  • 1. Amanita wadjukiorum, Western Australia, Australia.

    • intro Amanita wadjukiorum is another of the stiking species of subsection Soliariae recently described from the state of Western Australia.  The following information is entirely derived from the original description of the species.
    cap The 50 - 105 mm wide cap of A. wadjukiorum is up to 10 mm thick and initially cream to clay buff becoming milky coffee to hazel to drab to snuff brown with age (occasionally paler at its edge).  At first it is convex; it becomes flattened with a central depression.  It is slightly tacky when moist.  The cap's flesh is white to cream and becomes vinaceous-buff to fawn above the stem.  The edge of the cap smooth and appendiculate. Volva remains on the cap are somewhat fluffy and may be widespread or restricted to the cap's center.  The volva initially forms a crust that breaks into low, conic warts or patches that become firmly attached to the cap.  At first, the volva is white or pale smoke-gray or pale vinaceous-buff or clay-buff; with age it becomes hazel or drab.
    gills The 4 - 12 mm wide gills are narrowly attached or free, close to subcrowded, and an unchanging shade of cream.  The short gills are truncate to subattenuate, plentiful, and vary in length.
    stem The stem of A. wadjukiorum is cylindric or narrows upward and measures 30 - 72 × 8 - 20 mm.  It is white initially and becomes pale smoke-gray to vinaceous buff. A ring is present at or near the top of stem; it is soft, striate on the upper surface, white to cream to vinaceous-buff, and often disappears with age.  Below the ring, the stem is densely covered with white fibrils and fluffy scales that turn gray to clay-buff to sienna with age.  The solid flesh is white to cream in at least the upper part of the stem and sometimes vinaceous-buff to smoke-gray to mouse-gray in the stem's base.  The stem's bulb is 10 – 35 × 25 – 55 mm and is turnip- to top-shaped at first, then spindle-shaped. The volva is often not apparent; it may appear as small soft warts or a small free limb on the bulb; it is white at first and ages to pale buff.  The volva is easily separated from the mushroom during collecting and often is left in the soil.
    odor/taste The odor of this species is described as "none to strong."  The taste is not recorded.
    spores The spores of this species measure (8.0–) 9.0–12.0 (–14.0) × (5.5–)6.0–7.0(–8.0) μm and are ellipsoid to elongate and amyloid.  The spore walls are slightly thickended.  Clamps are rare at bases of basidia.
