| intro |
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 photographs and
notes of
the collector, molecular work by L. V. Kudzma or
S. D. Russell, and other
original research of RET.

| discussion |
"Amanita sp-NFL06" is a
temporary code previously used for the present
taxon.
RET 686-3 is immature with very few sterigmate
basidia and only distorted or malformed giant
spores.
Given the samples in RET's herbarium, Dr. Ristich
applied the European name "A. umbrinolutea" to
both this taxon and
A. alligator. |
