CLASSIFICATION OF AOAR1CS 



its margin is benl down rorming a fainl zone, and fulvoua shades 

 radiate in streaks from ilit- fnlvona center. The bulb is narrow, 

 somewhat thicker than the stem, and scarcely depreaaed. Its 

 caeapitoae habit is very marked. No good plate seems to exist. 

 Gooke'a figure (111., PI. 712) is entirely misleading, ami <iillet's 

 figure (Champignons de Prance, No. 224), doubtless illustrates an- 

 other species. H is qoI at all commmon in the regions 1 have visited. 



**(Hils, fit sh or stem <ii first green. 



337. Cortinarius virentophyllus sp. nov. 



PILEUS 5-8 em. broad, convex, expanded-plane, regular, viscid, 

 glabrous, green to olwaceous-yellotcish, fading to pale ochraceous <»!■ 

 Btraw-yellow, sometimes tinged fulvoua, slightly streaked by the 

 drying gluten. FLESH thickish on disk, M-\y thin on margin, 

 pallid-greenish, fading, subhygrophanous, with dark watery-green 

 border along the gills. (JILLS adnexed-emarginate, thin, (lose, 

 somewhat narrow, gray-olive or green at first, becomiu;/ <Ic</> green, 

 edge entile. STEM 5-7 em. long, LO-15 mm. thick, silky-fibrilloae at 

 Length, Stuffed by a fibrous pith, becoming hollow, distinctl;/ 

 cyaneous or pah- blue, fading to violaceous-whitish, bluish within 

 but fading, equal along tin- subemarginate bulb, which becomes oval 

 or subobsolete. SPORES almond shaped, broadly elliptical, dis- 

 tinctly tubmen lute, '.ill x i; 7 micr. BASIDLA 36x9 micr., L-spored. 

 odor mild. TASTE of flesh and pellicle of cap mild. 



Subcaespitose in clusters of few individuals. <>n the ground, 

 among .^r;iss in fr'ondose woods of oak, maple, etc Ann Arbor. 



October-November. Rare. 

 This attractive species was found only twice. The cap ami gills 



;iie deep green when fresh, while the stem is pule blue. The color 



of the cap ami flesh soon lades to pale yellowish except near the 



gills. The ;i\is of the stem is composed of softer, pnler. fibrOUfi 

 tissue which fades quickly and disappears in part Leaving the stem 

 tubular. The bulb is not truly depressed limrejnate unless in the 

 button stage which was not seen. The species is related to ('. 

 8CaurUS, but the pilens is differently colored, not "tiger-apotted," 

 and the stem not solid. The gilla and stem are ;ilso more brightly 

 colored than in that species. It may be an American variety. Tin 



spores agree closely with the measurements given by Ricken for 

 0. scaur us. h differs from C prasinus in the glabrous pileua, in 

 stature, and in the spores, which according to Ricken are L3 L6 \ 6-7 



micr. in size. Specimens were seen from Madison. Wisconsin.
