both pileus and stems are sprinkled with a yellow pulverulent 
coating. When old, the plant becomes much faded. The fingers 
are stained in handling it. The lamellze in our specimens were 
yellow with an orange-colored edge. Spores ellipitical, 54,5’ long.

Agaricus (OMPHALIA) FrsvLorpEs v. sp. 
Pileus fleshy but thin, convex, deeply umbilicate, smooth, hygro- 
phanous, dull orange-colored and striatulate when moist, paler 
when dry; lamelle 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, 575,’ long. j 
Plant 1'-2’ high, pileus 6’-10” broad, stem scarcely 1" thick. 
Burnt mossy ground ina pasture. Greig. September. 
It resembles A. /2bula in its coloration, but its larger size, short 
stem, and venose-connected lamellze readily distinguish it. 
Agaricus (OMPHALIA) LILACINUS 2. 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; lamelle 
rather close, arcuate, decurrent, pale lilac; stem equal, smooth,

Old logs in woods. Trenton Falls. Sept. (Plate 1, figs. 10-13.) 
A very distinct species, remarkable for the peculiar hue of the 
lamelle and the mycelium. The color of the latter is retained in 
the dried specimens before me.
