CLASSIFICATION OP AGARICS 



t eristic, translucent, light yellowish color. Several varieties occur 

 in Michigan differing mainly from the above description In the red 

 caps and oon-lutescenl stems; these are referred here for the prea 

 ent. 



148. Russula sphagnophila Kauff. 



Mich. Acad. Sci Rep. 11, p. 86, 1909. 



I'lLKl'S l' i.r> cm. broad, very fragile, convex, umbonate, margin 

 at length elevated and disk depressed and purplish red or rosy red, 

 the space between the umbo and the margin pale olive-brown, cov- 

 ered by a viscous pellicle glabrous, margin slightly Btriate FLESH 

 reddish under the cuticle and undes the Burface of the stem Fragile. 

 GILLS while then pale ochraceous, narrow, adnato-decurrent, 

 rather close, narrowed toward both ends, few forked here and there. 

 STEM rosy-colored, usually ventricose or irregularly swollen. 

 spongy-stuffed then cavernous, very fragile, rivulose-uneven, 1 -."> cm. 

 long, T-lL* nun. thick. SPORES cream-color, globose, echinulate, 6-7 

 micr. TASTE mild. 



Scattered. On sphagnum, in swamps. Cold Spring Harbor. 

 August and September. Rare. 



Whole plant very fragile, always with an umbo, subpellucid and 



rosy stem, and pale gills. The only other Russula with an umbo, 



known to me, is /,'. caerulea Pers. which differs in color and hab 

 itat. The red color rubs off on paper when moist. In some points 

 ii is near /'. rose&pes, in others it is nearest /,'. puellaris, and might 

 perhaps be referred to the latter as a variety hut without settling 

 anything as to its origin. 



149. Russula chamseleontina FY. (Edibi 



Epicrisis, 1836-38.

PILEUS 2-5 cm. broad, rather small, fragile, thin, piano depressed, 

 with a viscid separable pellicle, margin even at ftrsl then Btriatulate, 

 color varying for different pilei, mostly some -hade of red, purple, 

 etc. fading to yellowish especially on disk. FLESB white, thin. 

 GILLS thin, crowded or close, adnexed or almost free, eqnal, rather 

 broad, Bometimes almosl narrow, tew forked, interspaces >
