The following text may make multiple use of each entry 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.

Catcheside PSC 1813 (AD).
The spore shape range of A. sp-AUS18 is
within the range of the
spore shapes of known taxa of Amanita stirps
However, the spore size range is on the small side
for Australian species in the cited group. The
size range is closest to that of
murinoflammeum. However, the latter
species has a
rather strongly saturated red-brown cap, a grayish
partial veil and a grayish lower stipe.
Although the sample is limited,
murinoflammeum appears to
be segregated further by its nrLSU sequence.
Pileus coloration and nrLSU sequence also serve to
segregate the present species from Amanita
albertellarum, which has been found growing
at the Little Hartley site from which RET 474-7 was
bambra both appear to be based on mixtures
of taxa. It is worth while noting the ranges
of cap color, gill color,
spore size, and form of the universal veil in the
Gilbert's illustration (Gilbert 1941 Tab. 23) of A. umbrinella
clearly includes a dark capped species that fits
with the the fact that some collections of
umbrinella were originally labeled as A.

calyptra and a robust volval sac at the base of what
appears to be a totally elongating stem. It's

pinkish gills. Hence, it is plausible that the
roseolamellata or something very like
it—was included in the original
concept of umbrinella by the
Since roseolamellata grows at the Little
Hartley site also, it seems plausible that
sp-AUS18, albertellarum, and
roseolamellata could all have been collected
together during a period of absence of relevant
Since none of the mentioned organisms match the very
dark cap generally associated with A. umbrinella
I assume that it is distinct from the species mentioned
Once again sequencing of Wood's Amanita types seems
a very important thing to do.
The nrLSU derived from RET 474-7 is identical (in
the ares of overlap) to
a sequence reported by (Wolfe et al. 2012) as
"umbrinella. It seems that the organism
name associated with genes extracted from Wolfe's
material from South Australia should be changed.
