the stem. 



Mycena galopoda. Fr. 



Pileus 3-7 lines broad, membranaceous, conical then cam- 

 panulate, more or less umbonate, striate, naked or prninose, 

 at first blackish then gre}^ but sometimes white with a 

 blackish or brownish umbo; gills narrowed behind and 

 adnexed, broad towards the margin, white or with a faint 

 greenish tinge ; stem 2-3 in. long, 1 line thick, rather fragile, 

 even, glabrous or j)i'^^iiiose, greyish-black, apex paler, base 

 rather thickened, downy and rooting, giving out a large 

 quantity of white milk when wounded ; spores elliptical, 

 9-10 X 5 /X.

 pL 207b; Cke., Hdbk., p. 87. 



Among moss, on trunks, &c. 



M. leucogala resembles the darker forms of the present 

 species, but differs in the gills being grey and connected by 

 veins.
