following is largely based on the original description (Wood 1997).
The cap of Amanita
pallidofumosa is up to 110 mm wide, pale smoky gray to pale gray
brown, convex then flattened convex, sometimes depressed at the center, smooth, dry,
thin-fleshed near the margin, with a striate margin. Some volval remains are
present that are white, membranous, flat, and irregular.
The gills are free to adnexed, crowded, thin,
white to off-white, with a white edge.
The stem is up to 125 × 13 mm, equal or
slightly narrowing upward, smooth and white above, off-white and finely hairy
ring is membranous and persistent, skirt-like, striate on the upper
surface, and white to
grayish. The base is only slightly clavate, with a saccate, prominent
volva, which is thick, membranous, and white.
The spores measure 10.5 - 12.0 (-13.2) × 7.2 - 9.6 (-10.2) µm and are broadly ellipsoid to ellipsoid and inamyloid. Clamps are absent at bases of basidia.
Wood describes the mushroom as occurring in
sclerophyll forests and "tall open forests" from the state of
New South Wales and Queensland, Australia. A sclerophyll forest in the Australian bush
is a forest of hard-leaved plants including Eucalyptus in the
This species is apparently unique in
being very similar to the species of Stirps Hemibapha, but (unlike all other
taxa in that Stirps) lacking clamps at the bases of basidia. This seems
so unusual that a revision of the type seems important.—R. E. Tulloss and L. Possiel

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
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 based entirely on the protolog of this species, which does not meet contemporary standards for Amanita taxonomy.
from protolog: [-/-/-] 10.5 - 12.0 (-13.2) × 7.2 - 9.6 (-10.2) μm, (Q = 1.27 - 1.52), inamyloid, broadly ellipsoid to ellipsoid.

from spore drawings in protolog: [2/1/1] 12.6 - 13.1 × 7.2 - 7.4 μm, (Q = 1.74 - 1.75).
from protolog: In tall, open forest.

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.
