upward, firm, solid, fibrillose, slightly mealy-squamulose at 
the top, whitish or subconcolorous. 
Height 1’-2’, breadth of pileus 6’-18”, diameter of stipe 
2’'-3'". Under pine trees. Albany. October and November. 
A gregarious plant, with a meal-like flavor. The margin of 
the pileus sometimes has a paler appearance than the rest, 
from the absence or diminished density of the squamule, 
*20. AGARICUS PERSONATUS FY. 
Pileus thick, fleshy, convex, even, smooth, moist, pallid or 
cinereous, tinged with pale violet or lilac ; lamelle close, nar- 
row, rounded at the inner extremity, narrowed outwardly, 
whitish, often tinged with pink or violet; stipe stout, solid, 
whitish or concolorous fibrillose, slightly thickened at the 
base.

21. AGARICUS ALBOFLAVIDUS 2. Sp. 
Pileus at first convex, with the margin incurved, then 
expanded or slightly depressed, moist, smooth, even, white, 
in exposed places becoming yellowish; lamelle close, nar- 
row, thin, emarginate and decurrent with a tooth; stipe 
whitish, equal, solid, striate-fibrillose, with a thin, tough 
cuticle. 
Height 3’-4’, breadth of pileus 2’-3’, stipe about 3” thick. 
Ground in woods and open fields. Sandlake and North 
Elba. August. 
The pileus is sometimes slightly and broadly umbonate. 
Subgenus — Clitocybe. 
Stem elastic, with a fibrous outer coat; gills decurrent, or 
acutely adnate.— Berk. Outt. 
The form of the pileus in this subgenus is commonly that of 
an inverted cone, or, from the depression of the center in the 
thin species, of a funnel. The lamelle are decurrent or acutely 
attached to the stem, which is of a soft or spongy texture with- 
in, and destitute of an annulus. The veil, which is marginal 
and more or less perceptible in the preceding subgenus, in this 
is seldom noticeable.
