Also, look for anything like a little crater, or black-tipped bumps, or squiggly cracks. Ideally we’d like to know what kind of reproductive structures it has (if any), as well as the texture of the thallus.

But all the species I’ve seen are distinctly whitish or grayish, and always conspicuously ecorticate. This … well, the photo’s not quite close enough to say for sure, but it looks corticate to me.

this is also too green for it?

Seems too green to be Cryptothecia

But when wet, colors are hard to interpret. There are Fissurina which look like this, too, and whose apothecia are virtually invisible from a distance.
