possible Ganodema applanatum - Epping Forest

Observation - possible Ganodema applanatum - Epping Forest - UK and Ireland. Description: Very large bracket fungus growing on an enormous ancient Beech in Epping Forest. The edge of the bracket seems very thin, leading me to believe this might be Ganoderma applanatum rather than G. australe?
