This text is derived from the original
description of Amanita orienticrocea. The
fruiting bodies of Amanita orienticrocea
are medium-sized to large.
cap
The fruiting bodies of Amanita orienticrocea
are medium-sized to large. The cap
is 50 – 110 mm wide, convex to plano-convex,
often raised over the stem (umbonate), brownish,
yellow-brown to yellow-gray in the center, gradually
changing towards the margin to dirty yellow,
cream to brownish. The cap’s margin is
radially grooved covering 20% - 30% 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, but
with gray tinge when young. The short gills
are truncate and plentiful.
stem
The stem is 70 – 150 × 7 – 15 mm, nearly cylindrical
or narrowing upwards, white to dirty white,
covered with indistinctly, white, dirty
white to brownish squamules. The stem lacks
a basal bulb. At the stem's base, the
volva is saccate, 30 – 50 × 15 – 30 mm,
membranous, outer surface is white,
inner surface is grayish.
odor/taste
The odor and taste were not recorded for the present species.
spores
The spores measure 9.0 – 11.0 × 9.0 – 11.0 µm
and are globose to subglobose and inamyloid. There
are no clamps at the bases of basidia.
discussion
Amanita orienticrocea corresponds to
A. cf. crocea; in Yang
(2015).
Amanita orienticrocea is described from
Yunnan Province, China. It occurs on
soil in pine, broad-leaved or mixed
forests with Breech (Fagaceae) and
Pine (Pinaceae) in southwestern China. Amanita
orienticrocea is similar to
A. crocea
(Quél.) Singer, but the latter has an obviously
saffron orange cap, white gills
lacking a gray tinge, and a stem
decorated with distinctly orange squamules.— 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.
