Endemic
Pertusaria circumcincta is a corticolous species (not saxicolous as indicated in Galloway (1985a: 372)), characterised by disc-like apothecia with margins often completely enclosing disc and with pale to dark red-brown discs that are thinly white-pruinose. It has 1-spored asci, the ascospores 100–160(–230) × 40–65(–74) μm, the wall 3–4 μm thick.
