Amanita submembranacea (3)
|Amanita submembranacea has a cap up to 115 mm wide; it is strongly olivaceous with a pallid margin, at least at first. Marginal striations occupy less than one fourth of the pileus radius.|
Gills are free, not very crowded, and off-white tending to gray or brown with age; the short gills are truncate to subtruncate, plentiful, and unevenly distributed.
Its stem is exannulate and has a sheathing, submembranous volva at its base. This volva rapidly becomes gray after it has been split to expose the pileus, and it often has the appearance of canvas with flakes of old paint on it.
The spores measure (8.3-) 9.5 - 13.0 (-14.5) x (7.3-) 9.0 - 12,0 (-13.0) Ám and are globose to subglobose (infrequently broadly ellipsoid) and inamyloid. Clamps are absent from bases of basidia.
