Thanks for the info; was not aware of the possible sameness of the two. In reality, there is no way to tell off of the photo per se; I believe most here choose tsugae by location by default. Very interesting taxonomic information that demonstrates that tsugae is reishi as well, and not similar, but possesses more sameness than not.

My understanding…

is that American collections of G. tsugae and “G. lucidum” are nearly identical besides choice of host and context color (G. tsugae whitish when fresh, G. lucidum brownish), and probably microscopic features.

My point with suggesting that name is that without knowing any of the above mentioned characteristics, it’s hard to really say what you have based on the pictures alone. Unless there is some blaring field mark I’m missing, which is always a possibility.

And, after more research, I guess G. lucidum is considered a deprecated synonym for American specimens, with G. sessile being preferred by many.

Didn’t catch the tree, but there was a pile of them growing on a horizontal downed rotting log on an island in the river nearby at the top of the island, as well. I understand that you weren’t asking for the substrate that the trees were growing in, but since when is a tree that is mostly alive considered substrate? To the “lucidium” maybe-er, is lucidium present here? considering the vast prevalence of Tsugae fruiting, what would be the percentage probability of lucidium? 2%?

Was it growing on hemlock or at least coniferous wood?
