Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, forming orbicular to irregular, up to 1(-2) cm wide rosettes. Lobes discrete to partly imbricate, 0.3-0.5(-0.7) mm broad, usually flat, whitish grey to pale grey-brown, epruinose, with laminal, round, subcapitate soralia with farinose soredia. Lower surface white to tan, with simple rhizines. Upper and lower cortex paraplectenchymatous; medulla white. Apothecia rare, lecanorine, to 1.5 mm across, the thalline margin sometimes with a corona of rhizines. 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, 17-24 x 8-9 µm, Physcia-type. Pycnidia rare. Conidia ellipsoid. Photobiont chlorococcoid. Spot tests: all negative. Chemistry: without lichen substances.
Note: a mild-temperate species found on isolated trees with base-rich, soft bark; certainly more widespread albeit never common, perhaps often confused with stout specimens of Hyperphyscia adglutinata.
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)
