Based on the original
description of Murrill (1941)
and a type study by Jenkins (1979).
The cap of A. subrecutita is 50 - 70 mm wide, surface tan,
viscid, with scattered patches of volva, with a striate margin. The flesh is thin and white.
The gills are narrowly adnate, crowded, and white.
The stem is up to 60 × 6 - 8 mm, stuffed to hollow, cylindric, white, with a membranous, shallow cup as the volval
remnants. Although unmentioned by Murrill, Jenkins reports an ellipsoid basal bulb. Murrill's description of the volva suggests a
species of section Caesareae. Jenkins suggests a volval limb as might occur in A. gemmata (Fr.) Bertillon
in Dechambre of sect. Amanita. The ring is placed about the middle of the stem, and is small, white and
The odor is absent. The taste is mild.
The spores measure 12.5 - 13.3 × 7.0 - 8.6 µm and are ellipsoid to elongate and inamyloid.
Clamps are absent at bases of basidia.
Originally described from Florida, USA at the edge of a pond. Murrill uses the word "flatwoods" as the description of the
Jenkins' description of the type would place it within sect. Amanita, possibly near A. gemmata or
A. patherina (DC. : Fr.) Krombh. Since the margin of the cap is not striate and Jenkins
detected a distinct bulb in the type material, it seems best to follow Jenkins' classification. The species (so far as I know) is known only
from the type collection. Perhaps the most similar taxa might be Amanita eliae Quél.

The following text may make multiple use of each data field.
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
The same field may also contain black text, which is data from a revision of the present
taxon (including non-type material and/or material not cited in the protolog).
Paragraphs of black text will be labeled if further subdivision of
this text is appropriate.
Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text
where data is missing or uncertain.

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer;
and explanations prepared for this site talk about specimen-observer pairs associated with each data set.
Combining more data into a single data set is non-optimal because it obscures observer differences
(which may be valuable for instructional purposes, for example) and may obscure instances in which
a single collection inadvertently contains a mixture of taxa.
