for one exemplar is all the justification that exists for placement of B. hortonii in Xerocomus. That’s pretty thin evidence, I think..

This is a revert to an accepted name. The person who deprecated this name has not presented a case for deprecation.

Hi Alan,

I skimmed the Binder & Besl (2000) article you linked, and noted that they used the neighbor joining method for their phylogenetic analysis, and that their phylogenetic tree is based on one gene.

I wonder what we would see with better phylogenetic methods and analysis of many genes.

Frankly, I think the science presented in this 15 year old paper does not warrant the deprecation of this taxon name. You would have to at least present an argument to convince me. A naked link to an old paper is not sufficient.
