intro The following is based on the original description of Murrill (1944), with the addition of my observations of the type.  RET would like to make it clear at the outset that this species is very difficult to separate from A. elliptosperma.  The possibility of synonymy is very real.
cap The cap of Amanita pseudoverna is 40 - 60 mm wide, convex to expanded, smooth, glabrous, rarely with volval patches, with an entire even margin. The cap is sometimes white, the center is sometimes cream.
gills The gills are adnexed, inserted, close, narrow, entire, brown when dry.
stem The stem is 80 - 120 × 10 - 15 mm, tapering upward, floccose, at times very rough. The bulb is large, ovoid, not radicate, about 40 × 30 - 40 mm. The volval limb is free, lobed or lacerate. The ring is very large, fixed 10 mm from the top of the stem, and persistent.
odor/taste Odorless.  As a precautionary measure, this species should be considered deadly POISONOUS.
spores The spores of the type measure 9.0 - 10.8 (-12.0) × 6.2 - 8.0 (-8.2) µm and are ellipsoid, occasionally broadly ellipsoid, rarely subglobose and amyloid. Clamps are absent at bases of basidia.
discussion

This species was originally described from Florida where it was collected under oak.

This is one of the taxa that is extremely close to Amanita elliptosperma G. F. Atk. and the name of which could well be placed in synonymy with the name of the latter. See the discussion of A. elliptosperma in the key to species of sect. Phalloideae in Central and North America.—R. E. Tulloss
