Checklist records: Australia, Chile, Japan, Mexico, Peru, Sonoran Desert, United States and Canada (continental), and Venezuela.

Ecology: Biotroph; lichenized; corticolous; substrate non-calciferous.

Thallus: Foliose, subdivided into main parts, and secondary or without secondary parts, sub irregular, continuous throughout, lobed; lobes elongate, horizontal; plane; branches applanate (moderately flattened); bifacial; not segmented. Thallus Size and Differentiation: 4-8-12 cm in diameter; main branches basally not constricted; apex rounded. Upper Surface: Pale grey, plane, matt, smooth; not fissurate; not foveate; not convoluted; immaculate; without patches; epruinose; not pseudocyphellate; not wrinkled; eciliate; without hairs; not isidate; without isidiomorphs; not papillate, pustulate, pustules regular; sorediate; soralia white, laminal, erupting from pustules, capitate, punctiform, slightly excavated, isolated, not confluent with other soralia, emarginate, soredia farinose; not tuberculate; not lobulate. Lower Surface: Present, black, black in the centre, brown along the margin; attached by holdfasts; not cyphellate; not wrinkled; rhizinate; rhizines moderately abundant, with a broad non-rhizinate margin, black, not branched; not tuberculate.

Hydrochasic Thallus Movement: Not performing hygrochasic thallus movement.

Upper Cortex: Double-layered.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming all across the thallus surface, all across the surface, sparse, 2-3.5-5 mm in diam.. Margin: Crenulate, epruinose; not sorediate; not isidiate; without pseudocyphellae pseudocyphellae; not ciliate; not hirsute. Disk: Brown.
