This text is derived from the original description
of Amanita tenuifulva. The fruiting bodies of
Amanita tenuifulva are medium-sized.
cap
The cap is 50 – 80 mm wide, plano-convex to
planar, raised over the stem (umbonate), dark brown
in the center, gradually changing towards the
margin to brown to brownish. The cap’s
margin is radially grooved for 50% of the
radius. There is no material hanging from the
edge. The flesh is white to cream.
gills
The gills are free, crowded, and white
to cream. The short gills are truncate and plentiful.
stem
The stem is 100 – 140 × 9 – 15 mm,
nearly cylindrical or narrowing upwards, dirty
white to brownish, covered with white
to brown tomentum. The stem lacks a
basal bulb. At the stem's base, the
volva is saccate, 16 – 35 × 13 – 20 mm,
membranous, and both the inner and outer
surfaces are white with brown tinge.

odor/taste
The odor and taste of the present species were not recorded.
spores
The spores measure 10.0 – 12.0 × 10.0 – 11.5 µm
and are globose to subglobose and inamyloid. There
are no clamps at the bases of basidia.
discussion
Amanita tenuifulva is described from Yunnan
Province, China. This species occurs in broad-leaved
forests with Fagaceae.
Amanita tenuifulva is similar to
A. fulva
Fr., but
the latter differs from the former in its
relatively robust fruiting body with a
proportionally shorter stem, and the structure
of the volval remnants on the stem’s base. In
China, A. tenuifulva is also comparable
to
A. orientifulva
Zhu L. Yang et al. However,
A. orientifulva has a relatively robuster
fruiting body, larger spores
(Q = 1.0 - 1.12 (-1.23) and scarce inflated
cells in the outer part of the volval
remnants on the stem’s base.—Yang-Yang Cui

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.
