I find that flavoconia and flavovirens…

seem to intersect, in terms of several different macroscopic traits. With my own collections, I tend to trust the presence/absence of reddish-brown staining in the stipe base. But I do wonder, what is the earliest stage of development for which flavorubens shows staining?

By “complex entity” with regard to flavorubens

I meant genetically complex. For example, it seems that the species as currently understood could be another case of potential hybridization or other scrambling of the “proposed fungal barcode” gene.

Very best,

… I get the impression that I am looking at several different species. I do think
that we should restrain the use of flavorubens…applying the name only when the stem base is clearly stained/staining. Amanita flavorubens, itself, appears to be a complex entity. We also know that there are many yellow and orange Validae that are undescribed (from careful anatomical or molecular examination). There is a lot of work to be done…and the issue is worldwide…not restricted to North America.

Very best,
