This looks like a sterile crust. (I assume we’re talking about the orange thing.) I would guess Caloplaca. K test will verify the presence of anthraquinones (K+ deep wine red). Sterile crusts on rocks are poorly studied worldwide. We only just recently got a preliminary key to the North American species after decades of study. Caloplaca, on the other hand, is colorful enough that this might be described.
