Looks fine to me. If you are able to identify it as a Daedaleopsis species, you’re home and dry since Daedaleopsis confragosa is the only known UK species, is very common, and typically grows on willow. Old specimens can turn deep blood red which can be misleading. Some specimens can also have elongated pores – but never as completely gill-like as those of D. tricolor. The latter keeps being reported from the UK, but (as far as I know) is not confirmed as being British.
