Trametes versicolor?

Observation - Trametes versicolor? - UK and Ireland. Description: Think this maybe an old colony of T.versicolor. It was clustered around a fallen decaying branch on the edge of a woodland ride. I think the branch must've rolled over as the 'zoned' surface was hidden from view initially. The white underside surface, see

Think this maybe an old colony of T.versicolor. It was clustered around a fallen decaying branch on the edge of a woodland ride. I think the branch must've rolled over as the 'zoned' surface was hidden from view initially. The white underside surface, seems to have taken on an orange colour, possibly due to a secondary fungal infection?
