Orange-coloured lichen, quite uniform in texture. Found mainly on the North sides of many oak trees in the area, quite dense in some cases.
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.
There is something like that at the edges of the image. I have agreed with the Lichen as it is closest to the center of the image.
