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.
Most of this image doesn't look right for P. sulcata. It's difficult to be certain without a clearer shot, and maybe not even then, but there appear to be white dots (pseudocyphellae) on some lobes, which makes me wonder about a Punctelia sp.
