general taxon notes:
There are eight species of this genus in the world (Crosby et al. 2000). Pterobryon subarbuscula Broth. and P. subarbuscula var. longissima Nog. reported from Taiwan (Noguchi 1937; P.-C. Chen et al. 1978; Redfearn et al. 1996) cannot be confirmed. Only one species is known in China.

Plants usually robust, green, light yellowish, or yellowish brown, in dense tufts or mats. Primary stems prostrate, with dense, brownish rhizoids; secondary stems dendroid or pendulous, sparsely foliate, with squarrose leaves at the base, densely and irregularly pinnately branched above, often with erect-spreading branches and densely foliate, somewhat complanate, obtuse at branch tips. Leaves of upper secondary stems and mature branches erect-spreading, oblong-ovate or ovate-lanceolate, slightly concave, strongly plicate, shortly or long acuminate at the apex; margins usually serrate above; costae single, ending near the apex; leaf cells narrowly hexagonal to linear-rhomboidal or linear, moderately thick-walled, smooth, weakly porose; basal leaf cells lax, brown; alar cells more or less differentiated. Dioicous. Inner perichaetial leaves ovate-lanceolate, sheathing at the base, abruptly acute or narrowly long acuminate at the apex. Setae very short; capsules immersed, usually ovoid, brown; opercula low conic, with a short and straight beak; peristome double or sometimes with endostome poorly developed, rarely a prostome present; exostome teeth pale yellow, narrowly lanceolate, smooth, median line indistinctly zigzagged; endostome segments often attached to the teeth, thin, hyaline; basal membrane very low or absent; cilia absent. Calyptrae small, mitrate, smooth. Spores spherical, finely or densely papillose.
