Recognized by sight: i can’t see whether there are fibrils sticking out at the base of the stipe, but the rest reminds me strongly of Pseudobaeospora (the spore sizes fit well for that genus).

I agree with Else – once I saw how small the spores were, Pseudobaeospora jumped to the top of the candidate list. I have confused them with Rhodocybe before, but as Else also mentioned – the often strongly strigose-spiky basal rhizomorphs can be a good hint.

Reminded me somewhat…

of Cortinarius flexipes (which I find here in eastern NA), a small gray to purplish scaly/umbonate-capped mushroom with whitish deposits on the lower half of the stipe. I have found it in mossy areas. Actually, the spores being smooth for this obs appears to eliminate anything close to C. flexipes.

Spore print color could be useful here. My guess is these are not white-spored, which I suspect would eliminate Neohygrophorus.

Don’t look much like Cortinarius.
Overall, I’m most reminded of Neohygrophorus angeleisanus, Rhodocybe and Pseudobaeospora, in that order.
