I am curious. Anyone know what this guy is?
I’m curious as well and guessing maybe ~~ birch polypore, birch bracket, or razor strop ~~?
Fomitopsis betulina https://en.m.wikipedia.org/wiki/Fomitopsis_betulina
It doesn't resemble any of the other birch polypores around here.
Let me guess, you put this into some computer vision app and it guessed a polypore from a photo of a gilled mushroom because it saw birch bark.
Sadly no, I typed up the description on Brave search; it took a while because I used common words:
“Mushrooms that grow on tree branches sideways possible orange color” and variations of without using punctuation and the +/- symbols.
Now that you mentioned it, if there is a computer vision app you can recommend I would very much appreciate it. I’m not tech savvy and using an old iPhone if that helps. Thank you.
I use iNaturalist but it's pretty hit or miss (the bark thing is one kind of mistake I see it make frequently).
Got it, thank you so much! I agree with your statement regarding the bark as I was looking at the photos from Wikipedia.
I’m delighted to see that iNaturalist works on birds as well; my references are mostly books and journals with questionable illustrations and photographs.
Thank you so much, you’re lovely!
Unfortunately it's on the side of a rock face, so I can't get any closer. It's in Sweden if that helps.
Looks like it could be a Funeral Bell (Galerina marginata)
Well good thing I don't Forage. Cause I thought those looked like some damn good pink oyster mushrooms.
Oh wow, I didn’t know those guys grew on upper tree branches. Nice photo, thanks for sharing.
They look a little big/stocky to be Galerina marginata IMO. I don't think it usually clusters that hard either.
Maybe something like Armillaria mellea it's hard to tell for sure.
