Description: Thallus foliose, broad-lobed, heteromerous, dorsiventral, greenish grey to brownish when dry, blackish green when wet, forming 1-3(-5) cm wide rosettes or consisting of a few lobes only. Lobes 5-10 mm broad, rounded, concave, ear-shaped and sorediate when young, later ascending, esorediate and bearing vertically arranged apothecia. Soralia maculiform, laminar, flat, tending to disappear in fertile specimens (leaving discoloured patches), at first orbicular and 1-3(-5) mm across, then becoming confluent, with grey to grey-brown soredia. Upper surface tomentose, at least at margin; lower surface whitish, with narrow (0.4-0.7 mm broad) whitish to brownish veins and dense, up to 4 mm long rhizines becoming tufted and darkening. Upper cortex pseudoparenchymatous; medulla white; lower cortex absent. Apothecia rare in sorediate specimens, common in esorediate ones, saddle-shaped, brown, located at the tip of short ascending lobes. Paraphyses simple, distinctly thickened above. Asci fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores 3-5(-7)-septate, hyaline to pale brown at maturity, fusiform, (36-)45-65(-80) x 3-5 μm. Pycnidia rare, dark, immersed. Conidia fusiform. Photobiont cyanobacterial (Nostoc, the cells not in long chains). Spot tests: cortex and medulla K-, C-, KC-, P- (soralia very rarely faintly C+ and KC+ pink). Chemistry: without lichen substances, or occasionally with low amounts of gyrophoric acid and methyl gyrophorate in soralia.Note: a cool-temperate to boreal-montane, ephemeral lichen of disturbed mineral soil, most common in the Alps near and above treeline, becoming much rarer in Southern Italy.
Growth form: Foliose, broad lobed
Substrata: soil, terricolous mosses, and plant debris
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
