BRIEF DESCRIPTION: The following description is based on Jenkins (1977), notes found with holotype, and data on recent collections.

The cap of Amanita pantherina var. pantherinoides is 30 - 100 mm wide, globose to hemispherical, becoming planar, honey-colored to dirty-cream colored with brown to chestnut to honey-tan in the center, viscid when wet, glabrous, with a faintly striate to nonstriate margin.  The volval remnants are present as soft, small, white, floccose-fibrillose patches and warts, numerous and randomly distributed until falling away.  The flesh is thin.

Gills are white, narrowly adnexed to free, when free, connected to the stem by an extremely heavy, floccose line, crowded; the short gills are truncate.

Its stem is 20 - 110 x 5 - 11 mm, tapering upward, often slightly expanded at the top, white to whitish, and stuffed to hollow, glabrous.  The basal bulb is ovoid, white, smooth to minutely floccose.  The ring is relatively large, white, superior, not apical, and persistent.  The volva is present as a submembranous, short, thin limb around the stem base and/or as floccose material an the upper part of the bulb.

I have measured spores from three collections of this species including Murrill's type.  The spores measure (8.1-) 8.5 - 11.2 (-12.2) × (6.0-) 6.3 - 7.7 (-8.5) µm and are mostly ellipsoid (with about 5% elongate and 5% broadly ellipsoid) and are inamyloid.  Clamps are rarely present at bases of basidia.

Originally described from the state of Washington, USA under the two names cited at the top of the page.  The synonymy was proposed by Jenkins (1977).  This species was originally found under conifers and hardwoods in wet, coastal forests.
