All seems to fit for Hexagonia

except the lower parts of the pores as you say. I haven’t seen them that elongated in Hexagonia in Italy but when you compare photos of it on google there are some pics that also show that feature.
For now best solution is as always: Polyporales ss. lat. ;)

The upper side

is very closed to D. confragosa, and the pores too, but as you said, in most of the photos, it is really more flat. For Hexagonia, comparing with other photos, these pores seem small and the lower ones are more opened, what do you think?

About being a oak stump, it is only a supposition, because there were many kinds of trees, as usual.

Daedaleopsis confragosa is very common

and I know it very well but I never found it on oak, always on willows, cherry trees, birches and the like. Besides it is usually much more flat and the pores are more sinuoid.
I still think it could be Hexagonia. Upper surface would match and in older stage underside too. But not sure of course.

More photos

Hm, does not really help.

Same size as most brackets. Underside looks like honeycomb and not really daedaleoid although I remember Hexagonia from Italy to be totally honeycomb-like. Upper side also does not really look like Daedalea to me. Any further photos?

Ho, here you are :)

More or less 10 cm the bigger, I brought one home with 5.5cm.

Hexagonia nitida to me. How large?
