Lichen-I like the colder colours being white and pale blue which then contrast with the warmer colours being the oranges. I could create this by ruffling up tissue paper which would look frilly a like the lichen.

caloplaca ignea with acarospora

Caloplaca ignea, the "flame lichen" (orange) with a species of yellow Acarospora ("cobblestone lichen" or "cracked lichen") or Pleopsidium on "tombstone slate" in the Sierra foothills, California


The larger crustose lichen is called Gray-orange Disk Lichen (Lecidia lapicida) and occurs on rock such as basalt and granite.
