In woods and thickets, September and October. Pileus 2-4 in. broad, 
stipe 1-3 in. long, 2in. thick. The whole plant in its prime is of a violet 
or lilac hue; this changes with age to a pallid or dirty white color. The 
pileus has an oily appearance on the surface, but is watery not viscid; 
the stipe is often very short and thick for the size of the pileus. The 
margin of the pileus is at first involute and villous-pruinose. The spores, 
although reddish, are regular in shape, and not angular asin Entoloma. 
c. Pileus brown or blackish. 
28. A. ceRINUS, Pers.—Pileus fleshy, convexo-plane, obtuse or de- 
pressed, becoming glabrous. Stipe stuffed, fibrillose-striate, glabrous at 
the base, often brown. Lamelle attached, seceding, close, yellow. 
Spores oval, .0083 x .0055 mm. 
In open woods about logs and rotten wood. Pileus 14-2 in. broad, 
stipe about 14 in. long. The plant I have so referred has the stipe 
brown-tomentose; in other respects it agrees quite perfectly. 
29, A, MELALEUCUS, Pers,—Pileus fleshy, thin, convexo-plane, some- 
what umbonate, glabrous, moist, growing pallid. Stipe stuffed, slender, 
elastic, rather glabrous, whitish with a few dark fibrils, thickened at 
the base. Lamelle emarginate-attached, close, white. Spores unsym- 
metrical, apiculate, .006.004 mm. 
In woods in wet weather and on grassy grounds. Pileus 14-3 in. 
broad, the stipe 2-3 in. long. The pileus varies in color from a sooty- 
black when fresh and wet to pale when dry; the lamelle and stipe are — 
white. 
Notr.—Our species of Tricholoma are remarkably few in number, 
and the individuals very scarce. Not a single species occurrs in 
Lea’s Catalogue. I am disposed to think I have had specimens of A. 
schumacheri, Fr., but they are not figured, and need verification. Being 
so few in number, I have given them an artificial arrangement, in order 
simply to facilitate their determination. 
SusGENus V.—CuirocyseE, Fr. 
Spores white (except in No. 31). Stipe spongy-stuffed, somewhat 
elastic, externally fibrous. Margin of the pileus involute. Lamelle 
attenuate behind, adnate or decurrent, never sinuate. Fungi mostly 
terrestrial.
