Technical Description. (t.b.d.)

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

The cap of Amanita luteofusca is 30 - 56 mm wide, convex then applanate, center slightly depressed, viscid when moist, pale umbrinous to gray-brown to grayer and darker  than Ridgeway's Pinkish-Buff. The volva is uniformly distributed flat scales that are farinose, pale-gray, most densely placed in the center, up to 3 mm wide. A thin, white layer of hyphae project from the edges of the larger scales. The flesh is thin.

The gills are moderately crowded, adnate, up to 9 mm broad, and white.

The stem is 56 - 80 x 5 - 10 mm, white, rather narrow, stuffed then finally subhollow, moderately attenuate upwards, minutely fibrillose, with an indistinct volva. The base of the stem is narrowly bulbous. The ring is membranous, sometimes left on cap margin.

The spores measure 7.0 - 11.0 x 7.0 - 9.2 µm and are globose to subglobose to broadly ellipsoid and amyloid. Clamps are absent at bases of basidia.

Originally described from the state of South Australia among thorn bushes.
