No specimen available

Posted this back in 2008. Just ran across a few extra pics and some notes that I had taken for this mushroom. KOH on the context turned brownish. The spores are large, even for a Boletus. Mix of pine, hemlock, and oak.

my original notes did mention hemlock.

Boletus inedulis

is what I’d call this too and this is the stature of the mushroom as I usually see it occur in hemlock forests of CT.

Just read the interesting discussion for obs 47327.

Sounds like B. calopus (whether it be the actual European species or an NA counterpart) is unlikely for my obs 18474. Kuo mentions that inedulis may occur with faintly reticulate spem, which this one seems to exhibit. (I had been using mostly small file photos at the time of this obs.) This was found in mixed woods, primarily oak. Haven’t seen another one like it.
