AMANITA
pallid or grayish on the bulb, usually separable at the margin, often leaving a
few friable, gray patches on the pileus, and around the stipe base, spores
amyloid, smooth, white, globose, 7-9 /z.
Sohtary or in groups of several on the ground in woods. Aug.-Oct.
Infrequent.
The brown pileus, ashy gray annulus and soft, globose bulb are the dis-
tinguishing marks of this species. A. tomentella Krombh. is said to differ in the
densely powdery, gray coating of the pileus and stipe. A form answering to
the description of A. tomentella is occasionally collected and seems distinct
from the usually glabrous A. porphyria. Whether or not this is a variation of
A. porphyria is a question. A. porphyria often bears a few fragments of gray
pulverulence on the pileus and occasionally it has a rather large powdery
volval patch. A. spreta Peck is another brown to umber species in which the
stipe is equal throughout and not bulbous at the base.

PILEUS 2-6 in. broad, at first ovoid, expanding to convex or with a broad
obtuse umbo, variable in color, usually dingy reddish or dull reddish brown,
often with muddy brown or olive-umber shades present, shghtly viscid,
adorned with numerous, floccose, grayish or dirty pinkish scales which are
readily washed off, nonstriate or the extreme margin indistinctly striate.
FLESH thin, soft, white, staining reddish, odor not distinctive, lamellae free or
scarcely attached, close to crowded, moderately broad, narrowing toward the
stipe, dingy white, staining reddish, stipe stout, sometimes slightly excentric,
3-8 in. long, )4-% in. thick, swollen at the base, subequal or tapering up-
ward, stuffed, subglabrous to minutely fibrillose, staining dingy pink to
reddish, annulus large, membranous, fragile, collapsing against the stipe,
dingy white or pale greenish yellow, staining pinkish, volva fragile, gray,
tinged sordid reddish, breaking up into scales on the pileus, usually lacking
or almost so on the stipe base as most of the fragments remain in the soil.
spores amyloid, smooth, white, ellipsoid, 7-9 (10) X 5-7 }i.
Sohtary or scattered, on the ground in woods. July-Sept.
This is one of the edible species of Amanita, but the danger of confusing
it with the poisonous A. brunnescens is great. Wounds and bruises in A. rubescens
stain a sordid reddish color, while in A. brunnescens the stains are more
reddish brown. A. brunnescens has a marginate bulb and globose spores.
A. flavorubescens also stains reddish, but the dull yellow coloring, especially
in the pileus margin, should distinguish it.
