Technical description (t.b.d.)

BRIEF DESCRIPTION: The description is largely based on the original description (Wood 1997).

The cap of Amanita ochraceobulbosa is up to 100 mm wide, convex then flattened-convex, smooth, dry, dull cream to cream-buff or yellowish-orange cream, with a nonstriate and appendiculate margin. Volval remains are abundant on the cap as pyramidal warts, often large, concolorous with the cap or more deeply tinted or deep buff, soft, sometimes flatter towards the cap margin. 

The gills are free, thin, crowded, white to cream, with a concolorous margin. The short gills are present in at least two series.

The stem is up to 110 × 15 mm, cream, with white granular covering overall. The ring is usually quick to disappear, but at first is present and fragile, white to cream, striate on the upper surface; it is rarely membranous or persistent. The bulb is markedly differentiated from the stem and subglobose to  top-shaped, off-white, sometimes having scattered conical warts on the upper part and sometimes with a "rim" on the upper part.  [Note: Wood's illustration of this species shows an entirely undecorated bulb.]

The spores measure 9.3 - 11.7 × (7.3-) 8.1 - 9.6 (-10.2) µm and are subglobose to broadly ellipsoid, (occasionally ellipsoid) and amyloid. Clamps are distinct but often scattered at bases of basidia.

Wood describes the mushroom as occurring in sclerophyll forests, "tall open forests,"  and Angophora forests from the state of New South Wales, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia).

Wood's placement of the current species in subsection Gymnopodae Bas seems inappropriate for a number of reasons: Absence of a submembranous outer volval layer, presence of warts on the bulb, pallid gill coloring, and no mention of staining flesh or distinctive odor. -- R.
