Pileus diameter – 51 × 46 mm
Pileus height – 17 mm
Stipe lenght – 55 mm
Stipe diameter at apex – 9.6 × 23 mm
Stipe diameter at middle – 9.6 × 16.5 mm
Stipe diameter at base – 9.6 × 11.6 mm
Pileus – brown/red, dry, glabrous, cracked (specially near margin) and revealing light yellow flesh, smell is agreable, taste is mild and non-distinctive. Flesh is yellow and does not bruise.
Hymenium – tubes are bright yellow, depressed around the stipe, evenly distributed. Pores are angular and do not bruise. Tubes are around 6.8 mm long and decurrent (go down stipe 4 mm).
Stipe – central, tapered from base to apex, compressed, reticulated (bold brown reticulation)

First of all let me say that identifying boletes is not my forte. That said, I used the keys from “North American Boletes: A Color Guide to the Fleshy Pored Mushrooms” by Bessette A., Roody W.C. and Bessette A.R.
Based on those keys, the B. illudens pileus is described as being pale brownish yellow and becoming yellow-brown to pinkish cinnamon and the pore surface sometimes bruises weakly blue or blue green (the specimen pileus had tones of red on the cuticle which do not seem to fit with the description and, in my opinion, the pore surface did not stain). The fact that the pore surface does not stain eliminates B. subtomentosus, which stains greenish blue. Furthermore, B. subtomentosus is described as having a pileus that is olive-ochre and that becomes olive-brown with age. I did not observe any tone of green on the cuticle of this specimen.
Last, depending on how you describe the stipe (i.e. “yellow, bright yellow to golden yellow or yellow orange” versus “pallid, pale yellowish, cinnamon to reddish brown”) a few other similar mushrooms could be considered. For this identification I considered the stipe to be pale yellowish…otherwise I would have to call this bolete Boletus sp.
A very meticulous and detailed description of this bolete — kudos on that. I don’t necessarily have a problem with your identification, but how did you rule out other similar-looking species, like B. subtomentosus and B. illudens?
