From where I sit they look more like fungi in the genus
Peziza (inedible) as the
cup is facing up towards the sky & they are growing from the soil. Exception: some
Peziza species grow from wood chips.
Fungi in the genus
Auricularia (edible) all grow directly on wood, as far as I know, & their cups face
downward towards the earth.
Note: animals, weather, humans, etc can sometimes turn the fungi over & make the cup-facing direction a bit more difficult to decipher.
Another way to tell the difference between these two genera is that
Pezizas are brittle & crack & break when you try to bend them, while wood ears in the genus
Auricularia bend without breaking & feel ...well... kind of like an ear when you grab hold of them. :-)
It is recommended that you never ingest any fungus until you have 100% positively identified it as edible
down to species. This means using a key to confirm all of its morphological features (in some cases this means using a microscope even!) &/or asking your local expert mycologist(s) for assistance.
