I agree with Dave…

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.
