the margin is generally even, bnt sometimes it is found distinctly striate; 
the flesh is white, but changes to reddish when bruised or broken. The 
base of the stipe is thickened or bulbous, but there is no trace of the 
volva in the fully-grown plant.

JS T o. 2. 
Pileus convex, areolate-verrucose ; warts soft, angular, pyramidal; 
stipe flocculose-scaly, bulbous at the base ; annulus thick, at length dis¬ 
tant ; lamellae remote, ventricose. In moist and sandy woods ; common. 
South Carolina, Curtis. “Pileus 2-^—3 inches across, areolate, with a 
wart in the center of each areola, those towards the margin consisting 
of soft threads meeting in a point, but sometimes simply flocculent; the 
central warts angular, pyramidal, truncate, disc lored. The warts are 
not hard and rigid as in A. nitidus .” 
f. Warts of the pileus thick and hard.

Vol. I, p. 9; Cooke, Illust. pi. 70; Fries, leones Selectee, pi. 12. 
Pileus convex, then plane, firm, covered with dark warts which are 
thick, angular and indurated; margin wholly even ; the flesh white ; 
stipe stuffed, conic-attenuate, scaly; annulus lacerate, fugacious; lamellae 
free, very broad, ventricose, white. In shady woods. California, Hark- 
ness. Pileus 3—5 inches in diame.ter; stipe three inches long. The 
pileus is whitish, rarely inclining to yellow or greenish ; the stipe is 
bulbous at the base. 
18. Agaricus aspjer, Fries. Hym. Eur., p. 24; Stevenson, B. F., 
Vol. I, p. 9; Cooke, Illust. pi. 10. 
Pileus convexo-plane, scabrous, with minute, pale warts, which are 
crowded and subirmate ; the margin even ; the flesh compact, brownish 
under the cuticle; stipe stuffed, then hollow, attenuate; the annulus 
entire, distant; lamellae rotundate-free ; spores .008 x .0065 millim. In 
beech woods ; rare. Carolina, Schweinitz; Minnesota, Johnson. Pileus 
2—3 inches in diameter, stipe 2—3 inches long. The pileus is of a sooty- 
olivaceous color, the stipe varies, short and attenuate or longer and 
cylindric. 
D. Volva flocculose and wholly evanescent, the pileus therefore 
naked and free from scales and warts.

Stevenson, B. F., Vol. I, p. 10; Cooke, Illust. pi. 17; Fries. leones 
Selectae, pi. 13. 
Pileus globose, then convexo-plane, soft, naked, alutaceous, flesh- 
color; the margin even; stipe stuffed, bulbous, scaly; the annulus 
superior, ample ; lamellae free, becoming pale. In pine woods. Carolina, 
Curtis. Pileus 3—4 inches in diameter, stipe 4—6 inches long. The color 
of the pileus varies to pale and reddish*yellow ; the lamellae sometimes 
inclines to olivaceous.
