| discussion |
Unfortunately, at the present time, this species is represented by a collection that appears to be too young to represent the normal range of spore shape and size variation (specimens in the collection bear "giant" spores) and by a collection comprising a single, overmature fruiting body having spores with distribution of both length and Q clearly truncated—lacking data from the probable upper portion of the range of these variables. The present species is distinguished from A. jacksonii by the bicolored pileus, the proportionately narrower spores, and the form of the partially opened cap (with decurved margin). A sporograph comparison of the present species with A. jacksonii is provided below: A sporograph comparison with the somewhat similar A. sp-F11 demonstrates that that species, so far as is known, has proportionately narrower spores than the present one: It is my impression that there is more yellow on the pileus margin in this entity than in Amanita sp-AR01, and the disc of the latter is reportedly a brownish red; a comparison of the sporographs of the two taxa is found below. The sporograph of the present species is similar to that of Amanita sp-Hesler-22051 for which little information is available. ??more?? | ||||||||||||||||

Spore data sets and their composite
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.
