Bill, Daedaleopsis…

is an interesting proposal. Some of the pores in this specimen show the angled slot-like appearance seen in these types. Also, this mushroom was found on birch, a favorite host of Daedaleopsis. I did not bruise the pores to test for staining. My plan had been to return to the site and collect the specimen after it had a chance to (possibly) further mature. But when I did return after about 10 days, the mushroom and the birch log, had disappeared. No big rainstorm/washout… so it was a bit mysterious to me.

I’ve seen Daedaleopsis confragosa take on that manifestation. I think it might be that.

Beautiful and very interesting. These look a lot like the homes of a certain species of paper wasps I have seen.
