Eijdnnm. imhricatum, Linn., Succ, n. 1257; Stev. Fung., p. 

 234. 



In pine woods. Flesh dirty white. There are two forms, 

 one with a plane pileus covered with thick, persistent scales, 

 the other with the pileus subinfundibuliform with thinner 

 scales that eventually disajipear. (Fries.) 



Pileus 2-5 inches broad, thick and fleshj'-, plane or slightly 

 convex, and rounded at the margin, at length somewhat 

 hollowed in the centre, pretty regular in form, varying in 

 colour from reddish to a kind of mouse-brown, scaly ; scales 

 imbricated, numerous, the central ones being often mere 

 cracked portions of the pileus, which renders that part 

 tessellated. Flesh pale, buffish, or reddish. Hymenium com- 

 posed of numerous, very short, obtuse, greyish-white, entire 

 spines of nearly equal length. Stipes central, 1-2 inches 

 long, often above 1 inch thick, firm, irregular, whitish. No 

 plant can be better characterised than tlie present one by its 

 scaly pileus and short thick stem. (Grev.)
