Rhizopogons are closely related to Suillus and other Boletaceae.

Only the tubes remain. In Rhizopogons, the tubes have been convoluted, smashed, mashed, and otherwise distorted so that they form a mass of chambers inside the gleba. Remaining tube chambers are called locules. Spores form inside the chambers.

Yes, Daniel, the gleba had a spongy (porous/honeycomb) texture — i.e., it had holes. The texture was fairly homogenous. Than can be seen be rotating the cross-section such that the rays of ceiling light are almost parallel to it. Let me know if you are interested in these samples.

a reasonable possibility. But I don’t see, even at full size, any locules in the gleba. Was this spongy textured? Did it have holes visible in the gleba?

Another feature that has me puzzled: I see pink in the peridium, not the red-staining so commonly reported in R. rubescens.
