Il8 AGARICINI. 



Russula. fuscous, &c, fleshy, firm, convex then plane, more rarely de- 

 pressed, but commonly irregularly shaped and undulated, even, 

 the thin adnate pellicle presently changing colour especially at 

 the disc, the spreading margin even, but slightly striate when 

 old; flesh white. Stem about 4 cent. {1% in.) long, solid, firm, 

 commonly attenuated downwards, white, becoming cinereous when 

 old. Gills adnexed, broad, crowded, distinct, but commonly 

 forked at the base, often with shorter ones intermixed. 



Inodorous, taste mild. The colour of the pileus is at first pallid reddish or 

 inclining to fuscous, then whitish or yellowish, opaque in every stage of 

 growth. It approaches nearest to the Heterophyllcz. 



In beech woods, pastures, &c. Uncommon. Aug.-Sept.

 purple, compact, firm, convex then depressed, scarcely viscid

 firm, cylindrical, equal, tinged with purple. Gills adnexed, 

 scarcely crowded, narrow and furcate at the base, at first pale 

 sulphur-yellow, then deeper yellow, never white. 



Acrid, peppery. Spores pale ochre. The colour and habit similar to 

 R. Queletii, but distinguished by the yellow gills, ochraceous spores, and 

 intensely peppery taste.

12. R. lactea Fr.— Pileus 5 cent. (2 in.) broad, at the first milk- 

 white, then ta?i-white, throughout compactly fleshy, campanulate 

 then convex, often excentric, without a pellicle, always dry, at the 

 first even, then slightly cracked when dry, margin straight, thin, 

 obtuse, even ; flesh compact, white. Stem 4-5 cent. (1,^-2 in.)

 spongy-soft within, equal, even, always white. Gills free, very 

 broad, thick, distant, rigid, forked, white.

 must be taken not to confound it with other Russula: which have changed 

 colour and become white.
