Lovely pics — and I applaud your decision to let it be. Such little spots of magic are naturally bounded, not only in space, but in time as well.
BTM, lichens similar to your “rock tripe” are everywhere that I’ve been hiking in the Shenandoah area. It looks like the mountains have eczema. ;-) I’m pretty sure the rocks are providing them with not only a surface, but trace minerals as well.
