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.
This this is a fungus, not a lichen. See my comment under your Cladonia post. It is not always easy to separate lichen from fungus, but it soon comes with a bit of experience.
