Used references: The photo at this site:
appears to have the same dark chocolate-brown staining or exudate. The name, according to MO, has been deprecated to Onnia circinata from Inonotus circinatus. From the Northeastern US. Sure looks different from other west-coast Onnia circinata here on MO, though.

Recognized by sight: Polyporaceae s.s. does not include Onnia, if it’s an Onnia at all. this versatile little creation, however, means “has pores,” proper taxonomy be damned!

Recognized by sight: possibly a pre-rosette/-imbricated fruiting

for at least a suggestion of what this could be. Your link proved valuable, but unfortunately proves this obs. can’t be it.

Pseudoinotus doesn’t have a stipe. This obs. has one. Pseudoinotus should have yellow-tinted to buff-colored tubes. White tubes bruising or staining yellow or maybe greenish-yellow are present. Finally Pseudoinonotus produces an amber-colored exudate. I’d call this more chocolate-brown to chocolate-black exudate.

So not likely that species. Maybe a different Pseudoinonotus, or even Inotus?

That “staining” is really something out of the box.

Cool find!

Albatrellus. I think.

Based mostly on the scaley pileus with soft “fleshy” texture. I also think this is a species novum, as I have been unable to find a single Albatrellus with chocolate-brown to chocolate-black exudate, which I would describe as copius.

Please look for more, and dehydrate for voucher collection, Richard. Oh, and congratulations, I hope: usually species novum are named for their finders.

coloration is correct.
the fungus was fairly soft.

Chocolate-brown to chocolate-black exudate from pores?

Can you confirm that coloration? Was the fungus hard or soft?
