Aureoboletus innixus may be

a good possibility Igor.
An isolated fruit body in a semi-foreign land may not have all the classic features.
Unfortunately I didn’t spend a lot of time on it(before drying) so I can’t answer your questions.
Thanks for the input.

Interesting find, Ron

The color scheme reminds me of Aureoboletus innixus, but the shape of the stipe suggest otherwise. The spore size is a good fit with A. innixus as well. Were the tubes “xerocomoid”, i.e. splitting in half when pulled away from each other? What about macrochemical tests?
