If this sort of shape (stacked, fused surfaces of revolution) is characteristic of this species, perhaps the name Ganoderma roswellii would have been a better choice for the taxonomists to make? :-)

agreed

Yeah, Looks a bit like Ganoderma applanatum

I would say remove it from the tree and take a pic of the underside, but removing it would require a jackhammer or splitting wedge…haha

Some sort of Ganoderma maybe

I would suggest … but I’m not really convinced of that:)
