Gli THE AGARICACEAE OF MICHIGAN 



reddish-brown, not striate, rimose in wet weather, at first densely 

 scaly, becoming fibrillose-scaly, margin at first involute and tomen- 

 tose. FLESH rather thin except disk, white at first, becoming 

 tinted with rufous hues. GILLS subadnate then sinuate, moder- 

 ately broad, broader than the thickness of the flesh, close, pallid 

 then rufescent in age or when bruised. STEM 5-7 cm. long, 10-15 

 mm. thick, subequal, somewhat irregular, hollow, nbrillose or lacer- 

 ated-fibrillose, fibrils reddish-brown, pallid elsewhere but rufescent. 

 SPOKES sphoeroid, 5x4 micr., smooth, white. TASTE somewhat 

 disagreeable, subastringent. ODOR similar. . 



Gregarious-subcaespitose. On the ground under conifers. .In 

 the northern portion of the State. August-September. 



The stuffed then hollow stem and the dense fibrillose scales of 

 the reddish-brown cap distinguish it. The color of the cap in large 

 specimens approaches umber, but the rufous shades are always pres- 

 ent. The margin of the pileus is distinctly tomentose.

 N. Y. State Mus. Rep. 41, 1888. 



"PILEUS 5-10 cm. broad, broadly convex or nearly plane, some- 

 times slightly depressed in the center, firm, dry, obscurely striate 

 on the margin, pale alutaceous, inclining to russet. FLESH white. 

 GILLS adnexed, thin, narrow, close, pale yellow, becoming brown 

 or purplish-brown in drying. STEM stout, 5-7 cm. long, 1-2 cm. 

 thick, short, firm, tapering upward from the thickened or subbulb- 

 ous base, white. SPORES broadly elliptical or subglobose, 7 micr. 

 long." 



Reported by Longyear from Chatham in the north, and from Lan- 

 sing. I have not found it. The peculiar hue of the dried gills is 

 said to characterize it.

PILEUS 4-0 cm. broad, campanulate at first, then subexpanded,
