This could be a Dermocybe or a Cortinarius. There has been swapping between these two genera and it seems that many Dermocybe species will return to Cortinarius. In order to have some confidence of a fungus being Dermocybe/Cortinarius (especially when the colour is a fairly ordinary brown) I like to see (1) evidence of rusty brown spores or (2) at least some traces of the flimsy partial veil. Ideally, I'd like to see both. Here I cannot see for sure.
