Figure 124, page 69
PILEUS 1 54-4 (5) in. broad, convex, becoming expanded, often with a
broad obtuse umbo, dark brown, smoky brown, or olive-brown, paler on the
margin, usually somewhat streaked with innate fibrils, viscid, decorated with
whitish or pallid brownish, floccose warts or patches which may disappear,
sometimes faintly striate on the margin, flesh thin except on the margin,
white, tending to stain reddish brown, odor faint, lamellae free or almost so,
creamy white, close, rather broad, narrowing toward the stipe, with many
short lamellulae interspersed, stipe 3-6 in. long, i/4-% in. thick, with an
abrupt, hard, marginate bulb whose margin splits longitudinally in a very
characteristic manner, equal or tapering upward above the bulb, stuffed with
a pith, subglabrous or minutely scurfy, white, staining reddish brown from
the base upward, annulus large, membranous, collapsing against the stipe,
white or pallid, staining reddish brown, volva dingy white to pallid brownish,
breaking up into membranous-floccose fragments, some of which may cling to
the pileus or bulb margin, usually leaving no trace on the bulb, spores amyloid,
smooth, white, globose, 7-9 (10) /x-
In groups or scattered, on the ground in woods. July-Sept.
Bruises and wounds of the pileus and stipe stain reddish brown. The mar-
ginate bulb and globose spores distinguish this species from A. rubescens.
However, it is very easy to confuse these two species, and, as one is poisonous
and the other edible, a mistake might be serious. A. brunnescens var. pallida
Krieger is a whitish form which Singer has called Amanita aestivalis.
