Xerocomus or not,

it is clear that there is no “glue” between the individual tubes, and they would rupture when pulled apart (so, yes, clearly this cannot be B. bicolor and company).
Another thing is that the name Boletus L., as applied to all cryptic taxa found on MO, is a gross misnomer given what we know about the status quo of this genus from the phylogenetic perspective.

Relatively thick tube layer…

points away from bicolor. But these look to be fairly blown-out specimens. My own experience with bicolor is that large post-mature specimens often develop spongy tubes up to about 0.5 inch deep.

I didn’t measure the tube layer, however, it was quite thick. Thank you.
