KUSSULA. 47 



Russula olivacea. Fr. 



Mild. Pileus 3-4 in. across, flesh white, becoming yellowish, 

 thickish at the disc, margin thin ; convex then expanded and 

 depressed, minutely squamulosely silky, margin straight, 

 even, dingy purple with an olive tinge, or entirely brownish- 

 olive ; gills adnexed, broad, forked and mixed with shorter 

 ones, yellow; stem 2-3 in. long, f in thick, ventricose, pale 

 rose-colour, spongily-stuffed ; spores globose, minutely granu- 

 lar, yellow, 9-10 ^ diameter.

 Cke., Illustr., pi. 1041. 



In pine woods, &c. 



A well-marked species, distinguished by the dark-coloured, 

 minutely broken up surface of the pileus, rose-coloured stem, 

 and yellow gills. Differs from It. rubra in the deeper yellow 

 gills and the unpolished pileus. JR. alutacea differs in the 

 striate and tuberculose margin of the pileus : the same 

 features along with the powdered gills separate E. integrct 

 from the present species. 



Russula Linnaei. Fr. 



Mild. Pileus 3-4 in. across, flesh everywhere thick, com- 

 pactly spongy, white, rigid ; plane then depressed, sometimes 

 wavy, even, glabrous, polished, dry, without a separate 

 pellicle, all one colour, deep blood-red or dark rose ; margin 

 spreading, obtuse, not striate ; gills slightly decurrent, 

 rather thick, not crowded, broad, fragile, sparingly connected 

 by veins, somewhat anastomosing behind, and with shorter 

 ones intermixed, white, yellow when dry ; spores white, sub- 

 globose, minutely echinulate, 9-11 X 8-9 p; stem l-2$ in. 

 long, 1 in. and more thick, slightly ventricose, indistinctly 

 fibrillosely reticulated, deep blood-red, firm but soft and 

 spongy within, and sometimes becoming hollow.

 1026 ; Cke., Hdbk., p. 326. 



In woods. 



Distinguished among mild species by the even blood-red 

 pileus and stem. 



Habit exactly that of JR. emetica. Substance truly floccose 

 bat very compact, firm, thick. Stem deep blood-red (but 

 perhaps varies to white), indistinctly fibrillosely reticulate.
