It doesn’t look like X. badius. I think B. rubropunctus is much closer to the pseudo-leccinums, such as B. subglagripes and B. longicurvipes (maybe those have already been moved to Leccinum). In fact, if you subtract the red coloration of the stipe, it will look very much like B. subglabripes.
I’ve collected both (?) in the NJ Pine Barrens under scrub oaks (see my observations 74478, 73650, 73649, and 55018). The varying degree of redness on the stipe creates a confusion with the southern form of B. subglabripes (if it’s still recognized).

Nice one Igor.

Well photographed.

Is this close to B. badius? Reminds me somewhat of this conifer-associate.
