The colour of fresh crusts is a fairly distinctive salmon-pink. Perhaps the colour deepens to a light brick red if left to age? Older or damaged crusts may also perhaps be an angrier orange? The white margins are said to be persistent, and quite substantial and clear, sometimes a bit fringed apparently. Should be easily separable from its substrate according to Lassoe and Peterson, but not Kibby, who says it is firmly attached.
The pores are often angular or even labyrinthine, but usually look quite evenly spaced in my very limited experience. Sometimes angled if growing on upright or angled wood, perhaps gradually turning somewhat lacerated. Found on a wide range of fallen or still-attached dead deciduous wood. This looks as if it could be on Beech. As it dries it should turn from soft to brittle.
I've now found it a couple of times in Dene Park, while Hugill and Lucas have it as uncommon, 5 - 7 pores per mm with a somewhat musty smell they claim, which I haven't checked.
