more uniform and darker color of the pileus and darker color of the 
mature lamellae and spores are its peculiar features. It is often very 
caespitose and is found especially among alder bushes in swamps.

Pileus fleshy, thin, convex or nearly plane, even, glabrous, viscid, 
subtawny, flesh yellow; lamellae broad, adnate, crowded, brownish- 
clay color; stem equal or tapering downward, slender, rigid, nar¬ 
rowly fistulose, fibrillose-squamulose, pallid; spores brownish-fer¬ 
ruginous, .0003 to .0004 in. long, .00016 to .0002 broad.

European authors do not agree as to the dimensions of the spores 
of this species. In Sylloge they are given as 10 to 11 x 5 to 6. In 
British Fungus Flora, as 7 x 3.5. Fries describes the pileus as one 
inch or a little more in width, but Cooke represents it as much 
broader, sometimes reaching three inches in diameter. The on!}/ 
specimens we have ever seen that agree tolerably well with the 
description of the European plant were found growing on ground 
where wood had been burned into charcoal a short time before.
