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 revision (4 October 2021), the closest nrITS sequence of section Vaginatae in GenBank was was nearly 7% distant (by pairwise comparison of trimmed nrITS) from A. sp‑T48. | ||||||||||||||||||||

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.
