No specimen available

Paging through my books, I see some that look a bit like it, but none that look the same. I found it in my compost bin today.
Odor: Uh, smelled like a compost bin, but maybe due to where it was.
Taste: Didn’t taste. :/

Opening the bin caused the shrooms to stop growing, dry, and die.
If this happens again, I’ll crack the lid open, only.

Yes, since Daniel W. mentioned the air, I thought I should open the bin. OK, I shall open today.

I cut it open, as well as showed more of the substrate (seems a combination of wool, a little human hair, and coffee grinds with filter). I’m adding pictures that should be up in the next 10 minutes. Oh,a nd I also took the cap off one of them.

And see if the influx of O2 halts the stipe etiolation and allows the caps to expand. They’re too undeveloped to ID in their current state.

This looks like monocot roots from something like an onion. What is the fungus growing on? Did you slice on of the long, root-like structures open?

Daniel, that’s a really good possibility. Yes, it is quite enclosed.

Unlike anything I’ve seen before, Sam.

Was this an enclosed compost bin? Could it have high CO2 levels? Does it have a lid on it most of the time? Did it have slats on the sides for aeration?

Fungus looks as if it is searching for air, much like Ganoderma lucidum forming antler-like shapes looking for air. Only happens in high CO2, though.
