I am unsure if this is Crustose or Foliose yellow 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.
These are crustose lichens. The 'cup shapes' in the second photo are the apothecia or fruiting bodies.
Thank you Jenny,
Looking through other pictures I was unsure. I know what to look for now :-)
