The anthraquinones may have leeched out completely. I looked up sorediate/isidiate species in the British Flora, but none are even close. The “soralia” look more like something is eating it. Taken together with the vast dead zone in the center, and the apparent lack of any actual soredia (just excavations which may have given rise to soredia at some point in the past), I conclude that it is damaged, not actually sterile/sorediate.
I defer to your opinion between C. aurantia and C. flavescens (and _C. saxicola? others?) I’m just commenting on the odd appearance of the thallus, suggesting this is probably due to damage not morphology.
