770 THE AGARICACEAE OF MICHIGAN 



lower portion indicated that it was clearly a monstrous form of 

 this species; it was growing on the mine timbers. Whether it is 

 truly parasitic. on living trees has not been satisfactorily proven. 

 When preparing it for table use, it is best to peel off the viscous 

 pellicle of the cap.

"PILEUS 3-5 cm. broad, convex-expanded, subumbonate, dry, 

 radiate-wrinkled, clear brown, disk darker, densely velvety with 

 short brown hairs. FLESH thin. GILLS almost free, rather broad, 

 subdistant, ventricose, pure white, edge fimbriate. STEM 8-12 cm. 

 long, 4-5 mm. thick, solid, firm, straight, thicker below, the base 

 prolongated into an oblique "root," white within, leather-brown to 

 chestnut-brown, pale above, covered with spreading, tomentose, 

 brown hairs. SPORES broadly elliptical, 9-10 x 6-7 micr., smooth, 

 white. CYSTIDIA large, flask-shaped, 55x17 micr., scattered on 

 sides and edge of gills." 



On decayed wood, stumps and logs. 



Not with certainty found within the State. The description is 

 adopted from Schroeter, as my notes are incomplete. The plant has 

 much the appearance of C. radicata, but the pileus is dry and velvety. 

 Mcllvaine reports it in West Virginia, but his remark that "it is 

 more glutinous'' than G. radicata eliminates his claim. It is in- 

 cluded for purposes of comparison.

PILEUS 1-3 cm. broad, subcartilaginous, campanulate to convex, 

 cinereous-brown to fuliginous, minutely pubescent, margin incurved 

 and surpassing the gills. FLESH thickish, white at first, becoming

 current tooth, becoming emarginate, moderately broad, tapering in 

 front, close, whitish, turning blackish where bruised.- Stein 2-5
