this species well at all, Igor. The dark, almost black color of the cap seems to point elsewhere. But I can’t think of a better candidate, and I trust your expertise enough to defer here :)

(And no, I’m still wandering the woods free of chemicals and microscope. I hope to get some of the appropriate paraphernalia soon, though.)

Logan,

Check out Ron Pastorino’s obs 280000 from TX, which I think could well be the same species and which I will hopefully sequence later this year. Dark cap colors and densely and deeply pitted (almost reticulated) caps are rather unusual for a classic separans from the northeast, but what else can it be? At the very least I expect it to be a closely related entity. Did you try the ammonia test?
IMO, it would make sense to vote up the separans proposal to at least “could be”.
