120 AGARICINI. 



Russula. Taste mild ; wholly compact and firm, but the flesh is cheesy not somewhat 



grumous. The gills are often red at the edge chiefly towards the margin, on 

 account of the margin of the pileus being continuous with the gills. 



In mixed woods. Frequent. Sept.-Oct.

16. R. rubra Fr. Pileus unicolorous, cinnabar-vermilion, but 

 becoming pale (tan) when old, disc commonly darker, compact, hard 

 but fragile, convex then flattened, here and there depressed, abso- 

 lutely dry, without a pellicle, but becoming polished-even, often 

 rivuloso-rimose when old, margin spreading, obtuse, even, always 

 persistent; flesh white, reddish under the cuticle. Stem 5-7.5 

 cent. (2-3 in.) long, about 2.5 cent, (i in.) thick, solid, even, vary- 

 ing white and red. Gills obtusely adnate, somewhat crowded, 

 whitish, then yellowish, with dimidiate and forked ones inter- 

 mixed. 



Very acrid, very hard and rigid, most distinct from all the others of this 

 group in the pileus becoming polished-even, although without a pellicle, in the 

 flesh being somewhat grumous, and in the very acrid taste. Gills often red at 

 the edge. 



In mixed woods. Frequent. Aug.-Nov.

 times repand, even, smooth, dry, without a separable pellicle,

 (i in.) and more thick, stout, firm, but spongy-soft within, some- 

 what ventricose, obsoletely jibrilloso-reticulate, intensely blood- 

 red. Gills adnate, somewhat decurrent, rather thick, not crowded, 

 broad (mme. than 12 mm., y z in.), fragile, sparingly connected by 

 veins, white, becoming yellow when dry, with a few dimidiate 

 ones intermixed, somewhat anastomosing behind.

 floccose, but very compact, firm, and thick. The stem according to v. Post 

 is hollow.
