If you could take a look at the hymenium in the microscope, you’d find plenty of large, dark brown and thickwalled setae, if it’s Phellinus pini..

Thanks Darv

Looks good. Google image search turned up http://www.atlanticetudes.fr/phytosanitaire.php which shows similar brackets on a pine trunk and http://www.nagrzyby.pl/index.php?artname=gatunek&id=114 which shows the same distinctive pores-falling-apart on an aged specimen.

Interesting that these are somewhat different looking from Phellinus tremulae, which also grows in these woods but on aged aspens.

Phaeolus schweinitzii

how do you think we will succesfully id a a old rotten winter lasting polypore?

Isn’t that terrestrial?

And with a paler pore surface? The Google Image results suggest so.

The devil of it is, I think I saw something like this obs once before, identified as something else, but can’t for the life of me remember what or where. Neither my Lincoff nor my Petersen has a close match.

What do you think
