Protologue: Planta saxicola. Thallus fruticosus, uniformis, viridulo-griseus vel albido-griseus, pendulus vel suberectus, albido-grisei pruinosus, ramosus; rami primati applanati, superficierum reticulati, ca. 2-3.5 x 0.1-1.2 cm; rami terminales cylindricei, ca. 0.1-0.2 mm in diametro. Cortex usque ad 35 µm crassus, hyalinus, hyphis periclinalis. Medulla luteola, inconspicua, coalescens. Stratum algarum discontinuum. Alga ad genus Trenepohlia pertinens. Soredia et isidia nulla. Ascomata et pycnidia incognita. Thallus acidum gyrophoricum, lecanorinum et orsellinum continens.

ITS barcode: Data lacking.

Description: Lichen. Thallus fruticose, greenish grey to whitish grey, pendant to suberect, whitish grey pruinose, branched; main branches prominent, flat, with a reticulate surface, ca. 2-3.5 x 0.1-1.2 cm; terminal branches terete; ca. 0.1-0.2 mm in diam. Cortex with periclinally arranged hyphae, hyaline, up to 35 µm thick. Medulla yellowish, inconspicuous, coalescent, sometimes not distinguishable from the cortex (=Darbishirella type). Algal layer discontinuous. Soredia or isidia absent. Ascomata or pycnidia unknown.

Photobiont: Belonging to the genus Trentepohlia (Feige & Lumbsch 1993: 383).

Chemistry: Gyrophoric acid (major), lecanoric acid (minor), orcellinic acid (trace) (Feige & Lumbsch 1993: 383 by HPLC and TLC).

Ecology: Saxicolous, on exposed calcareous cliffs in coastal areas, mainly in small caves in therock in somewhat shady places (Feige & Lumbsch 1993: 383).

Distribution type: Corse (France), Sardinia (Italy), Sicily: Aegadian Islands (Italy), Mallorca, Menorca (Baleares, Spain), Almeria (Spain), Saria island (Greece), Morocco.

Taxonomy: The species resembles morphologically a poorly developed Roccella species, but it can readily be distinguished by the presence of gyrophoric acid and the different anatomy of the thalli (Feige & Lumbsch 1993: 383).

Note: When Ingaderia troglodytica was described, the species was simultaneously recorded from Sardinia (Italy), Lampedusa (Italy), Almeria (Spain) and Morocco by the authors.
