Ephebe lanata (L.) Vain.

Meddeland. Soc. Fauna Fl. Fenn., 14: 20, 1888. Basionym: Lichen lanatus L. - Sp. Pl., 2: 1155, 1753.
Synonyms: Conferva atrovirens Dillwyn; Ephebe intricata Lamy; Ephebe lapponica Nyl.; Ephebe pubescens auct. p.p.; Ephebeia cantabrica Nyl.; Ephebeia martindalei Nyl.; Parmelia lanata (L.) Nyl.
Distribution: N - Ven, TAA, Lomb (Vezda Lich. Rar. Exs. 357), Piem (Isocrono & al. 2004, 2006), VA (Valcuvia 2000), Emil (Tretiach & al. 2008, Fariselli & al. 2020). C - Tosc (Tretiach & al. 2008, Lastrucci & al. 2009), Sar (Nöske 2000).
Description: Thallus minutely filamentous, black, forming 2-3(-5) cm wide, irregular carpets, consisting of soft, coarse, cylindrical, irregularly branched, smooth, decumbent filaments. Filaments >50 μm thick, to 200 μm thick at base, usually without spine-like branches, dark-green to brown when wet, black and somewhat shiny when dry, without a cellular cortex, attached by a basal disc. Apothecia rare, inconspicuous, to 0.25 mm across, developing from pycnidia on swellings on the branches, with a punctiform, dark brown disc and an up to 40 μm wide thalline margin. Hymenium colourless, gelatinous, the upper part brown, I+ blue-green, K/I+ blue; paraphyses sparingly branched, the apices thickened; hypothecium colourless, dense. Asci 8.-spored, cylindrical-obclavate, thin-walled, with a K/I+ blue outer layer, without apical dome. Ascospores 1-celled (sometimes with 1-2 plasma bridges) hyaline, ellipsoid, 10-18(-20) × 3.5-6(-7) μm. Pycnidia rare, developing laterally from the filaments. Conidia hyaline, ellipsoid to bacilliform, 3-5 x 1-2 μm. Photobiont cyanobacterial (Stigonema); photobiont trichomes with true branchings, i.e. side branchlets formed by periclinal cell divisions in the photobiont trichome. Spot tests: all negative. Chemistry: without lichen substances.
Note: an arctic-alpine to boreal-montane, circumpolar lichen with outliers in the cool-temperate zone, found on steeply inclined, periodically wetted or inundated siliceous rocks, on seepage tracks, etc., with optimum above treeline
Growth form: Fruticose filamentous
Substrata: rocks
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly sexual
Periodically submerged (e.g. in creeks)
