Report of the Botanist. 63 



both pileus and stems are sprinkled with a yellow ])nlverulent 

 coating. When old, the plant becomes much faded. The fingers 

 are stained in handling it. The lamellse in our specimens were 

 yellow^ with an orange-colored edge. Spores ellipitical, -g-gVo' long. 



Agaricus hjematopus Pers. 



Old logs in woods. Garrisons. Grreig, etc. June, September. 



Agaeicus Tintinnabtjlum Fr. 



On an old beech stump. Knowersville, Albany county. May. 



Agaricus (Mycena) leptophtllus n. sp. 



Pileus thin, campanulate or convex, subpapillate, smooth, stria- 

 tulate when moist, pale reddish-yellow, the disk brighter colored ; 

 lamellae close, narrow, widest at the middle, pointed at the outer 

 extremity, sharply uncinate at the inner, whitish or yellow with 

 a flesh-colored tint; stem slender, tough, hollow, smooth, w^hitish. 



■Plant 1-1.5' high, pileus d'-5' broad, stem .5'' thick. 



Old mossy logs and rotton wood in woods. Greig. September. 



The papilla of the pileus is sometimes absent. 



Agaricus (Omphalia) Fibuloides n. sp. 



Pileus fleshy but thin, convex, deeply umbilicate, smooth, hygro- 

 phanous, dull orange-colored and striatulate when moist, paler 

 when dry ; lamellae rather close, arcuate, long-decurrent, venose- 

 connected, white ; stem equal, smooth, hollow, nearly the same 

 color as the pileus, with a white mycelium at the base ; spores sub- 

 elliptical, 3o'o o' long. 



Plant l'-2' high, pileus 6"-10'' broad, stem scarcely 1" thick. 



Burnt mossy ground in a pasture. Greig. September. 



It resembles A. Fibula in its coloration, but its larger size, short 

 stem, and venose-connected lamellae readily distinguish it. 



Agaricus (Omphalia) LiLAcmus n. sp. 



Pileus submembranaceous, convex, deeply umbilicate, smooth, 

 viscid, hygrophanous, dull yellow with a slight greenish tinge and 

 striatulate when moist, bright sulphur-yellow when dry ; lamellae 

 rather close, arcuate, decurrent, pale lilac; stem equal, smooth, 

 hollow, viscid, yellowish with a pale lilac-colored mycelium at the 

 base. 



Plant about 1' high, pileus 6"-9" broad, stem .5" thick. 



Old logs in woods. Trenton Falls. Sept. (Plate 1, figs. 10-13.) 



A very distinct species, remarkable for the peculiar hue of the 

 lamellae and the mycelium. The color of the latter is retained in 

 the dried specimens before me.
