Collected and photographed by Sidnee Obersingleton. “The location was at roughly 500’, outside of Eugene OR behind Lane Community College. The forest was mostly Doug fir with some oak and bigleaf maple, this branch was unidentified but my gut tells me it is oak. Old enough to be coated in mosses and plants, the log was pretty well decayed.”

Sent for sequencing via Oregon Mycological Society. Results are included in comments below.

at all possible, I can try to obtain a specimen from Finland to compare with.

Thanks so much for posting the comment with the sequence data. I’ve also added the sequence as an MO Sequence.

This is 99-100% similar to 10 “Polyporus tubiformis” in GenBank, which doesn’t appear to be a valid name.
