CLASSIFICATION OF AGARICS 155 



Section II. Taste acrid. Spore-mass cream-color, yellowish, 

 ochraceous to alutaceous. 



134. Russula sanguinea Fr. {R. rosacea Fr.) 



Epicrisis, 1836-38. 



Illustrations: Cooke, 111., PI. 1020 (as B. rosea). 



Michael, Filhrer f. Pilzfreunde, Vol. 11 (as R. rosacea). 



PILEUS 3-G cm. broad, rather firm at firsf, suhfragile, convex- 

 plane or depressed, rosy-red, vHscid, margin acute and thin, pellicle 

 subadnate, easily separable on margin and tubercular-striate. 

 FLESH rather thin, white, red under the pellicle. GILLS slightly 

 adnate, close to subdistant, equal, not broad, creamy-icUite. STEM 

 4-6 cm. long, subequal or tapering down, often eccentric, tvhite or 

 tinged rosy-red, spongy-stuffed then cavernous, rather fragile, glab- 

 rous, even. SPORES creamy-white in mass. TASTE tardily but 

 truly acrid. 



Gregarious. On the ground among grass in frondose woods. Ann 

 Arbor. September-October. Infrequent. 



The plants referred here are R. rosacea in the sense of Romell, and 

 R. sanguinea according to most of the modern French mycologists. 

 They are distinguished by the cream color of the spores and gills. 

 The gills are not decurrent as they are supposed to be in R. rosacea, 

 but the stem is often eccentric as that species is described by Fries. 

 Bresadola, Maire, etc., conceive R. rosacea Fr. as a plant with pure 

 white gills and spores. Our plant agrees with a species, common 

 around Stockholm, whose gills are usually creamy-white. It was 

 placed by Fries among the rigid forms but is almost too fragile. 

 It is not large and except for the color of the spores small forms 

 might be mistaken for R. fragilis. 



135. Russula veternosa Fr. 



Epicrisis, 1836-38. 



Illustrations : Bresadola, Fungh. mang. e. vel., PI. 75. 

 Cooke, 111., PI. 1033. 



PILEUS 5-7.5 cm. broad, convex then expanded, with a somewhat 

 separable pellicle, indistinctly striate on the margin, deep rose-red 

 (like R. emetica), viscid when moist. FLESH white, red under the 

 cuticle. GILLS white at first, then straw-color or pale ochraceous,
