Description: Thallus foliose, strongly swollen and gelatinous when wet, loosely attached, isidiate, blue-grey to lead-grey when dry, dark green-grey when wet, 3-5 cm wide. Lobes poorly differentiated, markedly wrinkled and radially ridged, sometimes fenestrate, with dark grey to brown-black (darker than thallus), granular to subcylindrical isidia developing along the margins and on the ridges, finally spreading through the entire surface; lower surface paler, without tomentum. Upper and lower cortices composed of a single layer of angular cells; inner part of thallus with loosely interwoven chains of Nostoc and hyphae. Apothecia extremely rare (never observed in Italian material). Photobiont cyanobacterial (Nostoc, the cells in long chains). Spot tests: all negative. Chemistry: without lichen substances.Note: a mild-temperate to humid subtropical, typically western-Tyrrhenian species in Italy, most frequent in open, humid woodlands, especially in old coastal plantations of Olea.
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
