rather dark olive-green, disc often darker, and frequently 

 with a tinge of purple, covered everywhere at first with a 

 dense, whitish bloom, margin very slightly striate ; cuticle 

 separable ; flesh about 2 lines thick, becoming thinner at 

 the extreme margin, firm, white ; gills very narrow behind, 

 and very slightly adnexed, broader in front, 2 lines broad, 

 crowded, brittle, often forked behind, with a few shorter 

 ones that reach nearly to the base, connected by veins, pale 

 cream colour from the first, not becoming darker; basidia 

 clavate, sterigmata elongate, spores subglobose, minutely 

 warted, colourless, about 9 X 8 /* diameter; cystidia absent; 

 stem 1^ in. long, | in. thick, nearly equal or slightly swollen 

 at the "base, very "slightly longitudinally rugulose, solid but

 Hdbk., p. 328; Cke., Illustr., pi. 1088. 



Among grass under trees. 



Allied to R. cyanoxantha, but smaller, and at once dis- 

 tinguished by the dense mtaly layer, resembling bloom, on 

 the pileup, the smooth spores, and absence of cystidia. 



Russula virescens. Fr. 



Mild. Pileus 3-5 in. across, flesh rather thick, white; 

 globose then expanded, and at length depressed, often un- 

 equal, always dry, not furnished with a distinct pellicle, the 

 flocculose cuticle becoming broken up into areolate warts ; 

 margin straight, obtuse, even, dingy opaque green, gills free, 

 somewhat crowded, narrowest in front, equal or sometimes 

 forked, a few short ones intermixed, white ; stem solid, 

 spongy within, firm, white; spores 8 X 10 ,u. 



Hussula virescens Fries, Epicr., p. 355 ; Cke., Hdbk., p. 324; 

 Cke., Illustr., pi. 1039. 



In woods. 



Readily distinguished from every species by the green 

 pileus without a pellicle, at first innately flocculose then 

 rivulose, and broken up into areolate squamules. (Fries.) 



Russula furcata. Fr. 



Mild at first but soon bitter. Pileus 3-4 in. across, fleshy, 

 compact, gibbous then piano-depressed, or infundibulifonn, 

 even, glabrous, but often frosted with a slight silkiness,
