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. [Note: The nrLSU sequence for RET 075-3 has been deleted temporarily from the "GenBanks nos." data field, above.—ed.] | ||||||||||||||||||||||||||||||||

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. | ||||||||||||||||||||||||||||||||

Information to support the viewer in reading the content of "technical" tabs can be found here.
Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
