Amanita brunneomaculata. The fruiting bodies
of Amanita brunneomaculata are medium-sized.
cap
The cap is 50 – 90 mm wide, plano-convex to
planar, whitish, and has a brownish to brown
spot when mature. The volva is present as
fluffy to patchy, whitish to brownish
remnants, which are easily broken when
mature. The cap’s margin is non- or radially
grooved and has material hanging from
its edge. The flesh is white.
gills
The gills are free, crowded, and white, but
become grayish, gray-brown, brownish
to brown when dried. The short gills
are truncate and plentiful.
stem
The stem is 50 – 130 × 10 – 22 mm, nearly cylindrical or
narrowing upwards, white, brownish to brown,
covered with concolorous fluffy
squamules. The stem lacks a basal bulb. At
the stem's base, the volva is saccate,
15 – 50 × 15 – 40 mm, and membranous; the outer surface
is white, brownish to brown, and the inner surface
is brownish to brown. The ring hangs
from a region 30 – 40 mm below the stem's
top and is fluffy, whitish and fugacious.
