Sorry. The variation was described by Smith under Boletus and them moved by Wolfe to the genus Xanthoconium. Index Fungorum lists them as conspecific.

Where does A.H. Smith come from? Shouldn’t the name remain with Peck and A.H. Smith for the variation?

(1833-1917) first described the species as Boletus affinis; Rolf Singer (1906-1994) later changed the genus to Xanthoconium, and changed the species name from affinis to affine to conform with Latin gender names.

Why are there two different authors for this binomial? Thanks for the ID!

there is reticulation on the stipe, but it is only on the stipe near the tubes.
