This species was recognized as distinct based on
collections cited on the technical tab with strong
support from molecular work by Santiago
The cap is 90± - 220 mm wide, bright scarlet to dark rust red, fading with age to a canteloupe color (rather pale orange) and lighter at margin, and viscid when moist The cap's margin is striate, and volval remnants are absent from the cap.
There is no recorded information about the gills of this mushroom.
The stem is approximately 100 - 205 × 10 - 60[?] mm and. light peach colored. The stem has a ring and white, sack-like volva.
Information about odor and taste of this mushroom have not been recorded.
The spores measure (8.0-) 8.6 - 11.0 (-19.2) × (5.7-) 6.0 - 7.4 (-8.0) µm and are ellipsoid to elongate (rarely cylindric) and inamyloid. Clamps should be present at bases of basidia; however, detailed microscopic studies have not yet been carried out.
At the moment, this taxon is only known from oak-"cedar" (Quercus-Juniperus) woods in Arkansas, U.S.A.
As the reader will see (above) more data is needed about all the macroscopic characteristics of this mushroom. This means that more well-collected, well-dried, well-annotated, and well-photographed collections are needed.
Larry McGarrah, the collector of the first material RET received of this taxon, reports that the species is eaten by squirrels.—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
where data is missing or uncertain.
The following material is based upon original research by R. E. Tulloss.
90± - 220 mm wide, bright scarlet to dark rust red, fading with age to a canteloupe color (rather pale orange) and lighter at margin, viscid when moist; context ??; margin striate; universal veil absent.
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.
