 Cke., Illustr., pi. 49. 



In woods. 



The gills in " Illustrations " should have been cinereous,

Fries says that the scent is strong and nitrous ; he

 Berkeley says the smell is slight and not at all nitrous,

 neither powerful nor nitrous. Stem 3 in. high, 1 in. thick at 

 the top, cracked and streaked, silky, with minute black 

 scales, solid but fibrous, not the least stufied or hollow.
