intro

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.

pileus

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.

peridium

lamellae

stipe

100^± - 205 × 10 - 60[??] mm, light peach colored; partial veil present; universal veil saccate, white.

odor/taste

ecology

Subgregarious. At 393 m elev. In open oak-cedar (Quercus-Juniperus) woods.

material examined

U.S.A.: ARKANSAS—Washington Co. - Farmington [36.0354° N/ 94.2268° W, 393 m], 28.vi.2004 Larry McGarrah s.n. [Tulloss 6-28-04-A] (RET 373-9).

name	Amanita sp-AR01
name status	cryptonomen temporarium
author	Tulloss
cap	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.
gills	There is no recorded information about the gills of this mushroom.
stem	The stem is approximately 100 - 205 × 10 - 60[?] mm and. light peach colored. The stem has a ring and white, sack-like volva.
odor/taste	Information about odor and taste of this mushroom have not been recorded.
spores	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.
discussion	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
