I have no problem with your assignment in this case. However, what about the collection in Obs. 104261? KOH stains their stipes the same color and the mushrooms look very similar to this one, but with much more prominent reticulation.

occurs with wide variation in the stipe color, I think this probably carries over to the KOH reaction on the stipe. Maybe that’s why B/R/B does not mention a KOH reaction on the stipe.

I never said this was X. separans. X. separans is very easy to ID (fresh specimens of course) just by looking at it — it’s such a distinct looking bolete. I proposed genus Xanthoconium just because I was uncomfortable placing it in Boletus based on the overall appearance and KOH reaction.

KOH not right for X. seperans

On Mushroom Expert X. seperans page, Michael Kuo writes it stains greenish with KOH.
