PHOLIOTA ADIPOSA. 

 About natural size. 



Pileus fleshy, firm, at first hem- 

 ispherical or subconical, then convex, 

 very viscid or glutinous when moist, 

 scaly, yellow. Flesh whitish. Gills 

 close, adnate, yellowish becoming 

 rust-color with age. Stem equal or 

 slightly thickened at the base, scaly 

 below the slight radiating floccose 

 ring, solid or stuffed, yellow, gener- 

 ally rust-color at the base. Spores 

 elliptical, 7.6x5^. 



The Fat pholiota is a showy spe- 

 cies. Its tufted mode of growth, 

 rather large size, yellow color and 

 rusty-brown scales make it a notice- 

 able object. The stem is somewhat 

 and the cap very viscid when moist, 

 and this viscidity when dry gives it a shining appearance. The scales 

 of the cap become erect or reflexed and sometimes appear blackish at 

 the tips. They sometimes disappear with age. The flesh is firm a-nd 

 white or whitish. The gills when young are yellow or pale-yellow, but 

 when mature they assume a ferruginous or rusty color like that of the 

 spores. The stem is similar in color to the cap, but paler or nearly 

 white at the top and usually reddish-brown or rusty-brown at the base. 

 The collar is slight and often scarcely noticeable in mature specimens. 



The Cap is 2-4 in. broad, the Stem 2-4 in. long and 4-6 lines thick. 

 The plants commonly grow in tufts on stumps or dead trunks of de- 

 ciduous trees in or near woods. They may be found from September 

 to November. It is well to peel the caps before cooking. This species 

 is not classed as edible by European authors, but I find its flavor agree- 

 able and its substance digestible and harmless. Peck, 49th Rep. N. Y.
