Green/grey, yellow lichens with strange white stuff - another lichen?
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.
Yellow lobes are Xanthoria parietina, bluish-grey ones are either Physcia tenella or P. adscendens. Can't see detail clearly enough for the white one but it is a lichen
