Cap surface?

Did you check the quality of the cap surface? With the brown spore print and the large germ pore, this could point to Conocybe and such.

Not Entoloma

Entoloma spores are always somewhat angular, and there is no germ pore. Also, if it was Entoloma, the spores would be at least salmon-brown, not just brown.
