clearly this is no Mycena pura, with its hair-like stipe!

Gills widely spaced, thick. Purple color bled off into water when rehydrated. Pileipellis an irregular epithelium.

Spores in water and Meltzers: amyloid, round, with a thin, clear collapsing shell that is ellipsoid. Blue spore center round (sometimes all that was shown) ranged from 5-6 microns. With shell: 7-11.5 × 5-6; 11.5 × 6, 7 × 6, 8 × 6, 9 × 5, 9 × 6.

Basidia with fat base and two elongated sterigmata. No cystidia observed.

I agree

Too small for the entity we call P. prunulus around here.
More like this, which I found on the UCSC Campus earlier this year:

well, it IS purple…

but I think that it is too thin fleshed as well as being ridiculously tiny to be Mycena pura…look how the redwood litter dwarfs the mushroom! It was less than a centimeter across…
