The editors of this site owe a great debt to Dr. Cornelis Bas whose famous cigar box files of Amanita nomenclatural information gathered over three or more decades were made available to RET for computerization and make up the lion's share of the nomenclatural information presented on this site.
Peck + -iana, suffix indicating possession; hence, "of Peck"|

RET's old view that the subhymenium of this species
was not composed of inflated cells must be attributed
to his misinterpretation of the collapsed tissues of
the holotype, which he reviewed when he was
inexperienced. Modern collections of the species show
he was in error.|
RET's provisional name "A. canadensis" has been referred here because his idea that he was viewing a specimen distinct from A. peckiana was based in part on the above mentioned mistake.
This species has also been called "species 39" in old lists, keys, and correspondence of RET.

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.
