User's notes
I'm never comfortable with all the fruit body variability I see in in the suggested species. This one has a much more uniform upper surface colour. Count is of numerous fruit bodies growing out of the side of a long dead log.

The pores seem to be closer to something like Cerrena zonata. While there's also quite a lot of fruit body variation for that species, comparing these photos with iNaturalist I think the colour, texture and margin on the upper surface are far more consistent with C. zonata than a Trametes.

I suspect Cerrena is a possibility. I looked at Ryvarden (1991) Genera of Polypores, Synopsis Fungorum 5 where he accepted Cerrena as a monotypic boreal genus (p112). I looked at Breitenbach and Kranzlin (1986) Fungi of Switzerland Vol 2 where the images there for Cerrena unicolor and for Antrodiella hoehnelii (p279) do show some resemblance to the species I photographed. In this case I suspect the literature I've been looking at is now a bit old. After initial a look on the computer I'd made an assumption that the fruit body was partially deformed as underneath it appeared to show some damage from invertebrate feeding and evidence of a possible pathogen in the green/blue discolouration that can be seen in the third image. I will have to see if I can find it again next year.
