Amanita spreta or the hated amanita[1] is an inedible species of the genus Amanita.[2]

Description

A. spreta is usually distinguished by its grayish brown cap with dark, radial streaks; its medium to large size, the presence of a ring on the upper stem, and its stem base, in which it features a white, sacklike volva and is not prominently swollen. Its ellipsoid, inamyloid spores also help to distinguish it.[3]

Cap

The

striate margin. The volva is either absent or present as white to pale gray, scant, irregular patches, soft to smooth, easily removable, and membranous. The flesh is white, pale brown under the cap skin in the center, is 8–17 millimetres (1212 in) thick over the stem, and is thinning evenly nearing the margin.[4]

Gills

The gills are free, receding at maturity, very crowded to crowded, pale cream to cream to white, 8–19 mm broad, broadest at the midpoint, anastomosing, with faint and short decurrent lines on the top of the stem, and with a minutely powdery edge. The short gills are truncate to rounded truncate to subtruncate, unevenly distributed, of diverse lengths, and plentiful (sometimes more plentiful than full-length gills). The short gills can be adjacent to the stipe or adjacent to the cap margin or neither.[4]

Stem

The stem of A. spreta is 5–10 cm long, up to 2 cm thick, tapering slightly to apex, is whitish, sometimes discoloring a little brownish; finely hairy to shaggy; with a white, skirtlike ring that may discolor brownish; with a slightly enlarged but not bulbous base that is set in a sack-like, flaring or lobed, white volva.[3]
