Plant csesiDitose; pileus 1 to 1.5 in. broad; stem 1 to 2 in. long, 1 to 

 2 lines thick. 



A single tuft of this peculiar species was found growing at the base 

 of an apple tree in the Catskill mountains, in September. The species 

 is remarkable for the copious bright colored spores which were so 

 thickly dusted over the pilei of the lower specimens as to conceal the 

 real color of the surface. They are quite as bright as and a little 

 longer than those of the preceding species. The general aspect of the 

 plant with its dark colored lamellse is suggestive of some species of 

 Hypholoma or Psilocybe, but the color of the spores requires its inser- 

 tion in this place. 



Clitopilus csespitosus n. sp. 



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

 nearly plain, fragile, often irregular or eccentric from its tufted mode 

 of growth, glabrous but with a slight silky luster, whitish, flesh white, 

 taste mild; lamellae narrow, thin, crowded, often forked, adnate or 

 slightly decurrent, whitish, becoming dingy or brownish-incarnate; 

 stem csespitose, solid, silky-fibrillose, slightly mealy at the top, white; 

 sj)ores very pale incarnate, .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. Catskill mountains. Sej^tember. 



This is a large, fine species, very distinct in its csespitose 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. 



Pholiota minima, n. sp. 



Pileus membranous, hemispherical or campanulate, umbonate, 

 glabrous, hygrophanous, brown and striatulate when moist, pale 

 buff or yellowish-white when dry; lamellae rather close, subventricose, 

 adnexed, ferruginous; stem slender, solid, glabrous, shining, similar 

 to the pileus in color, annulus near the middle, slight, evanescent; 

 spores elliptical, .0003 in. long, .0002 broad. 



Pileus 2 to 4 lines broad; stem 8 to 12 lines long, .5 line thick. 



Among Polytrichum. Catskill mountains. September. 



The species is distinguished from P. mycenoides, to which it is 



closely related, by its smaller size, paler color, umbonate pileus and 



solid stem. 



InocyTbe iilbrillosa, n. sp). 



Pileus thin, convex or nearly plain, obtuse or subumbonate, densely 

 fibrillose, tawny, the disk usually darker in color and adorned with 

 appressed fibrillose scales; lamellae close, adnate, at first yellowish or
