On a rotted log in Burgh Wood.
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.
We need larger photographs with a clearer view of the surface. I don't think it is a Punctelia. An interesting idea occurs to me, but I don't want even to speculate.
I will look for better among my files.
I found the log on the floor - I wedged it in a couple of branches to photograph - I might be able to find it again if necessary :)
