| Amanita ingwa
Grgur. "Grgurinovic's Dark Amanita"
Technical Description. (t.b.d.) BRIEF DESCRIPTION: The following is based on the original description by C. A. Grgurinovic (1997). The cap of Amanita ingwa is up to 60 mm wide, convex when young, becoming almost plane with age, with an entire margin. [Note: Oddly, the color of the cap is not given in the original description. From the name an aboriginal word for "dark," one would assume the cap is dark brown at first.] As it expands, the cap can become virgate. The surface of the cap appears velvety over most of the cap at first because it is covered by the volva. The volva may be somewhat warty in the center; The volva is yellowish at first, becoming browner towards the center; some of it may persist as warts in later development. The gills are almost free, crowded, and white. The short gills are present in one of two series. The stem is up to 80 x 18 mm (width measured at apex), white, becoming slightly brownish towards the bulbous base (up to 30 mm wide). The spores measure 8.4 - 12.0 x 5.7 - 7.9 µm and are ellipsoid to broadly ellipsoid and amyloid. Clamps are absent at bases of basidia. Amanita ingwa was originally described from the state of South Australia. No associated plants were mentioned. This species is a bit unusual for Amanita sect. Validae because the limited drawing of the subhymenium in the original description comprises uninflated cells. I cannot recall another species of that section with this character. Perhaps, the drawing doesn't fully represent the mature subhymenium or represents a subhymenium of a specimen too old or poorly preserved to be rehydrated. -- R. E.
