general taxon notes:
Palamocladium consists of three or four species in the world (Crosby et al. 2000). Two species were treated in China by R.-L. Hu and Y.-F. Wang (2005), including the East Asian species, P. nilgheriense (Mont.) Müll. Hal. In this flora, the treatment of Hofmann (1997) is followed. Palamocladium nilgheriense is reduced to a synonym of P. leskeoides (Hook.) E. Britton, which is a widely distributed species.

Plants medium-sized to rather robust, somewhat stiff, green, yellowish green, or brownish, glossy, in loose mats. Stems prostrate, radiculose or stoloniform, subpinnately branched; branches ascending or curved; central strand present. Stem and branch leaves similar, erect-spreading, often secund when dry, lanceolate to ovate-lanceolate or somewhat triangular-lanceolate, plicate, slenderly acuminate toward apex; margins usually sharply serrate nearly throughout to the base; costae single, nearly percurrent; median leaf cells elongate-elliptical or linear, thick-walled, often porose; alar cells small, quadrate, differentiated in a small group. Dioicous. Perichaetial leaves lanceolate, gradually or abruptly acuminate. Setae elongate, reddish, smooth; capsules erect, symmetric, elongate-ellipsoidal to shortly cylindrical, with short necks; opercula long conic-rostrate; annuli developed; peristome double; exostome teeth lanceolate, papillose throughout, cross-striolate at base; endostome segments linear, keeled, papillose; basal membrane high; cilia present, reduced or absent. Calyptrae cucullate, smooth. Spores spherical, finely papillose.
