I thought that must be what you were getting at.

Like I said, the resolution wasn’t good enough for me to see if that was true or not. Thanks for the words. It’s nice to know I actually was on the right track even if my glasses were missing!

The pores…

…are “stuffed” – i.e., covered by the dense and conspicuous layer of cheilocystidia prior to maturity. This is the “trademark” of the porcinis, though some other boletes (e.g., B. auripes and a number of Butter Boletes) also feature this partial veil-like structure as a symplesiomorphic trait.

Looks like…

…a single taxon to me based on the pictorial evidence. The light-colored fb with dark brown reticulation in the title thumbnail originally gave me an impression of R. griseus before I blew up the photo.
I don’t know porcini well enough to ID this to species, but it’s obviously a representative of the porcini sensu stricto super-clade, which consists of the edulis clade, the variipes clade and the aereus clade in the sense of Dentinger et al. and Feng et al. My best guess it’s either in the variipes or aereus clade.

I’m not going to get it.

I’m assuming there’s something about the pores but I don’t have the resolution to see it if it’s there. I can see some white netting at the very, very top of the stipe but I saw that as part of the white pore structure more than the stem reticulation.

Please share. I’ve no doubt you’re right, particularly since you both seem to agree, but I’m not seeing the footprints that led you guys along that path.

The brown-stemmed one looks easier, but I would actually venture a guess toward variipes there.

This is not Tylopilus. The question you have to be asking yourself is what definitely makes this a porcini. Hint: the important detail is in the pix.

Also, do you have two species here?

One with buff colored stipe and the other with a brown stipe?

Dark netting, white pores… Why aren’t you guys leaning toward Tylopilus?

You both know better than I do, so please consider that an actual question.
