  • 1. Amanita grallipes

    • intro The following is derived from the original description of Amanita grallipes.
    cap The cap of A. grallipes is 22 - 90 mm wide, from hemispherical or conico-convex to plano-convex or flat without an umbo, dry, fleshy, having an appendiculate margin when young.  The cap is uniformly dark brown to somewhat paler grayish brown. The volva is present as scattered, concolorous, adnate, pyramidal warts.  The flesh is white.
    gills The gills are free, very crowded, fairly broad (up to 11 mm), at first pure white, then cream, and finally yellow to golden yellow.  The short gills are attenuate.
    stem The stem is 70 - 120 × 10 -18 mm (width measured at broadest point, just above the soil), solid, white, at first annulate, then exannulate, and dry.  The stem tapers downward and is rooting.  The volva comprises small, erect to appressed, pale yellowish brown, floccose scales.  The annulus is rather thick, white and smooth on both surfaces, felted-membranous, and fugacious; and it bears brown warts on its margin.  The flesh is white, but may bruise slightly yellow in the base of the stipe.
    odor/taste The fruiting body lacks an odor and tastes "mild."
    spores The spores measure 7.5 - 9.6 × 5.6 - 6.9 (-7.2) µm and are amyloid and broadly ellipsoid to ellipsoid.  Clamps are distinct at bases of basidia.
    discussion Amanita grallipes was first described from southern Brazil and is known only from that region.

    This species was placed by its authors in Amanita subsect. Vittadiniae Bas and Bas' stirps Vittadinii.—R. E. Tulloss
