Actually, I had thought this may be an old specimen of badius. I believe there has been some disagreement (at least within the NA field guides) regarding the names of these thin hard-fleshed polypores with the black stipe base. The “blunt cap margin” for P. leptocephalus seems like a good piece of info.

That’s how R. badius looks in old age. Polyporus leptocephalus is seldom around late. It is usually much smaller and fruits on twigs and small limbs. R. badius fruits on logs and stumps.

Polyporus badius has a thin cap margin and smooth, shiny cap surface, and hyphae with clamps.
P. leptocephalus has a blunt cap margin and rough cap surface, no clamps. It has several synonyms (and it probably consists of several different species..).

P. leptocephalus. Amongst the multitude of synonyms, I did not see P. badius. So I’m wondering, is P. leptocephalus a synonym for P. badius? And if not, then how dos one tell these two types apart?
