This species is based on a single specimen from
Zambia. Molecular data has been obtained.
We are inquiring concerning more morphological data.
The umbonate cap of this species is yellow-brown and
bears quite short marginal striations.
The short gills of this species are truncate.
The slender stem of A. sp-Arora-01-555 bears a
narrow, membranous ring near the top. In the one
specimen that is known, a membranous patch of whitish
volva was found low on the stem.
Neither odor nor taste were recorded for this taxon.
The spores of this species measure (10.2-) 10.5 -
13.2 (-15.0) × (7.3-) 7.9 - 9.4 (-10.5) μm and are
broadly ellipsoid to ellipsoid and inamyloid.
Clamps are not found at the bases of basidia.
The present species is known only from a single
collection made in Zambia's Northern Province.
Amanita sp-Arora_01-555 somewhat near
A. madagascariensis based on the limited
genetic data available concerning the
latter. Both taxa belong in the small group
within section Vaginatae that have
rings on their stems.—R. E. Tulloss

Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer;
and explanations prepared for this site talk about specimen-observer pairs associated with each data set.
Combining more data into a single data set is non-optimal because it obscures observer differences
(which may be valuable for instructional purposes, for example) and may obscure instances in which
a single collection inadvertently contains a mixture of taxa.
