Entirely plausible but need to see underside

There’s pretty much no way to distinguish U. phaea and U. angulata from above, and it could even potentially be U. torrefacta (although I’d be surprised since it looks really black below. The thing to look for is the texture: U. phaea has a coarse sandpaper texture; U. angulata has rhizines; U. torrefacta is paler with tattered “plates” (easier to see than describe!)
