This text is derived from the original
description of Amanita squarrosipes.
The fruiting bodies of Amanita squarrosipes are
medium-sized.
cap
The cap is 65 mm wide,
convex to planar, grayish to
brownish gray. The cap’s margin is
radially grooved for about 20% to 30% of the radius
and lacks material hanging from its edge.
The flesh is white.
gills
The gills are free, crowded, and white to
cream. The short gills are truncate and plentiful.
stem
The stem is 190 × 13 mm, nearly cylindric
or narrows upwards, white to grayish, and
covered with gray to dark gray squamules
under the ring. The stem lacks a basal bulb.
The volva is
saccate, 50 × 25 mm, membranous, and has
white to dirty white inner and outer surfaces.
The ring hangs from a region 30 mm below
the stem's top, the upper surface is grayish
and the lower surface is gray brownish.
odor/taste
The odor and taste were not recorded for the present species.
spores
The spores measure 9.0 – 11.0 × 8.5 – 10.5 µm
and are globose to subglobose and inamyloid.
Clamps are common at bases of basidia.
discussion
Amanita squarrosipes occurs in subalpine forests
with Spruce (Picea), Oak (Quercus) and
Rhododendron.
Amanita squarrosipes corresponds to
Amanita cf. imazekii in Yang
(2015).
Morphologically, A. squarrosipes can
be confused with
A. imazekii
Oda et al.
However, A. imazekii has a relatively
larger fruiting body, and a white stem
densely covered with white to grayish squamules.—

intro
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.
