86 ELEVENTH REPORT. 



Stockholm plants. I have not seen the typical Swedish plant in this country, 

 and Peck's specimens were evidently not typical, as he says no yellowish 

 stains occur in the stem. The stem soon l^ecomes soft and then develops 

 this characteristic translucent light yellowish color. 



Several varieties occur in Europe without the characteristic stem, and our 

 forms can perhaps be referred to them. R. sphagnophjld (which see), could 

 be considered as a var. of R. pueUaris. Peck refers to R. puellaris var. mtensior 

 Cke., a form with white stem, deep purple cap and mild taste, which has also 

 been found in Michigan. 



48. RUSSULA SPHAGNOPHILA SP. NOV. 



(The sphagnum-loving Russula.) 



PiLEus 2-4.5 cm. broad, very fragile, convex, umhonate, margin at length 

 elevated and disk depressed and purplish-red or rosy-red, the space between 

 the umbo and the margin pale olive-l)rown, covered by a viscous pellicle 

 glabrous, margin slightly striate. Flesh reddish under the cuticle and under 

 the surface of stem, fragile. Gills white then pale ochraceous, narrow, 

 ;adnate-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, 4-5 cm. long, 

 7-12 mm. thick. Spores cream-color globose, echinulate, 6-7 micr. Taste 

 mild. 



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

 and September. 



Whole plant very fragile, always with an und)0, subpellucid and rosy stem, 

 and pale gills. The only other Russula Avith an umbo, known to me, is R. 

 caerulea Pers., which differs in color and habitat. The red color rubs off on 

 paper when moist. In some points it is near R. roseipes, in others near R. 

 Mariae. It it nearest R. puellaris, and might perhaps ]:»e referred to it as 

 a variety, but without settling anything as to its origin. 



49. Russula roseipes (Sec.) Bres. 

 (The rosy-stemmed Russula.) 



Illustrations: Hard's Mushrooms, 1908. P. 191, fig. 151. 



PiLEUS 2.5-5 cm. broad, thi7i, fragile, convex then piano-depressed, with a 

 viscid, separable pellicle, margin tubercular-striate when mature, soon dry, 

 rosy-red or fiesh-red, disk tending to ochre-yellowish. Flesh white, thin, 

 unchanged. Gills soon truly ochraceous, subdistant, mostly equal, Ijroadest 

 in front, ventricose, narrowly adnate or almost free, few forked, interspaces 

 venose. Stem white and rosy-sprinkled, stuffed then cavernous, eciual or 

 tapering upward, even, 2.5-5 cm. long, 5-12 mm. thick. Spores ochraceous, 

 globose, echinulate, 8-10 micr. Taste mild. Odor none or pleasant. 



Solitary or scattered. In mixed woods, but usually under conifers. Only 

 found in the northern part of the state. July and August. 



A middle-sized to small plant, fragile, and Avith a rosy mealiness on the 

 stem. This last is quite characteristic of the species. It occurs under spruces 

 and balsams in moist places. It is quite distinct from R. puellaris Fr., to 

 which Fries, Avho had never seen Secretan's plant, referred it as a variety 

 R. purpurina also has a rosy-sprinkled stem, but is very viscid and more 

 brilliant shining red on the cap.
