Parasites that grow on lichens are extremely diverse, far more so than lichens themselves. There are few comprehensive sources for lichenicolous fungi yet.

I don’t know much about this.

You mean parasitic lichen? Or Ascomycete fungus? What are the options, as far as species go?

I’ve no clue

Are the black apothecia a parasite, maybe?? The green frilly patches look neat, too.

Never mind those dark spots.

Those are intrusions of another lichen. Apothecia can be seen in this picture too (second photo), but they’re so tiny my camera can’t really show them. They’re black, with rim, perched on top of pimples of thallus looking like they’re not attached at all, and if you blow at them they’ll fly off. Peer at the photo at highest magnification, and you’ll see tiny black dots – but they’re very scarce.
