This text is derived from the original
description of Amanita shennongjiana. The
fruiting bodies of Amanita shennongjiana are
small to medium-sized.
cap
The cap is 40 – 90 mm wide, plano-convex to
planar, raised over the stem (umbonate), grayish
brown to brownish. Volva is mostly absent,
but occasionally present as white patches. The
cap’s margin is radially grooved covering 40% - 50% of
the cap's radius. There is no material hanging
from the edge. The flesh is white.
gills
The gills are free, crowded,
and white. The short gills are truncate and plentiful.
stem
The stem is 100 – 160 × 5 – 12 mm, nearly cylindrical or
narrowing upwards, white to dirty white,and
covered with minute, concolorous
fibrils. The stem lacks a basal bulb. At
the stem's base, the volva is saccate,
15 – 30 × 10 – 15 mm, membranous, and is easily
broken into large patches during development
of fruiting bodies; both the inner
and outer surfaces are white.
odor/taste
The odor and taste were not recorded for the present species.
spores
The spores measure 10.0 – 12.0 × 9.0 – 11.0 µm
and are globose to subglobose and inamyloid. There
are no clamps at the bases of basidia.
discussion
Amanita shennongjiana is described from central
China (Hubei Province). It has associations with
broad-leaved trees.
The European
A. vaginata
can be confused
to A. shennongjiana in appearance, but
A. vaginata has a robust fruiting body, a
non-umbonate cap with relatively shorter
striations on the margin and a relatively
thicker volva on the stem’s base.&mdas;Yang-Yang

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.
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
material.
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 following material is derived directly from the
protolog of the present taxon and associated documen-
tation such as sequences deposited in GenBank.
