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

Figures 137, 138, page 71<br />
PILEUS 2-6 in. broad, at first ovoid, expanding to convex or with a broad<br />
obtuse umbo, variable in color, usually dingy reddish or dull reddish brown,<br />
often with muddy brown or olive-umber shades present, shghtly viscid,<br />
adorned with numerous, floccose, grayish or dirty pinkish scales which are<br />
readily washed off, nonstriate or the extreme margin indistinctly striate.<br />
FLESH thin, soft, white, staining reddish, odor not distinctive, lamellae free or<br />
scarcely attached, close to crowded, moderately broad, narrowing toward the<br />
stipe, dingy white, staining reddish, stipe stout, sometimes slightly excentric,<br />
3-8 in. long, )4-% in. thick, swollen at the base, subequal or tapering up-<br />
ward, stuffed, subglabrous to minutely fibrillose, staining dingy pink to<br />
reddish, annulus large, membranous, fragile, collapsing against the stipe,<br />
dingy white or pale greenish yellow, staining pinkish, volva fragile, gray,<br />
tinged sordid reddish, breaking up into scales on the pileus, usually lacking<br />
or almost so on the stipe base as most of the fragments remain in the soil.<br />
spores amyloid, smooth, white, ellipsoid, 7-9 (10) X 5-7 }i.<br />
Sohtary or scattered, on the ground in woods. July-Sept.<br />
This is one of the edible species of Amanita, but the danger of confusing<br />
it with the poisonous A. brunnescens is great. Wounds and bruises in A. rubescens<br />
stain a sordid reddish color, while in A. brunnescens the stains are more<br />
reddish brown. A. brunnescens has a marginate bulb and globose spores.<br />
A. flavorubescens also stains reddish, but the dull yellow coloring, especially<br />
in the pileus margin, should distinguish it.<br />
