If in a shady forest…

I’d probably call it Porpidia albocaerulescens. It is an extremely variable species. But there are few other easter crusts which agressively cover shaded forest boulders where nothing else will grow. This looks a bit like the “weathered” or “exposed” form. (It takes on a distinctive bluish tone when moist and deeply shaded, although it can also have orangish or brownish or yellowish tints.)
