  in A.Henssen, G.Vobis & B.Renner, Nordic J. Bot. 2: 595 (1982). T: L. Ianthe, c. 40 km south of Hokitika, Westland, South Island, New Zealand, 18 Sept. 1981, A.Henssen 27487a; holo: MB; iso: CHR, UPS.  
  Thallus fruticose, byssoid, whitish, forming spreading loosely attached colonies toc. 80 mm wide, composed of terete or partly flattened branched and densely entangled lobes, 0.2–0.4 (–0.8) mm wide, to 5 mm long. Hyphae 3.5–9.0 µm thick; lumen (0.5–) 1.0–2.0 µm wide. Photobiont cells (6–) 9–10 µm diam., aggregated in clusters near the surface of the lobes. Apothecia globose, immarginate, 0.3–0.4 mm diam., mostly pale pink, sometimes compound, ±stipitate, abundant at the tips or on the surface of the lobes. Epithecium pale yellow-brown, granular, colourless in KOH. Hymenium (25–) 30–40 µm thick, hyaline. Hypothecium hyaline, mostly 15–20 µm thick, sometimes elongated into a stipe. Asci cylindrical, (20–) 24–27 × 6.5–7.5 µm. Paraphyses c. 1.5 µm thick. Ascospores bacilliform, 5–7 × 1.0–1.5 µm, simple but sometimes with plasma bridges. Pycnidia predominantly at the tips of lobes, globose, 30–70 µm diam. Conidia bacilliform, 3.0–4.5 × 1.0 µm. CHEMISTRY: Thallus K–, KC–, C–, Pd+ red, UV+ rather weakly whitish; containing protocetraric and squamatic acids.
  An extremely rare species in Tas. where it occurs on moist, smooth-barked, shaded tree trunks in lowland, cool-temperate rainforest in the north-western, ‘Tarkine’ region. Also known from New Zealand.
