The editors of this site owe a great debt to Dr. Cornelis Bas
whose famous cigar box files of Amanita nomenclatural information
gathered over three or more decades were made available to RET for computerization
and make up the lion's share of the nomenclatural information presented on this site.

| 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.
The following material is derived from the protolog
of the present species and the type study of
Bas (1969).
Bas (1969):
Basidiomes medium-sized,
slender. |
| pileus |
protolog: 80 mm wide, yellow,
plano-convex; context white, thin;
margin not described; universal veil as
covering of orange farinaceous squamules, easily
removed.
Bas (1969):
up to 80 mm wide, golden
yellow, plano-convex; context rather thin,
white; margin nonstriate, appendiculate;
universal
veil as orange-yellow pulverulent-floccose to
squamulose covering, detersile. |
| lamellae |
protolog: free, not remote,
white.
Bas (1969):
free, rather crowded, white,
narrow to
moderately broad, with entire edge; lamellulae
attenuate. |
| stipe |
protolog: 140 × 12.5 mm,
narrowing upward, 7 mm wide at apex, 18 mm wide at
base, with base rounded, decorated by universal veil
(see below); context white; partial
veil "membranous, friable," orange, to 20% of
pileus (width?); universal veil decorating
stipe from partial veil to several cm above
base.
Bas (1969):
up to 140 × 7 - 18 mm,
pale yellow (visible at top and at base),
narrowing upward; bulb absent or slight;
context hollow, white; partial veil
apical, pendent, submembranous-subpulverulent,
orange-tinged; universal veil as
orange-yellow
floccose scales over most of stipe. |
| odor/taste |
neither recorded. |
macrochemical
tests |
none described. |
| pileipellis |
Bas (1969):
difficult to delimit from pileus
context and universal veil remnants, not gelatinized,
as rather thick yellowish-brownish layer; filamentous
hyphae 4 - 10 (-15) μm wide, repent
interwoven, with some slightly encrusted. |
| pileus context |
not described. |
| lamella trama |
Bas (1969):
bilateral, divergent, with
divergent elements up to 30 μm wide, inflated
terminal cells probably lacking. |
| subhymenium |
Bas (1969):
cellular. |
| basidia |
Bas (1969):
35 - 40 × 7 - 8 μm,
4-sterigmata; clamps not observed. |
| universal veil |
Bas (1969):
On pileus: inflated cells
yellowish-brown, subcylindric to elongate-fusiform to
slenderly clavate, up to 210 × 40 μm, in
loosely arranged, interwoven, periclinally to
anticlinally oriented chains.
On stipe: similar to material on pileus, but
with elements usually smaller; filamentous hyphae
3 - 10 μm wide. |
| stipe context |
Bas (1969):
longitudinally acrophysalidic;
filamentous hyphae 3 - 10 μm wide;
acrophysalides up to 400 × 40 μm,
terminal singly or in chains. |
| partial veil |
not described. |
| lamella edge tissue |
Bas (1969):
not found. |
| basidiospores |
protolog: 7 - 8 μm in diameter, globose, hyaline.
Bas (1969): [20/1/1] (6.0-) 7.0 - 8.5 (-9.0) × (6.0-) 6.5 - 8.5 μm, (Q = 1.0 - 1.10), colorless, hyaline, with slightly thickened walls, amyloid, globose to sublgobose, slightly attenuating toward apiculus; apiculus rather strongly projecting; contents guttulate; white in deposit. |
| ecology |
protolog: In groups.
Under brush in dry forest.
Bas (1969):
Gregarious. In dry
forest. |

| discussion |
Bas (1969):
"The fruit-bodies of
Goossens-Fontana 280 were collected on at least two
different dates. As Beeli
(1927)
mentioned April 1923 as the collection date in the
protologue, the part of Goossens-Fontana 280
collected on that date is selected as
lectotype. The rest of the specimens of
Goossens-Fontana 280, the collection date of which
is uncertain, represents one or more syntypes,
cited indirectly in the original description, viz.
by the number 280. However that may be, all
specimens of Goossens-Fontana 280 appear to be
conspecific.
"Amanita aureofloccosa from Central Africa is
the only species in section Lepidella with
really bright colours. Yet the type of spore,
the type volva, and the slender, early hollow stem
demonstrate such a close affinity to
A. thiersii
that it must be placed in the same stirps as that
species."
Wartchow et al.
(2015)
report this species from
semideciduous, seasonal forest in the state of Rio
Grande do Sul, Brazil. |
