Macroscopically, this species resembles
originally described from
Trinidad and Tobago. Of the two, the present
species has distincly narrower spores.
The sporographs of these two species are compared in

"Santo Domingo Ringless Amanita"
Spore data for collections provisionally identified as: Amanita domingensis Angelini & Vizzini
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.
