general taxon notes:

 

Campylium consists of some 28 species worldwide, and nearly half of them are better understood (Crosby et al. 2000). Three species and one variety are recognized in China. The reports of C. amblystegioides Broth., C. courtoisii Paris & Broth., C. elodes (Lindb.) Kindb., and C. uninervium Müll. Hal. cannot be verified at this time.

6. Campylium (Sull.) Mitt.   细湿藓属   xi shi xian shu
J. Linn. Soc., Bot. 12: 631. 1869. Hypnum subgen. Campylium (Sull.) Waldh., Bull. Soc. Imp. Naturalistes Moscou 37(2): 37. 1864. Hypnum sect. Campylium Sull. in Gray, Manual (ed. 2) 677. 1856.
 
Plants minute to small, often slender, green or yellowish. Stems prostrate, irregularly or regularly branched; in cross section cortical cells in 1–2 layers, thick-walled; central strand weakly differentiated; pseudoparaphyllia small, foliose, lanceolate or triangular; rhizoids sometimes present on costae. Stem leaves erect or squarrose, 1.0–3.0 mm × 0.4–0.6 mm, gradually acuminate, from ovate-cordate or broadly triangular leaf base to a long apex, sometimes involute, squarrose or often reflexed at apex; margins plane, serrulate; costae single or forked, short or lacking; median leaf cells linear, 20–40 μm × 5–7 μm; alar cells often distinctly differentiated, hyaline, enlarged, rectangular. Autoicous. Inner perichaetial leaves lanceolate, plicate; costae single, strong, reaching 1/2 the leaf length. Setae reddish, elongate; capsules horizontal, ellipsoidal; mouth constricted when dry; exothecial cells quadrate to rectangular; exostome teeth cross-striate below, papillose above; cilia 1–4, as long as the segments, nodulose. Spores 10–24 mm in diameter, papillose.
