Notes:
Nice to finally identify this species, also seen last year. The key event was finding a large colony of them on that stub-path in Zone 45, overturning one of them, and seeing pores. Knowing it was a bolete led me to the right keys to stick a name on them, and it’s virtually unmistakable by its field characters and geography.

The tree associate, Pinus strobus, is in the area and is in fact one of the commonest trees in these particular woods; the previous sighting sites, Zone 05 in particular, also contain it (05 is dominated by a 3:1 mix of Pinus resinosa and Pinus strobus, with a smattering of hardwoods such as Betula allegheniensis, for example).

Last three photos attempt to show the fibrous part of the partial veil on a young one.
