RUSSULA. 127 



more, flesh-colour, changing colour, very thin, fleshy only at the Russula. 

 disc, at the first convex and often umbonate, then plane and 

 depressed, pellicle thin, becoming pale, slightly viscid in wet 

 weather; margin very thin, tuberculoso-striate. Stem 4-5 cent. 

 (1^-2 in.) long, spongy within, soon hollow, often slightly 

 striate, white. Gills slightly adnexed, very thin, crowded, broad, 

 ventricose, all equal, shining white. 



Very acrid. Smaller and more fragile than the rest of the group, directly 

 changing colour. The colour is variable, often opaque, typically flesh-colour, 

 when changed in colour white externally and internally, often with reddish 

 spots. Among varieties of colour is to be noted a livid-flesh-coloured form, 

 with the disc becoming fuscous. 



It is not easy to define it from fragile forms of R, emetica, but the gills are 

 much more crowded, thinner, and often slightly eroded at the edge, ventricose ; 

 the pileus thinner and more lax, &c.
