The germ pore is inconspicuous in many Pholiota species, often requiring the maximum magnification be used to view it, and in some cases the feature may not be seen at all.

Pholiota?

Pholiota? Really? I don’t see a germ pore in the spores.

Looks dead on for Pholiota, and the micro characteristics seem to support that.

Spores suggest Hebeloma

Those spore do suggest Hebeloma, but that wouldn’t be growing on wood. Need to try and make sure it isn’t a Pholiota, which would be on wood. Were there any pleurocystidia? Pholiota should have a germ pore, but the germ pore on a number of them is pretty small. Hebeloma spores should be ornamented, but this is only from the outer layer of the spore breaking up, and look like a slight roughening of the surface, and some look mostly smooth. The spore shape looks ok for Hebeloma…

That’s what it reminds me of most at first glance.
