I did notice there were some differences and figured I would need someone more seasoned to know the specifics.

The species…

Royoporus badius (formerly Polyporus badius) is a robust polypore usually with shiny chestnut brown cap surface (sometimes pale). I see it most often growing directly from downed logs.

The ones seen here appear to be growing attached to a birch branch along the area where the branch makes contact with the ground. This is a common growth habit for P. leptocephalus. This species is also called Polyporus elegans, and is probably also the same species as P. varius… at least the variety of varius that most often occurs in in NE PA. The amount of black on the stipe varies with this species. Champignons du Quebec and RogersMushrooms each describe the species P. melanopus, a similar polypore that appears to grow terrestrially and features a long rooting stipe.
