In woods and thickets, September and October. Pileus 2-4 in. broad, 

 stipe 1-3 in. long, f in. 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 lias an oily appearance on the surface, but is watery not viscid; 

 the stipe is often ver}' 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 as in Entoloma. 



c. Pileus brown or blackish. 



28. A. CERiNDS, Pers. — Pileus flesh^'', convexo-plaue, obtuse or de- 

 pressed, becoming glabrous. Stipe stuffed, fibrillose-striate, glabrous at 

 the base, often brown. Lamelloe attached, seceding, close, j'ellow. 

 Spores oval, .0083 X. 0055 mm. 



In open woods about logs and rotten wood. Pileus 1^-2 in. broad, 

 stipe about 1^ in. long. The plant I have so referred has the stipe 

 brown-tomeutose; in other respects it agrees quite perfectly. 



29. A. MELALEDCUS, Pcrs. — Pileus fleshy, thin, convexo-plane, some- 

 what umbonate, glabrous, moist, growing pallid. Stipe stuffed, slender, 

 elastic, ratlier glabrous, whitish with a few dark fibrils, thickened at 

 the base. Lamella emarginate-attached, close, white. Spores uns^nu- 

 metrical, apiculate, .006 X -004 mm. 



In woods in wet weather and on grassy grounds. Pileus 1^-3 in. 

 broad, the stipe 2-3 in. long. The pileus varies in color from a soot^'- 

 black when fresh and wet to pale when drj^; tiie lamellae and stipe are 

 white. 



Note. — Our species of Tricholoma are remarkabl}' 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. 

 Schumacher i, 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. 



Subgenus V. — Cutocyije, Fr. 



Spores white (except in No. 31). Stipe spong3'-stuffed, somewhat 

 elastic, externally fibrous. Margin of the pileus involute. Lamelloe 

 attenuate behind, adnate or decurrent, never sinuate. Fungi mostly 

 terrestrial.
