| 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.
Unless otherwise indicated, the text below is derived from
the description by Yves Lamoureux in his flicker account

| discussion |
Some comments of YL: In Québec, with the present species,
there sometimes also
occurs another amanita that is smaller with a pale ash-
gray to silver-gray pileus that is uniformly colored.
Unfortunately, we haven't had the opportunity to collect
the latter. In North America, both of these taxa
have been mistakenly identified as A.
vaginata.
