BRIEF DESCRIPTION: Amanita roseitincta is a distinctive and unusual species. In the button stage, a triplex volva is present. The underlayer is pinkish rusty and pulverulent. The outer layer forms warts (at arrow in drawing on right) on a submembranous base (seen peeling off below the unexpanded cap in the top left photo). The color of the 30 - 70 mm wide pileus is off-white.  All pigments rapidly fade in sunlight.

The gills are free to subdistant, crowded, and pale cream to white. The free gills are truncate.

The stipe is 25 - 150 x 5 - 20 mm and has a skirt-like annulus that is pink at first (at least on the lower side) and an ellipsoid to somewhat turnip-shaped bulb.

My measurements from collections extending from New Jersey to Texas are as follows: (8.2-) 9.0 - 11.5 (-14.4) x (5.9-) 6.0 - 8.5 (-10.0) µm, broadly ellipsoid to ellipsoid, occasionally elongate.  Clamps are absent from the bases of basidia.

This species occurs from New Jersey (infrequently) to the U. S. Gulf Coast region. Dr. Jay Justice reports it occurs as far west as southern Missouri.  It, and/or a very similar species called A. guzmanii Cifuentes et al., occurs in eastern Mexico.

Amanita roseitincta is associated with oak and pine. -- R. E. Tulloss
