Agaricus dealbatus Sow. 



Grassy pastures. Brewerton. Sept. 



Agaricus odorus Bull. 



Ground in woods. Gansevoort. Aug. 



In our specimens the lamellae are close and white, and the pileus loses its 

 green color with age. 



Agaricus (Clitocybe) anisarius n. sp. 



Pileus convex, then expanded, greenish-gray with the margin incurved, 

 then grayish or whitish, adorned with minute innate fibrils, slightly pruinose 

 and substriate on the margin ; lamellae adnate or decurrent, narrow, crowded,, 

 white ; stem subequal, firm, hollow, whitish ; spores subelliptical, .00025' 

 long ; odor weak but pleasant, anise-like. 



Plant 2-4' high, pileus 1.5-3' broad, stem 2 '-3 ' thick. 



Ground in woods. Gansevoort. Aug. 



This is closely related to A. connexus, from which' it is easily separated by 

 the hollow stem. 



Agaricus (Clitocybe) leptolomus n. sp. 



Pileus thin, plane or infundibuliform, umbilicate, hygrophanous, smooth r 

 creamy-white when moist, white when dry, the margin very thin ; lamellae thin, 

 narrow, crowded, some of them forked, decurrent, white ; stem equal, smooth, 

 generally curved or flexuous, stuffed, colored like the pileus, white-villous at 

 the base; spores very minute, subelliptical, .00012' long. 



Plant gregarious or subcaespitose 2'— 3' high, pileus about 2' broad, stem 

 1 '-2' thick. 



Decaying prostrate trunks in woods. Indian Lake. Aug. 



The width of the lamellae is about equal to the thickness of the flesh of the 

 pileus. They taper gradually toward each end, where they are very narrow. 

 The species may be distinguished from A. truneicola by its hygrophanous 

 umbilicate pileus. The stem is sometimes eccentric. 



Agaricus (Collybia) cremoraceus n. sp. 



Pileus thin, submembranaceous, convex or campanulate, obtuse, dry, 

 slightly silky, dingy cream color, the margin sometimes wavy ; lamellae 

 broad, ascending, ventricose, with a decurrent tooth, whitish ; stem slender, 

 slightly silky, stuffed or hollow, pallid or subconcolorous ; spores broadly 

 elliptical or subglobose, .00025' long, .0002' broad. 



Plant 1.5-2 high, pileus 6"-12'' broad, stem about 1" thick. 



Ground in woods. Gansevoort. Aug. 



Agaricus (Collybia) hygrophoroides n. sp. (Plate II, figs. 21-24.) 



Pileus subconical, then convex or expanded, smooth, hygrophanous, red- 

 dish or yellowish-red when moist, paler when dry; lamellae sub-distant, 

 rounded behind or deeply emarginate, eroded on the edge, whitish ; stem nearly 

 equal, striate, stuffed or hollow, whitish; spores subelliptical, .0002'-00025' 

 long, .00016' broad.
