Leptogium hildenbrandii (Garov.) Nyl.

Act. Soc. Linn. Bordeaux, 21: 272, 1856. Basionym: Collema hildenbrandii Garov. - Lich. Prov. Comen., 1: 3, 1837.
Synonyms: Leptogium saturninum var. complicatum Anzi
Description: Thallus foliose, broad-lobed, homoiomerous, gelatinous when wet, firm and markedly rigid when dry, rather loosely adnate, forming large, more or less regular, 5-10(-13) cm wide rosettes. Lobes 5-10(-12) mm wide, 245-325 μm thick, contiguous or more or less imbricate, with rounded, ear-like apices, 70-150 µm thick. Upper surface brown-black or dark lead-grey, greenish brown when moist, minutely and irregularly but conspicuously wrinkled and striate. Lower surface white-tomentose, with 60-120 μm long hairs of cylindrical cells measuring 8-15 x 3-5 μm, and tufts of pale hapters. Upper and lower cortex formed by a single layer of 6-9 μm wide, angular cells, inner part of thallus with loosely interwoven chains of Nostoc and hyphae. Apothecia usually abundant, especially in the central parts, lecanorine, laminal, at first immersed in the thallus, then sessile and constricvted at base, 2-4(-6) mm across, with a brown-red, shiny disc and a grey-brown, rather thin, usually rugose thalline margin. Exciple euparaplectenchymatous; epithecium pale brown; hymenium colourless, I+ blue; paraphyses simple, 1-2.5 µm thick at mid-level, the apical cells slightly swollen; hypothecium colourless or pale yellow. Asci 8-spored, cylindrical-clavate, the apex strongly thickened, the apical dome K/I+ pale blue, with a downwardly projecting K/I+ deep blue tubular structure. Ascospores submuriform, hyaline, ellipsoid, 16-24(-26) x 8-10 µm. Pycnidia immersed, marginal to submarginal, 0.1-0.3 mm across. Conidia bacilliform, with swollen apices, 4.3-5.5 x 1.3-1.6 µm. Photobiont cyanobacterial (Nostoc, the cells in long chains of 12-16). Spot tests: all negative. Chemistry: without lichen substances.
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
