| 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 based on collectors' notes
and photographs, molecular research of S. D. Russell,
Dr. L. V. Kudzma and other original research of R. E.
Tulloss. |

| discussion |
At first, from above, this species seems to be a
specimen something akin to
Amanita rhacopus.
However, the present species has a weakly structured, white
partial veil.
This structure can, at least sometimes, break up so that
its lower part can fall away and slide down the stipe
until it catches on the stipe surface.
Having five collections from a single site, in the
present case, allows us to have a reasonable, initial
estimate for
the number and location of probable SNPs (single
nucleotide polymorphisms) in genes we can successfully
derive repeatedly. In this case we have five
copies of the nrLSU gene for this organism, all
beginning with the first character of the
5'-motif. The five initial segments of
are very similar in length—they range from 1443
to 1476 characters long.
The differences between the sequences that we
have observed and the positions at which the
differences occur are the following:
Each entry in this table provides a character
position in the aligned set of sequences and
the characters (including ambiguities)
recorded at that position. Character 1 is the
initial (leftmost) character of the 5' motif of
nrLSU. In the present case, the motif is that
characteristic of the provisional subsection
Penetratrices—TCTGACCTCAAATCA.
