Found this kinda small (~1.5 cm cap size) guy, with a long thin stipe, so my first thought was Mycena. But got it home, and got a spore print, and it is brown, just like a cort. So, this is some Telamonia Cortinarius, with a long thin stipe. I haven’t seen one like this before, so not sure what it is.
