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.
Looks like Sulphur tuft to me. But hard to be sure considering its condition.
This was growing near much younger sulphur tuft, I guess this was an earlier growth.
