And so I ask

what if anything is xerocomoid about this mushroom (hortonii)and since this mushroom (hortonii) is almost identical to Boletus subglabripes in every way except for the wrinkled cap what does that say about what molecular studies contribute to the useful generic reassignment of individual mushrooms? If subglabripes and hortonii belong in seperate genera we must assume that the authors believe that the nearly identical appearence of these two taxa MUST be the result of convergent evolution. Does anybody here have another explanation?

in the Binder & Besl paper

they rename B. hortonii Xerocomus hortonii

i agree this is L. subglabripes

and this mushroom is not all that common here in CT but the close look-a-like, Boletus hortonii is fairly common and is identical in every macro feature EXCEPT the wrinkled cap. So is Boletus hortonii a Leccinum? Peck described it (hortonii) as Boletus subglabripes var. corrugis and Smith elevated to species status as B. hortonii but is this one Singer wasn’t familar with? because to me if you’re calling subglabripes a Leccinum you have to call hortonii a Leccinum too.
