Ctenidium pubescens

Dioicous. Smooth mats on rocks, tree bases and logs, rarely on soil, pale green to yellowish green. Stems 2–8 cm long, creeping, regularly to irregularly pinnately branched, dark brown, with fascicles of red-brown rhizoids, with branches 0.5–1 cm long. Stem leaves ovate- to triangular-lanceolate, 1.4–1.6 mm long, 0.5–0.6 mm wide, erect-spreading, arranged around stem and facing all directions, falcate-secund or weakly complanate; base cordate; apices acuminate, often twisted; costa short and double, faint, extending to ¼ of leaf length; margins serrulate or serrate, weakly undulate, slightly recurved near base, otherwise plane; laminal cells linear, 50–70 (–80) μm long, 3–6 μm wide, prorulate or prorate. Stem leaves usually rigidly spreading, sometimes secund and decurved, 1.4 mm long, to 0.75 mm wide, mostly longitudinally striate when dry, sometimes transversely undulate; alar cells shorter and wider, forming a large group in stem leaves. Branch leaves narrowly ovate-lanceolate, erect-spreading, complanate, 0.8–1.2 mm long, 0.25–0.4 mm wide, concave; alar cells scarcely differentiated. Setae 10–15 mm long, reddish brown, almost smooth. Capsules inclined to horizontal, narrowly ellipsoid, 1–1.5 mm long. Opercula shortly rostrate or conic, c. 1–1.5 mm long.
