but you don’t know to a certainty that this one was actually growing with the birches. ;-)

L. atrostipitatum is not a conifer associate. Unlike other boletes, scarber-stalks are remarkable mycorrhizal specialists.
You can try to key it out in Smith & Thiers, but chances are this is not a known taxon.
