These kinda look mostly like Mycena, but maybe you should check spore color? Perhaps they look a little Entoloma-like also?
But if they are wood, they look like M. abramsii perhaps. But also with the long. striate stipes there is another Mycena they look more like… and the name escapes me now… Oooh, this is going to kill me, and I don’t have to book to look it up, it is in the SMG library…
I think maybe Mycena polygramma is what I am thinking of, with the grey long. striate stipes.
Just some ideas… I would say the one from last Nov. is similar, but what you show from this time past year, I don’t think so. That one is too brown, and also not sure it is really Mycena.
