Technical Description. (t.b.d.)

BRIEF DESCRIPTION: Description based on Reid (1980).

The cap of Amanita rosea is up to 66 mm wide, becoming flattened, slightly depressed at the center, cream-colored, pale pink toward the smooth margin with scattered darker pink blotches.

The gills are cream-colored.

The stem is up to 85 x 13 mm, white, minutely dotted with yellow in the lower half, with pink nearer the top. There is no annulus on the stem, and the volva is present as a white, thin membranous limb at the top of the basal bulb.

Reid reported that the spores of this species measure (9.5-) 10.2 - 14.0 (-15) x (5.5-) 6.0 - 6.6 (-7.75) µm and are ellipsoid to elongate to cylindric and amyloid. Clamps are absent at base of basidia.  My measurements of spores from the type in Kew are (9.5-) 11.2 - 15.8 x 6.1 - 8.5 µm.

Originally described from state of Victoria, Australia. It's ecology is not recorded.  A comparison between the description of A. mutabilis Beardslee (Bas 1969) and the present species shows many points of similarity. I am inclined to believe they should be placed together in Bas' stirps Preissii (see A. preissii (Fr.) Sacc.).  -- R. E. Tulloss
