These are listed under “sp-” on the index page for section Validae on the WAO website:

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,
