That was my impression today

The only area I could make out anything similar to reticulations was near the apex of the stem with the cap removed. I couldnt see this in person and only noticed it in the picture, the lines also appear depressed. I suspect these FB’s have been around for some time judging by the look of them, probably because of the cold weather slowing the insects down.

The variability in the observations you linked is astounding! I wish you the best of luck trying to sort these things out.
Edit: sorry I forgot to mention I did not taste these, they have a kind of sweet musty smell. Both times ive found these they were pretty old looking so I have avoided taste test so far.

Not reticulate

I would call it a pretty much smooth stipe. There might be some obscure ridging or wrinkling, but IMO it’s not even enough to be called a textured stipe…
It’s interesting how these fruitbodies lost their original red cap color, fading to grayish-tan, but retained the dark red pore color. In this condition they even somewhat resemble Caloboletus firmus. Speaking of which – did this collection taste bitter?
I am not going to venture any more guesses here. Let’s wait for DNA data to transpire. Patience should eventually pay off. :-) I’ve been already fooled by some ostensibly discrete-looking red-pored species only to be disproved by DNA results. For example, obs 206608, obs 244427, and obs 251141 are conspecific as per their nrLSU and TEF-1-alpha sequences (not all the info has been entered into those obsies yet). How do you formulate a species concept for such a chameleon?!

I guess they are faintly reticulated, although when looking at them in person I cant really tell.

Stem ornamentation

Both collections appeared to be very faintly reticulate, but its hard to say for sure. This might be because of age since i haven’t yet seen a young fresh fruit.

I will try to go back to the ones I left behind and get a better picture of the stem this afternoon.

Is this collection reticulate? I’m having trouble seeing stipe ornamentation detail in the pictures…

Thanks Igor

I look forward to hearing the results! Your time and resources spent trying to shed some light on this find is much appreciated.

Have a good evening.

Thanks for posting this interesting red-pored bolete again. Your original collection (288137) is already off for DNA sequencing.
I gave a bit more thought to the possible identity of your bolete. It looks a bit like Boletus fairchildianus, based on the pix in Boletes of Eastern North America, but… there are some notable differences vis-a-vis that species, such as the extreme southern distribution and the association with oaks rather than pine.
