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.
It's a lichen, and therefore should be placed in the Fungi category.
The teeth (rhizines) are visible in the photo, but the upper surface isn't bullate and tomentose as it is in P. membranacea.
I suspect this is P. hymenea, but would want to check the veins on the underside.
