BRIEF DESCRIPTION: The fruiting bodies of Amanita ovalispora are small to medium-sized. Its cap is 40 - 70 mm wide, applanate, and sometimes slightly depressed in the center. It is gray to dark gray and glabrous and occasionally covered with white, membranous volval remnants. The margin is tuberculate-striate (30% to 40% of radius) and non-appendiculate, and the context is white.

The gills are free, white, becoming grey to brownish; and the short gills are truncate.

The exannulate stem is 60 - 100 x 6 - 15 mm, subcylindric or slightly attenuate upwards, fistulose, with a surface that is white to dirty white. The upper half of the stipe is often covered with white farinose squamules. The stipe lacks a basal bulb. At the stipe base, the volva is 20 - 40 x 12 - 25 mm, saccate, with an outer surface that is white to whitish and an inner surface that is white to greyish. There is an internal limb present on the inner surface of the volva.

Spores measure (8.0-) 9.0 - 11.0 (-12.0) x (6.5-) 7.0 - 9.0 (-9.5) µm and are broadly ellipsoid to ellipsoid and inamyloid. Clamps are absent from the bases of basidia.

Originally described from Indonesia, this species also is found in tropical China. -- Zhu L. Yang
