114 Forty-second Annual Report on the 



Tricholoma microcephalum, Karst. 



Grassy ground in meadows and pastures. North Elba. Sept. 



The specimens have the colors of T. melaleucum, but the spores 

 agree better with those of T. microcephalum. The fresh plant bears 

 some resemblance to small dark colored forms of Collybia radicata or 

 to small G. fuhginella. The lamellae retain their white color in the 

 dried state. 



Clitocybe media, n. sp. 



[Plate 1. Figs. 9-12.] 



Pileus fleshy, convex, becoming plane or. Rlightly depressed, dry, 

 dark grayish-brown, the margin often wavy or irregular, flesh white, 

 taste mild; lamellae broad, subdistant, adnate or decurrent, whitish, 

 the interspaces somewhat venose; stem equal or but slightly thick- 

 ened at the base, solid, elastic, not polished, colored like or a little 

 paler than the pileus; spores elliptical, .0003 in. long, .0002 broad. 



Pileus 2 to 4 in. broad; stem 1 to 2 in. long, 4 to 8 lines thick. 



Mossy ground in deep woods. North Elba. Sept. 



This species is intermediate between G. nebularis and G clavipes. 

 In its general appearance, and in the character of the pileus and stem, 

 it resembles G. nubularis, but in the character of the more distant 

 lamellae and in the size of the spores it is nearer G. clavipes, of which 

 it might perhaps be regarded as a variety. Two forms are distinguish- 

 able. In one the lamellae are more distant, slightly rounded behind, 

 and adnate or abruptly terminated, in the other they are closer and 

 more distinctly decurrent. The plant is edible. G. clavipes is said to 

 be inedible on account of its spongy substance. 



Clitocybe gallinacea, Scop. 

 Woods. North Elba. Sept. Both the stem and the pileus appear 

 as if pruinose or slightly mealy. The taste is bitter and unpleasant. 



Clitocybe tumulosa, Kalchb. 



Groves of spruce and balsam. North Elba. Sept. Densely 

 caespitose. Edible. 



Clitocybe angustissima, Lasch. 

 Low wet ground in woods. North Elba. Sept. 



Clitocybe subditopoda, n. sp. 



Pileus thin, convex or nearly plane, umbilicate, hygrophanous, 

 grayish-brown and striate on the margin when moist, paler when dry, 

 flesh concolorous, odor and taste farinaceous; lamellae broad, close, 

 adnate, whitish or pale cinereous; stem equal, glabrous, hollow, colored
