Technical description (t.b.d.)

BRIEF DESCRIPTION: Description based on Reid (1980).

The cap of Amanita gossypino-annulata is 22 - 40 mm wide, convex then plano-convex, pale fawn, with a smooth margin.  The cap has a large, thin, white, felt-like patch of volval tissue, disappearing with age.

The gills are white.

The stem is about 30 x 5 mm, cylindric, white, with a markedly abrupt, marginate bulb, up to 12 mm wide. The ring is "well-developed but thick and cottony."  Reid found no evidence of volva on the bulb.

The spores measure 7.0 - 10.0 x 6.2 - 9.0 µm and are globose to subglobose, occasionally broadly ellipsoid and amyloid  Clamps are present at base of basidia.

This species was originally described from the state of Victoria, Australia.  This species is known only from the type.

According to the key of Bas (1969), this species may best fit in Bas' stirps Grossa, near A. farinacea (Cooke & Massee) Cleland & Cheel.  The latter may differ in the microscopical details of the volva. -- R. E. Tulloss
