discussion |
Apparent morphological similarity to A.
levistriata and A.
sinapicolor suggest
to us that we should place both sp-57 and
sinapicolor in section Phalloideae.
Sporograph comparisons can be found on the techtab
of the taxon page for A. sinapicolor. With recent success in sequencing original material of A. levistriata, we have apparently found the closest (yet) North American relative of the present species. | ||||||||||||||||||||

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.
