The cap of this species is 24 - 35 mm wide and gray with darker gray in the center. The cap's flesh is pale sordid white and 2 - 3 mm thick above the stem.
The caps margin is striate, with striations occupying about 55-80% of the cap's radius. Volval material is absent from the cap or appears as a single patch.
The gills are free, whitish or slightly sordid, and about 3.5 mm broad. The short gills are truncate and irregularly distributed.
The stem is about 40 × 2 - 2.5 mm, white, minutely striate lengthwise; and has no annulus. The volva on the stem's base is white on the outer surface,
sack-like, membranous, about 8 mm high, and connected to the stem just at the stem's base.
The spores measure (7.9-) 8.1 - 10.5 (-12.0) × (6.0-) 7.0 - 9.3
(-11.0) µm and are globose to subglobose to broadly ellipsoid (rarely ellipsoid) and inamyloid. Clamps are not to be found at bases of basidia.
This species is known from the Coastal Plain of Louisiana and the sandy forests of eastern Texas.—R. E. Tulloss

Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text

Information to support the viewer in reading the content of "technical" tabs
can be found here.
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.
