both frustosus and calopus var. frustosus are currently blue on IF.

that Thea found (with the sinuous, red stipe) seems like it was definitely B. rubripes, these might also be. The reticulations aren’t prominent on these fruitbodies, and the caps are really pale and not deeply cracked.

That said, they are developing some large plaques, and I have seen B. frustosus that had very weak reticulum.

should be elevated to species status, since the nominate is a European species. I don’t know if that’s become ‘official’ yet.
These had reticulate upper stipes, although fairly obscure on some.

reticulate or non-reticulate stipe?

can’t tell by your photo.

and whatever happened to Boletus calopus var. frustosus? It is what I would call this if the stipe is reticulate. Is this name in flux? Index Fungorum is little help.
