    • intro Amanita aureosolea is a species in the group with a pigmented, friable volva that darkens with agea nd exposure.  In the present, the original color of the volva is orange-yellow.
    cap The cap of A. sp-N29 is 46 - 79 mm wide, chestnut brown at first, later becoming sordid brown from the margin inward, unchanging when cut or bruised, planoconvex, and umbonate.  The cap flesh is white, sometimes with a brown area just under the cap's skin and is unchanging when cut or bruised.  The cap's margin is striate for 25% to 40% of the cap radius and nonappendiculate.  Volval remnants on the cap are present as small crumb-like warts or slightly larger warts or crust-like patches, easily removed, probably yellow originally, becoming brown to gray with orange-brown tint or dark brown, and finally gray brown to brownish gray with pale edges.
    gills The gills are free or receding, with or without connected lines on the top of the stem (10× lens), subcrowded to crowded, orangish cream to pale brownish white to dingy white in mass and cream to dingy cream to dingy white or watersoaked in side view.  The short gills are truncate, greatly varying in length, plentiful, and unevenly distributed
    stem The skirtless stem is 111 - 168 × 7.5 - 13 mm, pale brown to pale orangish-brown to pale orangish cream ground color, unchanging when cut or bruised, and decorated with orange-brown to brown fibrils.  The stem's flesh is white to off-white to pale tan, unchanging when cut or bruised, and hollow.  The volval remnants on the stem are in the form of a strangulate, fragile volva, ochraceous to bright yellow orange below stipe base and in one or two rings immediately above and/or below the strangulate (stretched-looking, undecorated) region, with the highest such ring 21 - 40 mm from the stem's base.  These rings often become orange-brown with time. Additional volva remnanats are occasionally found as gray warts and small patches above the uppermost ring.
    odor/taste The odor of this species is not noticeable in young material; older material was described to RET as having the odor of fried potatoes. The taste has not been recorded.
    spores The spores measure (8.2-) 9.2 - 12.0 (-13.5) × (7.5-) 8.8 - 11.0 (-12.5) µm and are globose to subglobose to broadly ellipsoid and inamyloid.  Clamps are probably absent from bases of basidia.
