The BC collection

I would call the collection in Observation 31962 M. amicta too. Smith has extensively studied both species (amicta and subcaerulea), was searching for the latter in the PNW and never found it. Except for the preference of the latter for hardwood forest habitat, there is virtually nothing that you can use to distinguish them in the field. Microscopically, there is an obvious difference in the shape of spores: they are narrowly ellipsoid in amicta and (sub)globose in caerulea. Thus, without checking the spores, there is no justification to call M. subcaerulea any blue-tinted Mycena found on the West Coast.

There were a handful of characters that seemed to favor subcaerulea over amicta in image matches, and I had misremembered that both occurred here.

Why subcaerulea and not amicta?

M. subcaerulea does not seem to have been recorded in PNW/CA. It looks like M. amicta I’ve seen, but the species is variable, it may be very blue too.
