Biogeography: Continent: Africa, Antarctica, Asia-Temperate, Australasia, Europe, Northern America, Southern America, Pacific, and Asia-Tropical. Checklist records: Australia, Austria, Germany, Great Britain, Guianas, Italy, New Guinea, New Zealand, Sonoran Desert, Sweden and Norway, Thailand, and United States and Canada (continental).

Ecology: Lignicolous.

Thallus: Continuous throughout, dispersed along the periphery, continuous in the centre, or dispersed throughout and distinctly seperate; lobes elongate, lunate, linear, or flabellate, horizontal, ascending, or imbricate; angular or rounded at the front; separate thallus parts (0)-0-0-0-(0) mm wide. Thallus Size and Differentiation: (0)-0-0-0-(0) cm in diameter. Thallus Outline: Margin crenate. Upper Surface: Grey-brown or brownish red; pruina scarce or abundant; continuous or patchy; without hairs or hairy; hairs apical or interspersed; isidiate; isidia laminal, submarginal or marginal, isolated or clustered; with isidiomorphs; soralia grey, brown, grey-brown, brownish yellow, yellow, or olive, central, laminal, subperipheral, or peripheral, lateral, subapical, or terminal, eroding from the tip of tubercles, semicapitate, capitate, labriform, helmet-shaped, or ear-shaped, erose, punctiform, or linear, prominent, slightly excavated or fully excavated, isidiate, soredia coarse or farinose; blastidiate. Lower Surface: Black, grey, brown, or white in the centre, black, grey, brown, white, or pale brown along the margin; rhizines white, grey, or black, not branched or branched, irregularly branched, dichotomously branched, squarrosely branched, or sparsely furcate.

Upper Cortex: Outer cortical layer prosoplectenchymatous, paraplectenchymatous, or scleroplectenchymatous. Medulla: White, yellow, orange, or red.

Ascocarps: Forming in the thallus centre, all across the thallus surface, close to the margin, not the thallus centre, or directly at the thallus margin, (0)-(0) per thallus, (0)-0-0-0-(0) mm in diam.. Margin: Smooth; sorediate; not isidiate or isidiate.

Ascospores: (0)-0-0-0-(0) µm long, (0)-0-0-0-(0) µm wide.

Secondary Metabolites: Not detected or present; only in the upper part of the cortex, throughout the thallus medulla, or in soredia (or soralia), scabrosin 4,4'-diacetate, scabrosin 4,4'-dibutyrate, scabrosin 4-acetate-4'-butyrate, scabrosin 4-acetate-4'-hexanoate, secalonic acid a, and variolaric acid.

Spot Tests: Absent or present reactions. Cortex: KC –, + deep yellow, or + bright yellow (citrine, lemon), –, + deep yellow, or + bright yellow (citrine, lemon); medulla: K –, + yellow, + bright yellow (citrine, lemon), or + orange; KC –, + yellow, + bright yellow (citrine, lemon), or + orange; soredia: K –, + deep yellow, + pink, or + orange; KC –, + deep yellow, + pink, or + orange.
