| 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 the collector's
comments, molecular research of Steve Russell, and other original research by R. E.
Tulloss. |

| discussion |
At first glance, RET 706-5 appeared to be assignable
to A. penetratrix;
however, the umbo of the present
species is distinctly tan rather than brown; and the
remainder of the cap is a solid pale gray at first
and not virgate.
Also, sequencing of RET 706-5 revealed that
the 5' motif of the nrLSU sequence was the typical
one for sect. Vaginatae and not the less
common TCTGACCTCAAATCA,
which is found in A. penetratrix,
A. penetrans, A. chiricahuana,
and a number pf other species. For a current
list of
the latter group of taxa see the techtab of A.
penetratrix (link above).
According to BLAST runs, the present species clusters
most closely with a number of
North American species, provisional species, and
temporary codes presently
assigned to Amanita
stirps Fulva: A.
carolinensis, A. fuligineodisca, and A.
fulva. |
