Amanita striatuloides

The following is largely based on the original description (Wood 1997).

The cap of Amanita striatuloides is up to 40 mm wide, convex then plane or slightly depressed, smooth, dry, dull cream to yellowish cream, paler in the outer portions, with a strongly striate margin. The volval remains on the cap are flat, fairly thin, membranous patches, white to yellowish cream.

Gills are free, thin, crowded, white to pale pinkish.

The stem is up to 60 × 7 mm, off-white to pale cream, smooth, with a slightly clavate base. The base is white to off-white, with a ring of volval remnants (sometimes scaly) on the upper portion of the clavate base. No ring is present.

The spores measure 8.7 - 10.2 × 7.5 - 9.3 µm and are globose to subglobose and inamyloid.  Clamps are absent at bases of basidia.

Wood based his description on two specimens from sclerophyll forests in the state of Queensland, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia).

Wood suggests A. striatuloides is similar to his A. crematelloides A. E. Wood; however, the latter species has a pulverulent universal veil.—R. E. Tulloss and L. Possiel
