Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, closely adnate in the center, forming orbicular to more commonly irregular, 1-3 cm wide rosettes. Lobes grey to pale brown in sun-forms, (0.6-)1-1.5(-2) mm broad, dull to weakly shiny, epruinose, ascending at tips, with terminal, labriform soralia (laminal soralia often also present), the soredia often yellowish to reddish due to the exposed medulla, farinose, individual soredia mostly <40 µm in diam. Lower surface black, with abundant, black, simple rhizines. Upper cortex paraplectenchymatous, >22 µm thick; medulla yellow to orange-red in lower part, rarely white throughout; lower cortex paraplectenchymatous. Apothecia rare, lecanorine. 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, Physcia-type, 23-28 x 9-11 µm. Pycnidia rare. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; soralia and medulla often K+ red. Chemistry: medulla usually with skyrin, without fatty acids.
Note: a mild-temperate lichen found on epiphytic bryophytes and bark in open, humid woodlands; specimens without the red pigment in the medulla, which are not rare, can be easily confused with other species.
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)
