I plowed through Smith’s Boletes of Michigan for some time, but couldn’t make sense of this one. I never saw the yellow staining stem base mentioned anywhere (outside of Agaricus), and few have such long narrow spores. Seems clearly in the section Boletus, but I can’t figure where to go from there.

And once again I must apologize for not having a photo.

And without a proper drier, I’m not entirely hopeful this thing will dry before rotting, so the “Herbarium Specimen Available” might be overly optimistic.
