Ok, what to name to give this one.
Staining bluish-green on stipe ext, flesh staining vivacious-purple becoming grayish-purple to purplish-black, sometimes bluish in stipe.
This is what we usually call L. aurantiacum which probably doesn’t occur in North America and grows with broad leaved trees in Europe. Supposedly L. vulpinum is our common orange cap leccinum associated with conifers, but it has black scabers…

to beleive that you can have some european species in Massachusetts, and call this Leccinum aurantiacum. If a wide host range is accepted, it is known to be mycorrhizal with Populus, Quercus and Betula, rarely with Salix, Fagus, Castanea and Tilia. Any of those trees within host capacity, 50 meters or so?
