BRIEF DESCRIPTION

This description is based on that of Beeli (1935) with additions from notes of recent collectors, etc.

The cap of A. bingensis is fleshy and firm and 40 – 75 mm wide; it is globose at first becoming expanded-convex, with a striate margin . It is pale yellow and covered with orange-red, pulverulent remnants of the volva. Its context is white..

The gills are subfree, attenuate at both ends, white edged with yellow or “yellowish apricot”, and 4± mm broad. Beeli provided no information on the short gills.

The stipe is 90 x 5 – 7 mm, yellow-orange and cylindric with a white bulbous base; its context is white and stuffed. The stipe is exannulate and decorated in the lower portion with orange-red remains of the pulverulent volva.

The taste is said to be sweet. The odor is not recorded.

The species was not known to be eaten by informants of David Arora.

The spores [from recently collected Zambian material] measure (7.3-) 7.5 – 9.8 (-11.0) x (4.5-) 5.1 – 6.5 (7.6) µm and are broadly ellipsoid to ellipsoid to elongate and inamyloid.

Amanita bingensis occurs scattered in dry tropical forest.
