Gloeophyllum sepiarium

surely Gloeophyllum. Daedaleopsis never has a hariy surface. The wood is either pine or spruce

is definitely an option on hardwood. Usually with shorter “pores”, but extremely variable.
As you say, it can also occur on conifers, as well as G. sepiarium can be found on hardwoods.
One way to find out for sure, is to check the wood. Daedaleopsis causes white rot, Gloeophyllum causes brown rot.

Conifer logs usually have branches that stick straight out around here, and in a spiral arrangement. This has a branch at a 45 degree angle. The bark does look more like on some of the area’s pines, though.

Lincoff has two polypores resembling this, L. betulina and Daedaleopsis confragosa, and it states that the former and implies that the latter sometimes occur on conifers. Lincoff’s photo of G. sepiarium resembles this less, but some web photos of it resemble this somewhat. And according to Lincoff, G. sepiarium sometimes occurs on hardwood.
