long. Spores ellipsoid, ochraceous-tawny, 7 x 4 p. The 

 scales of the pileus are brown-tipped when the plants are mature. 



Pholiota adiposa Fr. 



Pileus fleshy, firm, at first hemispherical or subconical, then 

 convex, viscid when moist, shining when dry, squamose, yellow; 

 flesh whitish. 



Lamellae close, adnate, yellowish, becoming ferruginous with 

 age. 



Stem equal or slightly thickened at the base, squamose below 

 the slight radiating annulus, solid or stuffed, yellow, generally 

 ferruginous at the base. 



Pileus 5 to 10 cm. broad; stem 5 to 10 cm. long, 8 to 12 mm. 

 thick; spores ellipsoid, 7.5 x 5 /x. 



Decayed crevices in bark, or knot-holes in living trees. 

 Thatchers, Wyrick. Wheaton, Gammon. A colony of over fifty 

 plants was found in. the hollow trunk of a living street tree, 

 Wheaton, October, 1900. The species is edible. 



Pholiota comosa Fr. (Plate IX, Fig. 1.) 



Pileus tawny, sprinkled with paler, superficial separating 

 scales, fleshy, convex then flattened, obtuse, viscous; flesh com- 

 pact, white. 



Lamellae adnate-decurrent, not much crowded, white, be- 

 coming fuscous clay-color. 



Stem solid, when young very compact, hard, somewhat bul- 

 bous then elongated, somewhat equal, fibrillose, white. Ring 

 more or less in the form of a cortina, floccose, moderately per- 

 sistent. 



On decorticated log of Ulmus americana. Woods, River 

 Forest. October, 1903. Identified by Prof. Peck. The spores 

 in mass on white paper are rich umber, not " fuscous-ferruginous " 

 as above described. They measure 10 x 6 /x. 



INOCYBE. 



Universal veil somewhat fibrillose, concrete with the cuticle 

 of the pileus, often free at the margin in the form of a cortina; 

 lamellae somewhat sinuate, changing color; spores rough or even, 

 fuscous-ferruginous.
