Description: Thallus foliose, homoiomerous, markedly gelatinous when wet, 3-10 cm diam., lobed. Lobes to 1 cm wide, ear-like, c. 0.15 mm thick when dry, to 0.5 mm thick when wet, brown-black to dark olive-green, the surface finely striated (when dry), covered with crowded, globose isidia (0.2-0.8 mm diam. when wet). Lower surface grey, without rhizines or hairs. Upper and lower cortices absent. Apothecia rare, lecanorine, 2-3 mm across, with a brown-red, concave to plane disc and an isidiate thalline margin. Asci 8-spored, narrowly clavate, the apex thick, with a I+ blue apical dome and a I+ blue annulus projecting downwardly. Ascospores submuriform, ellipsoid to oval, 25-36 x 8-13 µm. Pycnidia rare, mostly marginal, pale. Conidia bacilliform simple, 4-5 x 1-2 µm. Photobiont cyanobacterial (Nostoc), in long chains. Spot tests: all negative. Chemistry: without lichen substances.
Note: a temperate to southern boreal-montane, holarctic lichen found on calcicolous mosses, rarely directly on rock in sheltered situations, e.g. in woodlands or on shaded walls; usually absent above treeline and rare within settlements and in areas with intensive agriculture.
Growth form: Foliose, broad lobed
Substrata: rocks
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
