≡Collema cladodes Tuck., Gen. Lich.: 89 (1872).
Description : Thallus pulvinate or tufted, to 5 mm diam., at first a rosette of short, flattened squamules, that at length elongates into cylindrical, dichotomously or subdichotomously branching, minutely wrinkled lobes, 0.1–0.2 mm diam., and to 2 mm long, the lobe ends swelling to produce hormocystangia, 0.15–0.3 mm diam., that eventually rupture and become cup-like. Apothecia not seen.
S: Marlborough (Schoolhouse Bay, Queen Charlotte Sound), Canterbury (Cave Stream). On coastal rocks and inland on damp, limestone outcrops. Known also from Great Britain, Europe, Scandinavia and North America (Degelius 1945; Coppins et al. 1992a; Santesson 1993; Esslinger & Egan 1995; Scholz 2000; Schultz 2004b).
