Technical Description. (t.b.d.)

BRIEF DESCRIPTION: The following description is based on Reid (1980).

The cap of Amanita griselloides is 60 mm wide, plano-convex, silvery-gray, with a smooth margin. The cap is covered with thin, felty-fibrillose, gray remnants of volva "overlain by a scanty, white, arachnoid weft." 

The gills are white.

The stem is up to 70 x 10 mm, the base is up to 14 mm, and whitish. Both the ring and volva are lacking.

The spores measure 8.2 - 12.5 x 6.0 - 7.0 (-8.5) µm and are ellipsoid and amyloid. Clamps are absent at bases of basidia.

Originally described from the state of Western Australia.

Reid says Amanita griselloides is "virtually indistinguishable in the field from Amanita grisella E.-J. Gilbert & Clelend" and points out the two species are separable by spore shape. The spider-web-like upper layer of volva is unknown elsewhere in Amanita sect. Validae. Reid described both the holotype and a second specimen that he believes was contaxic; both collections have the unusual, entirely hyphal upper layer of the volva. -- R. E. Tulloss
