This was growing on what I believe was a Sycamore but not sure if it is a lichen or fungus so if anyone can put a name to it, many thanks.
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.
Many thanks for the ID.
