Recognized by sight: Bloody comma lichen
This is a very variable but distinctive species. Identifiable by thalli colors and growth pattern. Seldom seen far from the coast and a good one to learn. Feel free to look up info on it. The other red tree lichens in CA have very different structures, mostly caloplaca-like.
Used references: California Lichens

Not sure what this is

But you can rule out Herpothallon / Cryptothecia because it doesn’t have a thick fluffy noncorticate thallus. This looks more like a Pyrenula or maybe Arthonia (Arthothelium?) to me.
