Rhynchostegium laxatum
(Mitt.) ParisInterwoven mats on tree trunks, shrub stems, logs or occasionally soil. Stems decumbent, c. 20–50 mm long, irregularly to subpinnately branched, with ascending short branches, with fascicles of brown rhizoids on ventral surface, central strand present. Stem and branch leaves differentiated by shape, erect to spreading when moist, erect and ±striolate when dry; costae single or rarely slightly forked, extending (1/3–) 1/2–2/3 leaf length, not ending in an abaxial spine; margins entire or denticulate toward apices, plane; cells linear-rhombic, 38–96 (–113.5) μm long, 6–12.5 μm wide, shorter at base, smooth; alar cells slightly inflated or subquadrate, in a poorly differentiated group. Stem leaves broadly ovate to oblong-ovate, 1.4–1.9 mm long, 0.6–1 mm wide, weakly concave; apices acuminate or filiform. Branch leaves ovate, mostly 1.2–1.6 (–1.8) mm long, 0.4–0.55 (–0.65) mm wide; apices acuminate. Setae 10–15 mm long, red-brown, smooth. Capsules inclined, oblong-cylindric, slightly curved, 1.4–1.8 mm long. Operculum rostrate from conic base, c. 1 mm long.
