Based on the overall look and bluish colors in parts of the stem, I’m pretty sure this is a Leccinum species, just not totally confident in which one (L. holopus? No nearby birch trees though). None of the three I found had prominent scabers.
Found near red pine.
Taste not bitter.
Nothing seems to bruise any color. There are some notes of blue in spots on the stem though.
Ammonia negative on all parts, but did turn pore surface red
