Ganoderma applanatum or lipsiense

Description:

Ganodermas from two locations, in first two they grow on fallen linden old tree and on third those specimens grow on birch three stump. Third one is definitely Ganoderma applanatum, while first two young ones can be traced to Ganoderma lipsiense. Those two are too similar when young. Can you help me out?

Habitat:

first two versions grow on the fallen linden tree and third image is taken in cut down forest area (cut 10-15 years ago) and they grow on birch stump.
