Identification: Umbilicaria with brown thallus and “angular (to star-shaped), immersed to sessile apothecia” (Hestmark in Nash, vol 2, 2004, p.549). Hestmark goes on to say that “Umbilicaria phaea is the most widespread rock tripe in the [Sonoran] area, something that reflects its ability to grow in very dry habitats.”
