Used references: Aurora’s Mushrooms Demystified, p. 563 under P. arcularius. Much depends in Aurora’s key on the size of the pores per mm. However, this is the only Polypore which has a stem that does not turn black/brown/another color than white.

Recognized by sight: Polyporus badius has very thin flesh and is very leathery and large. Polyporus brumalis is smaller with thicker flesh and much more ephemeral. I suspect the younger ones in these photos have not yet developed the black stem. Microscopically P. badius is the only species of Polyporus without clamp connections on the hyphae, so that would be an easy way to decide, if you have a microscope. This is pretty typical eastern Polyporus badius, which does not look much like what some are calling P. badius in the west. Someone needs to work on this.
