edge, whitish, becoming ferrnginous-brown ; stem smooth, hollow, 

 slightly thickened at the base ; annulus thin, fugacious, sometimes 

 adhering to the margin of the pileus ; flesh white ; spores .00033 x 

 .0002 in. 



Plant 3-4' high, pileus 2-3' broad, stem 2'-4:'' thick. 



Ground. Center. June,. 



The surface of the pileus sometimes cracks into areas. The 

 taste is bitter. The color of the spores is not a decided brown, and 

 the plant might, with almost equal .propriety, be referred to the 

 subgenus Pholiota. 



Agaeicus (Htpholoma) phyllogenus Pech. 



Pileus firm, convex, sometimes slightly umbonate, hygrophanous, 

 reddish-brown when moist, alutaceous when dry ; lamellae plane, 

 broad, close, brown, white on the edge ; stem equal, fibrillose, 

 stufted or hollow, spreading out at the base into a thin flat disk ; 

 spores pale-brown, subglobose, .0002 in. in diameter. 



Plant 8"-12" high, pileus 2"-4r" broad, stem .5" thick. 



Fallen leaves in woods. Worcester. July. 



This is a very small but distinct species, remarkable for the disk- 

 like base of the stem b}^ which it is attached to the leaves on which 

 it grows. 



COPKINUS INSIGNIS Peolc. 



Pileus campanulate, thin, sulcate-striate to the disk, grayish 

 fawn color, the smooth disk sometimes cracking into small areas or 

 scales ; lamellae ascending, crowded ; stem hollow, slightly fibrillose, 

 striate, white; spores rough, .0004 x .00028 in. 



Plant 4'-5' high, pileus 2'-3' broad, stem 3" thick. 



About the roots of trees in woods. Worcester. July. 

 The species is remarkable for its rough spores. In size and 

 general appearance it bears some resemblance to G. atramentarius, 



COPKINUS ANGULATUS Peclc. 



Pileus submembranaceous, hemispherical or convex, plicate-sul- 

 cate, the disk smooth ; lamellae subdistant, reaching the stem, 

 whitish, then black ; stem equal, smooth, whitish ; spores com- 

 pressed, angular, subovate, .0004 x .00033 in. 



Plant l'-2' high, pileus 6"-12" broad, stem .5" thick. 



In woods. Croghan. September. 



The specific name has reference to the angular character of the 

 spores. These in shape have some resemblance to a very blunt 

 arrow-head, they being slightly excavated on each side of the base
