By the toes, I’m guessing: tree frog. But I think of tree frogs as green—my ignorance, I’m sure (and the amphibian ID book is at our first home, not here). I can use that rural CYA naming strategy, and call it a toad-frog?
That’s lush for a lichen. If I form a band (ha!), I’m thinking Lush Lichen will be on the short list for a name. Along with Illusion of Symmetry.
