name Amanita manginiana
name status insufficiently known
author Har. & Pat.
english name "Mangin's False Death Cap"
intro The following description is based on Gilbert (1941).
cap The cap of Amanita manginiana is 50 - 80 mm wide, chestnut brown, darker in the center, with the margin more pallid, silky (bearing fine hairs), convex then applanate, fleshy, and has a nonstriate margin.
gills The gills are adnate and white. Short gills are present.
stem The stem is 50 - 80 mm high, cylindric, stuffed, white, becoming orangish-brown. The bulb is fleshy, globose to ovoid. The ring is membranous, white, superior, skirt-like. The volva is membranous, limbate, and fulvous-white.
spores The spores measure 7 - 8 × 6 µm and are ovoid to subglobose. Gilbert's (1941) drawings of spores sometimes do not match the information provided in his descriptions. In this case, measuring the spore drawings show length varying from 9.2 - 10.3 µm and in the case for the only two spores shown in side view, the width is 7.5 - 7.8 µm. Basidia probably lacking clamps because of its assigned section.
discussion

Originally described from Vietnam.

This species is very poorly known. The material of the type was preserved in liquid but even in Gilbert's time, the spores were in very bad condition. At present, the type has been allowed to dry out. The spore are nothing but amyloid rubble and the specimens are, unfortunately, almost entirely useless. Yang reports a species similar to A. manginiana from China under the name A. manginiana sensu W.F. Chiu. A. manginiana appears to belong with a group of edible species that at the moment are classed in section Phalloideae. The reader may also want to see the description of A. pseudoporphyria Hongo.—R.
