Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, forming irregular to orbicular, up to 3 cm wide, often confluent rosettes. Lobes discrete to partly imbricate, 0.5-1(-1.5) mm broad, usually flat, grey to brown, with sparse to numerous, multicellular, transparent cortical hairs near the lobe ends, epruinose, with terminal, labriform soralia. Lower surface black, with simple rhizines. Upper and lower cortex paraplectenchymatous; medulla white. Apothecia rare, lecanorine, to 2 mm across, the thalline margin with cortical hairs. Epithecium brown; hymenium and hypothecium colourless; paraphyses slender, often forked in upper part, the apical cells clavate, with a thin dark cap. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, ellipsoid, 18-25(-28) x 7-12(-14) µm. Pycnidia rare, immersed. Conidia ellipsoid. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mainly temperate lichen found on isolated trees, more rarely on rock; most common in Tyrrhenian Italy. Some older records could refer to P. cernohorskyi.
Growth form: Foliose, narrow lobed
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
