Observation 97921: Gloeophyllum sepiarium (Wulfen) P. Karst.
When: 2012-06-21
No herbarium specimen
0 Sequences

Daedalus, based on thick, conk-like texture and maze-like thick gills on the underside.

But the photo looks most like Phellinus gilvus in Audubon Society Field guide to North American Mushrooms, which should have pores, not gills.

Proposed Names

29% (1)
Used references: On-line photos of Gloeophyllum show G. trabeum to have much more blunt gills which are more maze-like and less linear. There also appears to be a greater agreement with the raised reddish-brown fibils or scales near the center of the sporocarps. G. sepiarium appears to have thinner gills, which are more crowded, and less likely to be on conifer. The bright yellow on the edges of the growing surface seem consistent with fairly young sporocarps. But this specimen was quite hard and woody. I was able to rip the small section shown in close-up off, but that amounted to less than 1/3 of the total shown here in the first photo.

Thank you Hendre17 for suggesting Gloeophyllum.

I believe you have the right genus. I question the species, though.

Come to think of it, I sort of question G. trabeum as well. Most of the photos of Gloeophyllum on-line suggest much thinner gills than this obs. Then there is the basal attachment on the close-up which appears yellowish, at least as torn. Should be brown.

Tried to find a key for Gloeophyllum, and barely found any data excepting a list of species.

Comfortable calling it Gloeophyllum. Not convinced of the species yet, not even G. trabeum. While G. trabeum is more maze-like and less linear-oriented than G. sepiarium. Then there is the bright yellow edge of the sporocarp. G. sepiarium photos show mostly white edges. I can find no photos purporting to be G. sepiarium with raised central scales or fibrils which are reddish-brown, as this obs. shows.

Would anyone like to suggest another possible species?

On Western hemlock.

Just saw I didn’t include what it was growing on. While Red alder was nearby, this particular downed log was blowdown Western hemlock. Phellinus gilvus said to favor hardwoods, another point against this being P. gilvus.
