Two species in the eastern US were previously called G.lucidum, one with a stipe and one lacking a stipe. Both grow on hardwoods. G.curtisii is a stipitate Ganoderma with semi rough spores. G.sessile is a sessile Ganoderma with smooth spores. Both have been shown by DNA studies to be unique from Ganoderma lucidum with has rough spores and grows on hardwood. Ganoderma meredithae is a version of G.curtisii which grows on pine in the south.

Based on morphology I agree this observation is G.tsugae.

G. lucidum may now be know as G. cutisii according to some previous obs. It also is found on deciduous wood whereas G. tsugae is found on Pines/Hemlock.
