Small, brown, umbilicate lichen, on dry exposed rocks. Apothecia immersed, black, angular. Underside coarsely papillate underside, with few if any rhizomorphs, generally dark. Medulla C+ and KC+ red.
Western North and South America.
On siliceous rocks, in very exposed dry areas.
The only other brown apotheciate Umbilicaria in the desert southwest of North America are:
U. hyperborea: apothecia circular and raised
U. angulata: rhizomorphs present underneath
U. torrefacta: thallus conspicuously perforated (hold up to light!)
U. muhlenbergii: circular apothecia in depressions, with rhizomorphs
Umbilicaria phaea is a brown, umbilicate foliose lichen that grows up to 6 cm (2.4 in) in diameter, sometimes in colonies covering large patches of desert rocks.[1]: 127 [2] One variety that grows in northern California is brilliant red.[1] It is (monophyllous) with a single 1 – 5 cm flattish leaf-like cap on top of an anchoring stem (umbilicate).[2] The leaflike top is smooth with some lobes, roughly circular, thin, and brittle.[2] The lower surface is light gray to light brown.[2] It has up to 2.5 mm black circular to slightly polygonal spots that are the fruiting bodies (apothecia), slightly sunken into the main nonfruiting body part (thallus).[2] It grows on siliceous boulders in very dry climates of western North and South America, where it is usually the most common member of its genus.[2]
