Indeed, I had seen the (uncited) claim on the wiki article but wasn’t able to track down a molecular study to back it up. That said, the following (outdated!) citation lead me to believe the statement may be accurate:

Murrill, W.A., 1903. The Polyporaceae of North America.-IV. The genus Elfvingia. Bulletin of the Torrey Botanical Club, 30(5), pp.296-301.

“In the present treatment of the genus Elfvingia, E. Lipsiensis (Batsch) [=G. applanatum (?)] will not appear, since it does not occur in America, its place being taken by E. megaloma (Lev.) [=G. megaloma].”

In other news, Index fungorum shows G. megaloma as a synonym, so I am all sorts of confused. What reference are you using?

As far as I know we still have both here in the states and they are treated as distinct entities. A cross section is the best way to sort them out, Applanatum having a layered, lighter colored context. If you’re referencing the Wiki article here , its likely incorrect as there is no citation listed and should be updated. I’m not aware of any published papers making this claim.

Taxonomic change!

Looking a bit deeper into this topic, it appears that G. applanatum is a European species, according to more recent DNA studies of the genus.
