Clitopilus conissans, Pk. 



Dusted Clitopilus. 



Pileus thin, convex, glabrous, pale-alutaceous, often dusted by the 

 copious spores; lamellae close, adnate, reddish-brown; stem slender, 

 brittle, hollow, ciespitose, white; spores narrowly elliptical, .0003 in. 

 long, .00016 broad. 



Pilus 1 to 1.5 in. broad; stem 1 to 2 in. long, 1 to 2 lines thick. 



Base of an apple tree. Catskill mountains. September. 



Kemarkable for the copious bright rosy-red spores which are some- 

 times so thickly dusted over the lower pilei of a tuft as to conceal 

 their real color. The species is very rare. 



Spores very pale flesh-colored, merely tinted. 

 Clitopilus caespitosus, Pk. 

 Tufted Clitopilus. 



Pileus at first convex, firm, nearly regular, shining, white, then 

 nearly plane, fragile, often irregular or eccentric, glabrous but with a 

 slight silky lustre, even, whitish, flesh white, taste mild; lamellae nar- 

 row, thin, crowded, often forked, adnate or slightly decurrent, whitish, 

 becoming dingy or brownish-pink; stems ccespitose, solid, silky-fibril- 

 lose, slightly mealy at the top, white; spores .0002 in. long, .00016 

 broad. 



- Pileus 2 to 4 in. broad; stem 1.5 to 3 in. long, 2 to 4 lines thick. 



Thin woods and pastures. Ulster county. Sept. 



This is a large, fine species, very distinct by its caespitose habit, 

 white color and very pale sordid-tinted spores. But for the color of 

 . these the plant might easily be taken for a species of Clitocybe. The 

 tufts sometimes form long rows. 



Clitopilus Noveboracensis, Pk. 



New York Clitopilus. 



Pileus thin, convex, then expanded or slightly depressed, dingy white, 

 rimose-areolate or concentrically rivulose, sometimes obscurely zonate, 

 odor farinaceous, taste bitter; lamellae narrow, close, deeply decurrent, 

 some of them forked, white, becoming dingy, tinged with yellow or 

 flesh-color; stem equal, solid, colored like the pileus, the mycelium 

 white, often forming white branching root-like fibres; spores globose, 

 .00016 to .0002 in. broad. 



Var. brevis. Margin of the pileus, in the moist plant, pure white; 

 lamellae adnate or slightly decurrent; stem short. 



Pileus 1 to 2 in. broad; stem 1 to 2 in. long, 1 to 3 lines thick.
