So that’s the question

You need a key of course for determining Phellinus species…
E.g. Phellinus ferruginosus has much narrower pores and long “arrows” all over the fruitbody, Phellinus contiguus has wide pores, but you cannot apply European key to America … but ferruginosus is a very common one in Europe on deciduous wood.

thanks Gerhard, that’s helpful…

but what if anything is the difference between hymenial setae and setal hyphae??

Microscopically in Phellinus

hymenial setae and setal hyphae are very characteristic – those pointed brown arrows around the whole slide … it looks a lot like P.ferruginosus if it would be in Europe (or P.contiguus) but no species name for North America!

sure looks like this one…

and apparently, it also grows into a conk shape??? (see other MO sightings),
but what are the micro characters for confirmation?
