Fruiting bodies of
Amanita subglobosa are medium-sized to large, or
The cap is 40 - 100 (-150) mm wide,
convex to applanate, sometimes concave, brownish to brown
to cinnamon-buff, darker in the center, densely covered
with white, dirty white to yellowish, conical to
verrucose volval remnants 1 - 2 mm high and 1 - 2.5 mm
wide; the cap's margin is striate (10% to 40% of radius)
and non-appendiculate; the cap's context is white.
The gills are free to
subfree and white to cream; the short gills are truncate.
The stipe is 50 - 150
(-240) × 5 - 20 (-30) mm, subcylindric, cream to white,
and fibrillose; the stipe's basal bulb is 15 - 35 mm wide
and subglobose, with its upper part covered with white,
or sometimes yellowish to brownish, verrucose, granular
to farinose volval remnants. There is often a collar
encircling the base of the stipe and atop the bulb. The
annulus is membranous, white, often on the upper part of
stipe, although sometimes almost median, and persistent.
The spores measure
(7.5-) 8.5 - 12.0 (-15.0) × (6.0-) 7.0 - 9.5 (-12.5) µm
and are broadly ellipsoid to ellipsoid (or rarely
subglobose or elongate) and inamyloid. Clamps are common
on the bases of basidia.
from southwestern China and widely distributed in that
country, this species may occur in Japan also.

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.
NOTE: Spore data from papers by Z. L. Yang are presented following his use of the "Times New Roman" face for "Q" and "Q'"—respectively, "Q" and "Q."

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.
