but there are much too few collections/sequences to be satisfying.
It clearly separates the varius group from melanopus and badius, but it was already assumed there that leptocephalus, elegans and nummularis were synonyms to varius. I’ll keep looking for more..

To what extent is our understanding of the speciation of black-footed polypores supported by DNA evidence.

that only the base of the stem is black on leptocephalus (varius and elegans are considered to be synonyms!). P. badius has a darker brown cap.

P. leptocephalus (with a pale yellowish brown and fading cap) is often mistaken for melanopus, but the latter usually has a grey cap, is rather fleshy, and the whole stem is velvety and slowly turning from greyish to black.

black foot polypore? what makes P. leptocephalus different from P. melanopus, P. badius, P. varius and P. elegans?
