On fallen, but still alive, willow in wet woodland though only loosely attached. Spread along about 2 meters of the trunk.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I've found this also in grassy areas, and with moss. I thought it was a type of lichen rather than fungus..... but no idea other than that.
