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]
