Synalissina intricata (Arnold) Nyl.

in Hue, Rev. Bot. Bull. Mens. 4, 1885–1886: 349, 1886.. Basionym: Omphalaria intricata Arnold - Flora, 52: 254, 1869.
Synonyms: Leciophysma fennicum Räsänen; Lempholemma fennicum (Räsänen) Degel.; Lempholemma intricatum (Arnold) Zahlbr.; Synalissa intricata (Arnold) Nyl.
Distribution: N - Frl (Henssen & Tretiach 1995), Ven (Nascimbene & al. 2021), TAA (Nascimbene & al. 2022).
Description: Thallus small-fruticose, filamentous, homoiomerous, gelatinous when wet, dark brown to almost black, sometimes grey-pruinose, consisting of up to 0.2 mm thick and up to 5 mm long, furcate, adpressed, entangled, longitudinally weakly wrinkled branches, forming up to 3 cm wide, small carpets or loose, flattened cushions. Apothecia rare, zeorine, laminal, globose, semi-immersed, up to 0.2 mm across, with a brown, finally convex disc, a thick thalline margin and a pale, thin proper margin, developing from ascogones arising in a spheroid tangle of generative hyphae. Proper exciple very thin, of parallel hyphae; epithecium brownish; hymenium and hypothecium colourless, the hymenial gel I+ reddish, K/I+ blue; paraphyses mostly simple, not apically thickened, coherent. Asci 8-spored, broadly clavate, thin-walled, with a distinct amyloid outer cap, but no apical dome, Peccania-type. Ascospores 1-celled, hyaline, subglobose to broadly ellipsoid, 10-14 x 8-11 μm, with a gelatinous perispore which dissolves in K. Pycnidia dark, immersed, pyriform. Conidia acrogenous, bacilliform or fusiform, 4-5 x 1-1.5 μm. Photobiont cyanobacterial (Nostoc, the individual cells 4-5 μm wide, arranged in short chains). Spot tests: all negative. Chemistry: without lichen substances.
Note: on steeply inclined surfaces of calcareous or basic siliceous rocks in seepage tracks, mostly in humid areas, perhaps more widespread in the Alps.
Growth form: Fruticose

Substrata: rocks
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)
On otherwise dry surfaces with short periods of water seepage after rain
