Mixed woods. White Ash, Oak, Striped Maple, Shagbark Hickory, and some White Pine. These were closest to Ash and Hickory. Don’t remember tasting it, but this area has an abundance of bitter tylopilus species.

Of the brown, mild-tasting species of Tylopilus, T. ferrugineus is the most elusive in terms of ID. I am convinced there is at least another cryptic taxon that masquerades as ferrugineus. T. indecisus has a much paler stem. KOH on context for these two species produces a yellow reaction.

These look like T. ferrugineus.

Last year I found a lot of mild-tasting Tylos, which I IDed as T. ferrugineus. Here’s one example obs 209953. Seems difficult to be completely confident about species ID for these types.
