Intriguing find, but…

…they don’t seem to match up with Stuntzii for the following reasons IMO: Degree of bluing of stipe beyond annulus ring quite uncharacteristic; Degree of oval shapeness of the caps in cross-section with loaf of bread shape and some incurved margin, lack of umbo or slight pointed umbo as opposed to broader nipple-like umbo, amount of whitishness on many of the stipes, and last but not least the rather small stature, they look about half the size of typical PNW stuntzii IME. They seem to share more characteristics with P. ovoideocystidiata or P. aztecorum IMO.

Two species

I don’t think P. aztecorum (formerly quebecensis) is expected to grow on woodchips at all; I think the most glaring factor that points to two different species co-occurring is the very heavy bruising (which is often considered atypical for P. stuntzii) on the specimens that ALL ALSO lack the blue ring.

Psilocybe stunzii (or similar) in New England:

Though I’d be cautious in assuming that there are two species here, since some fruits resemble P. baeocystis, I’ll note that similar finds have been documented from CT and Maine, though Alan calls these P. aztecorum (=quebecensis). I’ve been meaning to ask him why, because I’m not sure I agree based purely on macromorphology, but I trust his judgement implicitly. The only reason I’ve seen him give is the range, and if this is the case, I still believe there’s a chance that P. baeocystis does rarely occur in New England, especially because if they are co-occurring here with P. stuntzii, it seems possible that wood chips containing Western species have been introduced to the area.
