 fistiilose, tough, equal, somewhat smooth, but varying slightly 

 silky, beroining light yellow, white-villous at the base. Gills 

 adnate, 6-8 mm. (3-4 lin.) broad, plane, somewhat distant, pallid 

 then blackish, pruinose (becoming olive when the pruina disap- 

 pears) edge whitish.

727. A. udus Pers.— Pileus 1-2.5 cent. (>^-i in.) broad, brick- 

 tawny, becoming pale, slightly fleshy, convex then flattened, more 

 or less evidently umbonate, smooth, even or when old slightly 

 wrinkled. Stem 5-7.5 cent. (2-3 in.) long, 2 mm. (i lin.) or a

 plane or convex, pallid then bccoiniiig fuscous-purple. 



Not hygrophanous. Scattered, tough when young, slender. Very decep-

 is a var. with the pileus somewhat membranaceous, acutely conical, tawny, 

 and the gills pallid because sterile.
