Mycologia 
An exceedingly variable species, usually white and scaly and 
often with a chlorin odor, occurring in the open or in thin 
woods throughout most of the United States. It has been 
considered edible, but Ford finds that it contains a small quantity 
of the deadly amanita-toxin found in V enenarins phalloides and 
it should therefore never be eaten. The variety here figured is 
one of the rarest forms assumed by this species in America, 
representing Agariciis echinocephalits Vitt. and Agaricits oniistus 
Howe. 
Venenarius glabriceps (Peck) Murrill 
Smooth-capped Amanita 
•Plate 190. Figure 2. X i 
Pileus thin, ovoid, becoming broadly convex or centrally de- 
pressed, 5—10 cm. broad; surface glabrous, viscid when moist, 
rarely adorned when young with a few patches of the ruptured 
volva, white or yellowish-white, sometimes slightly brownish at 
the center, margin usually finely striate ; context white ; lamellae 
thin, crowded, free, unequal, white ; spores globose, smooth, 
hyaline, 7.5 ju. ; stipe long, slender, stuffed, glabrous or floccose- 
squamulose, white, bulbous at the base, 7.5—15 cm. long, 6-12 
mm. thick ; annulus thin, white, sometimes appendiculate or 
evanescent ; volva adnate, marginate, definitely circumscissile. 
This rare and elegant species occurs among fallen leaves in 
woods in New York state. The surface is usually glabrous 
from the first,, as in white and yellow forms of V. phalloides. 
Peck says his Amanita phalloides striatiila is a small variety of 
this species.

Amanitopsis albocreata Atk. 
White-booted Vaginata 
Plate 190. Figure 3. X i 
Pileus convex to expanded, 5-8 cm. broad ; surface viscid, with 
floccose volval patches which usually mostly disappear with age, 
white with yellow center, or at times entirely pale-yellow, margin 
finely striate and minutely tuberculate ; context thin, white ; lamel- 
lae free or slightly adnexed, rounded in front, narrowed behind, 
floccose on the edges; spores globose, smooth, hyaline, 7—10/4; 
stipe cylindric or slightly tapering upward, abruptly bulbous, 
minutely floccose or farinose, white, hollow, 10-13 cm. long, 6-12
