BRIEF DESCRIPTION: The following is based on the description in Dr. Bas' (1969) thesis on section Lepidella.  The flesh throughout the fruiting body is white and unchanginge when cut or bruised.

The cap of A. straminea is about 40 - 56 mm wide, white, convex to nearly plane with a slightly depressed center and a margin that is nonstriate and slightly appendiculate.  The volva is present as thin, white pulverulence.  The volva disappears with age.

The gills are adnexed to narrowly adnate, rather crowded, more or less straw yellow with a white edge when young, and rather broad (up to 10 mm wide).  Short gills are attenuate.

The stem is about 40 - 58 x 6 -10 mm, equal, white, solid, subpulverulent to subfibrillose.  The stem bears an annulus that is subapical, pendant, membranous, and white.  There are no obvious volval remains on the stem's immarginate basal bulb (15 - 20 x 8 - 12 mm).

The spores measure 10.5 - 12 (-13.5) x (6-) 6.5 - 8 µm and are amyloid and ellipsoid to elongate.  The spore print is yellowish.  Clamps are not present at bases of basidia.

Amanita straminea was described from "under shrubs" from the state of South Australia, Australia.

Bas placed this species in his stirps Straminea.  The other taxon currently placed in this stirps is A. californica Bas nom. prov., A. gracilenta A. E. Wood, and A. griseibrunnea O. K. Mill.  For more about the present species, the reader may wish to view the page for A. kammala Grgur.  As more and more Australian taxa are described, stirps Straminea appears more and more to be Australian in origin.  Amanita californica should probably be reexamined to answer the question whether it appears closely related to the growing list of Australian species in the stirps.
