Technical description (t.b.d.)

BRIEF DESCRIPTION: The following is based on the description of Bas (1969).

The cap of Amanita ochrophylla is 90 - 170 mm wide, convex to plane or plano-concave, buff, often with pinkish, yellowish, or brownish tinges, slightly darker towards the center, dry, with a nonsulcate, appendiculate margin. The cap is covered with adnate, concolorous(?), rather thick, broadly conical to shapeless warts, flat scales, patches, or subfloccose crusts originating from the volva. A subfloccose covering appears to be present when the thin membranous outer layer of volva has been lost early in expansion. Flat scales and patches may have parts of this outer layer still in place.

The gills are crowded, free, rahter broad, whitish to cream at first, and later becoming ochraceous. The short gills are attenuate.

The stem is 110 - 190 x 15 - 30 mm, more or less equal, solid, pale buff to pale vinaceous brown, and usually without remnants of the volva. The base of the stem has a bulb (50 - 80 x 40 - 90 mm) that is clavate, broadly clavate, subglobose or subnapiform. The stem bears a superior annulus. Some illustrations show a thin patch or patches in circling the stem just above the stem's bulb or higher (even appearing to be a second, lower annulus). These appear to be remnants of the internal limb of the volva, according to Bas.

The spores measure 9.0 - 11.0 x (5.5-) 6.0 - 7.5 µm and are amyloid and ellipsoid to elongate. Clamps are distinct in young fruiting bodies at bases of basidia.

The present species was originally described from the state of Queensland, Australia and has also been reported from the states of New South Wales, South Australia, and Victoria (Reid, 1980).

Amanita ochrophylla is a member of Amanita subsection Gymnopodae Bas. Other taxa of that subsection will be listed on the A. gymnopus Corner & Bas page.
