CLASSIFICATION OF AGARICS 699 



Section II. Rigida. Pellicle of the pileus rigid, with a tendency 

 to crack into small smooth scales, sometimes punctate-granulose; 

 neither viscid, floccose-scaly nor fibrillose. Flesh of pileus rigid, 

 s ewhal cartilaginous. 



*Gilts not becoming reddish nor cinereous, nor yellow-stained.

PILEUS 4-8 cm. broad, convex-expanded, firm, glabrous or be- 

 coming cracked to form small scales, not virgate, pale livid-brown 

 to lead-gray but variable in color, often olive tinged, margin at first 

 naked and incurved. FLESH white, becoming pinkish, thick, firm. 

 GILLS adnato-emarginate then uncinate, subdistant, distinct, 

 rather broad, whitish, not cinerascent, edge entire. STEM 5-8 cm. 

 long, L.5-2 cm. thick, rather stout, ventricose, attenuated or sub- 

 radicating below, solid, tilu'oiisflcshv. apex flocculose, becoming 

 pink within, white without, glabrous varying to floe-cose or minute- 

 ly dark-scaly. SPORES minute, elliptical-ovate, smooth, 5x3-3.5 

 micr. ODOPi and TASTE strongly oily-farinaceous (soapy), dis- 

 tasteful. 



Solitary or gregarious. In frondose woods, on the ground. Sep- 

 tember-October. Ann Arbor, New Richmond, Detroit. Infrequent. 



The colors of tin- pileus vary and are difficult to describe, some- 

 times varying from whitish to grayish-brown or smoky-brown. The 

 gills are said to become greenish <>r rufescent at times. The odor, 

 color of the flesh and minute spores distinguish it. Where bruised 

 the flesh of the stem retains the pink tinge in a persistenl manner, 

 and this character is quite marked. It is unlit for fund mi account 

 of its taste. The odor and taste are sometimes very slight. 7'. /»>/- 

 lidum Pk. is probably a variation of this species.
