I think these are their own thing. I saw a lot of things-that-look-like-this mixed in with other lichens. They USUALLY do not cover the entire whole rock but here is one where they have covered the entire rock.

They are not rosette-ish nor do they appear to have an order to them. They're just small greyish leaf-like bits with little pimples or whatever on them. (Hopefully you can see that in the full-size pictures.) I couldn't find any other rocks in the vicinity where they covered the whole thing. (What I could see of this rock looked identical to the other rocks but apparently, to this lichen, it is better in some way than the others.)
