discussion
In the field, this species can be segregated from
A.
anthracina because the pileus of the latter is
entirely black. In addition, the two species are
genetically distinct.
At the date of this writing (12 March 2017), the
closest sequenced species of section Vaginatae
was well over 5% distant (by pairwise comparison of
nrITS) from A. sp-T48.

Spore data for collections provisionally identified as: Amanita sp-T48 Tulloss, Kudzma & D. P. Lewis
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.
