name Amanita albosquamosa
name status nomen acceptum
author A. E. Wood
english name "White Blanket Lepidella"
intro The following is largely based on the original description (Wood 1997).

cap The cap of Amanita albosquamosa is up to 100 mm wide, convex then plano-convex or plane, smooth, dry, white to pale cream at the center, with a nonstriate and slightly appendiculate margin.  Small or large volval remains are present as white or pale cream patches and flat membranous scales, sometimes slightly thickened.
gills The gills are free, moderately crowded, thin, deep cream, with a white and serrate edge.  The short gills are present in at least two series.
stem

The stem is up to 100 × 10 mm, white, and powdery over the whole surface.  The ring is fragile, powdery, and never clearly present.  The base is bulbous to top-shaped, white.  Wood describes the volva as vague ridges on the upper part.  We think it is more likely that the powdery covering of the stem is remains of an internal limb of a volva than remains of a powdery "ring."

spores

The spores measure (8.7-) 9.0 - 11.1 (-12.0) × 6.9 - 8.4 (-9.0) µm and are broadly ellipsoid to ellipsoid and amyloid.  Clamps are uncommon at bases of basidia, when found they are quite distinct.

discussion

Wood describes the mushroom as occurring in sclerophyll forests and "tall open 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).

Given the evidence provided in the original description, this species is probably correctly placed in stirps Grossa. —R. E. Tulloss and L. Possiel
