Technical Description. (t.b.d.)

BRIEF DESCRIPTION: Description based on Reid (1980).

The cap of Amanita hiltonii is up to 60 mm wide, becoming plano-convex, creamy-white or silvery, and completely covered with cottony-floccose volval remnants which may form low, indistinct warts, especially toward the center.

The gills are off-white, becoming pale yellow in older specimens and on drying.

The stem is up to 50 x 20 mm, white, clavate with a slightly rooting base. The ring is distinct, membranous, narrow and easily lost. The volva is not apparent on stem base.

This species has a nut like smell.

The spores measure 7.0 - 9.5 (-10.0) x 4.8 - 6.2  µm and are ellipsoid and amyloid. Clamps are frequent at base of basidia.

This species was originally described from Perth in the state of Western Australia. This species occurs in laterite soil. Reid knew this species from two collections.  

Among the stirpes designated by Bas (1969) the present species is most likely to fall in stirps Grossa. It appears somewhat close to A. grossa (Berk.) Sacc. and to A. subalbida Cleland, but it's spores are too small in both cases.  -- R. E. Tulloss
