maybe I could…

if I had YOUR macro lens! yes, there are some pathetic patches of pores on this critter tucked up in the gap on the left bottom side of the fruit body.

Jessie Glaeser has offered to take a look at it (a piece of it, at any rate) in hand, as well as possibly run the DNA if microscopy doesn’t provide an answer. Should be quicker than getting in line for the DNA analysis at UCB! ;)

I said Fomitopsis pinicola as well. I thought maybe it froze when it had “sweat” droplets on it…

Pores were formed on the left underside, maybe Debbie can take a picture and post it.

I thought so too, Tom.

But this one is definitely stumping the stars!

I also sent these photos to your WI polypore compatriot Dr. Jessie Glaeser, and one of the names that was proposed was an old, spineless Hericum. Too woody for that, tho, IMO.

Anything definitive to Fomitopsis pinicola that could be seen in microscopy? Or should I just let it go and wait for the DNA?

I suspect is is a mutant Fomitopsis pinicola

Sometimes mutation occur or conditions are such that the pores form wherever they want without regard to gravity. And Fomitopsis pinicola is so enormously variable anyway. That’s my best guess anyway.

not bitter…

back to the drawing board.

Just an idea

that if this conk has the same corky and tough texture as Fomitopsis pinicola (which it definitely isn’t), it could be Laricifomes. I don’t actually beleive it though, I’m sure Darv would have recognized it if it was..
Why not try to find spores to start with? Maybe it’s too immature.

what qualities would make it so, Irene?

I do have the fruit body here…and a sharp razor blade!

I agree, Darv, that it is the same thing found by Allen…but what it IS is still a question mark, IMO.

Another?

This observation might be the same species.

indeed, this was a strangely textured fruit body…

but a solid, heavy “conk” nontheless. it has a similar tho more exaggerated texture to this more obvious Fomitopsis that I just posted in addition.

It’s not a Pycnoporellus, tho, which has a pretty airy, chambered fruit body. colorful, too, unlike this white fungus.
