The fruiting bodies of Amanita sculpta are large to very large. The cap is 80 - 180 (-250) mm wide, convex to applanate, greyish brown, brownish to purplish brown, covered with brown to dark brown, conical volval remnants 2 - 10 mm high and 2 - 8 mm wide and becoming smaller towards the cap margin. The cap margin is smooth and appendiculate; the context is white to brownish, becoming brown to dark brown when injured.
The gills are free to subfree, white with pinkish tinge when young, purplish brown when mature, becoming black to dark brown when dried; lamellulae subtruncate to attenuate.
The stipe is 80 - 200 × 10 - 30 (-50) mm, subcylindrical or attenuate upwards, with a surface that is dirty white to brown, covered with brownish to brown floccose to farinose squamules, and a basal bulb 25 - 60 mm wide. The bulb is napiform to ventricose, with its upper part covered with brown, verrucose to farinose volval remnants. The annulus often breaks up and falls away.
The spores measure (7.5-) 8.0 - 11.0 (-15.5) × (7.5-) 8.0 - 10.5 (-14.5) µm and are globose to subglobose and amyloid. Clamps are not present at the bases of basidia.
This species was originally described from Singapore. It is found in southern China and also reported from Japan.
Due to delays in data processing at GenBank, some accession numbers may lead to dead 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
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 predominantly derived from Yang (1997); additional data is from the protolog and from Bas (1969); the remainder (marked "RET" is based on original research of R. E. Tulloss.

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.
