  • 1. Amanita sp-AR01, N of Crossville, Cumberland County, Tennessee, U.S.A.   (RET 507-10).



  • 2. Amanita sp-AR01, N of Crossville, Cumberland County, Tennessee, U.S.A.   (RET 507-10).

    • intro This species was recognized as distinct based on collections cited on the technical tab with strong support from molecular work by Santiago Sanchez-Ramírez.
    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
