REPORT OF THE BOTANIST. 95 



Agaricus (Hebeloma) infldus n. sp. 



Pileus firm, campanulate or expanded, subumbonate, 

 slightly squamulose on the disk, often split on the margin, 

 whitish, lamellae close, pallid becoming cinnamon-brown ; 

 stem equal or slightly bulbous-thickened at the base, min- 

 utely furfuraceous, hollow, colored like the pileus ; spores 

 globose, rough with little nodules, .0003' in diameter. 



Plant about 2' high, pileus 6 // -12 // broad, stem l"-2" 

 thick. 



Mossy ground in swampy woods. Adirondack - Mts. 

 Sept. 



This species bears some resemblance to A. geophyllus, 

 but the slightly squamulose pileus and the rough spores 

 readily separate it. The margin of the pileus is sometimes 

 deeply split, the radiating lobes giving a stellate appear- 

 ance to the pileus. 



Agaricus (Hebeloma) fuscodisctjs n. sp. 



Pileus at first subviscid, conical, covered with blackish- 

 brown fibrils, then campanulate or expanded, umbonate, 

 whitish, the disk remaining blackish-brown ; lamellae close, 

 whitish then brownish, minutely rough on the edge ; stem 

 equal, solid, whitish and pruinose at the top, elsewhere 

 brownish, fibrillose ; spores .00035' long, .00018' broad. 



Plant l'-3' high, pileus 6"-12" broad, stem l"-2" thick. 



In an old pasture under trees. Forestburgh. Sept. 

 (Plate 1, figs. 3-6.) 



The somewhat viscid pellicle is separable. The odor 

 resembles that of chestnut blossoms. 



Agaricus (Hebeloma) fragilior n. sp. 



Small, fragile, pale grayish ochre ; pileus thin, convex, 

 then expanded or centrally depressed, sometimes irregular 

 or wavy on the margin, at first minutely squamulose 

 lamellae close, when young a little paler than the pileus, 

 minutely eroded on the edge ; stem slender, squamulose, 

 hollow, often expanded at the base into a thin disk. 



Plant about 1' high, pileus 3"-6" broad, stem scarcely 

 1" thick. 



Damp, decaying leaves in water holes of swamps. Indian 

 Lake. July. 



The minute scales of the pileus easily rub off and they 

 disappear with age. They sometimes project from the mar- 

 gin in a fimbriate manner.
