Remove the pictures!

Remove the new pictures and create a separate observation for them. They are different.

Spore prints

All of the first set of pictures wouldn’t print, but the specimens in the added pictures printed a dark black. I couldn’t tell if it was jet black or purple-black though.

still doubtful

even the new ones do look like Conocybe, the reddish tinge is apparent in ghe gills and the fruitbodies seem quite mature. In my impression of P. conopilus its cap is grayer and its gills lack the reddish tinge completely.
Obtaining a spore print would solve this one easily.

Course of action?

Should I remove the psathyrella pictures, or perhaps remove all the other ones? I don’t want to confuse anybody.

The new pics you added are definitely Psathyrella, close to P. conopilus. Not sure about the first ones. The gills do not seem to be turning dark brown in maturity.

Maybe more pics?

They were definitely hygrophorous. I don’t think it had been cold enough for them to be frost-bitten, I assumed they were just on their way out (didn’t print either). I found them near a lot of hygrophanous Psathyrella sp. which may or may not have had some healthier speciment of this species mixed in (see added pics).

Growth in large groups on mulch is something Conocybe often do. Cap shape and apparent hygrophanity are also typical of Conocybe, although the specimens in the pictures don’t look particularly fresh and healthy (soggy or frost-bitten?), so it’s hard to tell by looks alone (marcoscopic, I mean).

If you can have a close look at non-soggy caps (i.e. fresh but dry, like the rightmost fruitbody at the last image), Conocybe caps are non-shiny with what looks like tiny sparkles because of their cap cuticle structure (large spherical cells), while Galerinas don’t really change and just become paler and less tacky when the excess moisture in their flesh dries out.
