white stipe on a flavoconioid amanita. There is a consistent spore size/shape associated with this color combination. The old Peck name A. elongata seems to apply.

Another thing to do would be to look at all the brown or brownish yellow or brownish orange entities to which I’ve given temporary codes.

distinct surface pigmentation.

Work needs to be done on the flavoconia group. The variety of colors and combinations of stipe and cap color are quite numerous. And we don’t know whether this variation is relevant to taxon delineation. We know that the rubescent taxa in the Americas have turned out to be much more diverse than was believed. And, in general, the diversity of section Validae is only just being approached in such areas as the rubescent taxa and the taxa similar to A. lavendula in the Americas.

Very best,

Rod
