I am not confident on this ID and would appreciate feedback. My best guess is Leccinellum albellum. But the reaction to FeSO4 suggests one of the Leccinums.

Found under oak. Several oaks, with no birch or conifers in range. 100%, definitely oak.

Brown caps (no red at all) are deeply fissured even in the younger specimens.

Long, stringy stems with scabers (though you have to look for them). Buff pores deeply depressed at the stem.

White flesh that does not stain on either old or new specimens, even after a long time.

White pores that age toward brown. Tubes are very deep.

No reaction to KOH on either cap skin or flesh.

FeSO4 had no reaction on the cap skin, but turned the flesh a light slate blue. This is consistent with the Leccinum group but not with the Leccinellum albellum, which should have had no reaction according to the texts.

No notable smells or tastes.
