Lichenologist 39, 5 (2007).

Protolog: Thallus ut in Xanthoparmelia globulifera sed lobis et isidii differt. Superficies superior isidiata, isidiis globosis demum cylindribus, simplicibus demum coralloidibus. Superficies inferior brunnea, modice rhizinata, rhizinis simplicibus concoloribus. Thallus K-; medulla K, C, P-, UV-; acidum usnicum, acidum constipaticum et acidum protoconstipaticum continens.

Molecular barcode: Data lacking.

Thallus: foliose, adnate, 3-10 cm wide. Lobes subirregular, apically rotund, contiguous to sparingly imbricate, 1-2.5 mm wide. Upper surface yellow-green, emaculate, isidiate, soredia absent. Isidia moderately dense to dense, globose at first but then cylindrical, simple or rarely becoming coralloid, to 1 mm high, concolorous with the upper surface, apices blackened, syncorticate. Medulla white. Lower surface mid-brown to dark brown, but not blackened. Rhizines sparse to medium, simple, concolorous with the lower surface, to 1 mm long. Apothecia and pycnidia not seen (Pérez-Vargas et al. 2007: 446).

Photobiont: Data lacking.

Chemistry: Cortex K-, C-, KC-, yellow, P-, UV-; medulla K-, C-, KC-, P-, UV-; containing usnic acid, constipatic acid and protoconstipatic acid (Pérez-Vargas et al. 2007: 446).
