The cap of Amanita zangii is 50 - 60 mm wide, convex to applanate,
white, whitish to cream-coloured. It is covered with adnate, brownish grey, dark grey to blackish, small to
rather coarse, subconical (2 - 5 mm wide) to flat verrucose (5 - 10 mm wide), felty to subfibrillose volval
remnants. The cap's margin is smooth and appendiculate, and its flesh is white.
The lamellae are free, white, and crowded.
The stipe is 60 - 80 × 8 - 12 mm, subcylindric, annulate; and its surface is whitish to
cream-coloured. The bulb is subclavate to subglobose, 15 - 20 mm wide; and its upper part is covered with
inconspicuous, whitish to greyish, farinose to floccose,
volval remnants. The annulus is apical to subapical, white to whitish, and friable.
The basidiospores measure (7.5-) 8.5 - 11.5 (-12.0) × 6.5 - 8.0 (-9.0) µm, amyloid and
ellipsoid, rarely broadly ellipsoid or elongate, colourless, hyaline, and thin-walled.
Amanita zangii is known from tropical China.
It is very similar to A. hesleri Bas, originally described from the United
States, and was is assignable to Bas' stirps Hesleri. However, it differs from the latter by its smaller
basidiomes bearing shorter, relatively wider spores and with volval remnants on the pileus having smaller
inflated cells. Moreover, A. hesleri tends to have scale-like volval remnants towards the cap margin.

The following text may make multiple use of each data field.
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
The same field may also contain black text, which is data from a revision of the present
taxon (including non-type material and/or material not cited in the protolog).
Paragraphs of black text will be labeled if further subdivision of
this text is appropriate.
Olive text indicates a specimen that has not been
thoroughly examined (for example, for microscopic details) and marks other places in the text
where data is missing or uncertain.
The text below is derived entirely from the protolog of the present species.

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.
