CLASSIFICATION OP AGARICS 



316. Cortinarius iodes B. & C. 



PILEUS 2-6 cm. broad, campanulate-convex, glabrous, even, with 

 a tough, viscid, separable pellicle, dark violet to purplish, at length 

 often yellowish on the disk. FLESH thick on the disk, abruptly 

 thin on the margin, violaceous then paler. QILLS adnate, close, 

 moderately broad, violaceous <it first, then gray-cinnamon. STEM 

 5 7 cm. long, equal or clavate thickened or tapering to either end, I v 

 or 5-15 nun. i hick, viscid, solid, subfibrillose. CORTINA pale vio- 

 laceous. SPORES broadly-elliptical, minutely rough-punctate, 8-10 

 x6-6.5micr. TASTE mild. ODOR none. 



Gregarious or subcaespitose. On the ground in low, wel places 

 in woods. August. Detroit. Infrequent. 



This is very similar in color and stature to C. i<><l< <>uh ■■* hut hicks 

 the bitter taste of the pellicle of the cap. The color is deeper and 

 the spores arc larger than in that species, li appears t<> be related 

 to the European C. salor Fr. which has similar colors bu1 whose 

 spores are truly spherical. It has been received from the eastern 

 pari of the United States where it occurs more frequently.

PILE1 S 2 ."> cm. broad, convex then expanded, broadly umbonate 

 t" plane, deep lavender-violet or bluish violet when young or fresh, 

 fading t<> livid-ashy, sometimes faintly yellowish or buff-spotted, 

 with ii bitter pellicle ninth is glutinous when moisl or young, gla- 

 brous, even. PLESB at tirsi pale violaceous, soon white, thin on

 universal veil, stuffed, silky or glabrous. SPORES elliptical, al- 

 most smooth. 7 -"."» x ll..") micr.. pale ferruginous-cinnamon in mass. 

 ODOR none or slight. TASTE of flesh mild, of pellicle of pileus 

 bitter. 



Subcaespitose or gregarious. Among leaf-mold, often hidden by 

 leaves, in frondose woods of maple, oak, etc. August-October. Ann 

 Arbor, New Richmond. .Mote frequenl than the preceding. 



This species is easily coni'iiseil with the preceding, bu1 Is clearly 

 distinct because of the bitter surface of the cap which i> quickly
