general taxon notes:
There are about 80 species of this genus in the world. Fourteen species are treated in this flora.

 

Untreated species and reports based on misidentifications:
 
Brachymenium pulchrum Hook. and Brachymenium radiculosum (Schwaegr.) Hampe, reported from Zhejiang province (R.-L. Hu & Y.-F. Wang 1981; Redfearn et al. 1996; Y.-F. Wang & Y.-Z. Tao 1992), were based on misidentified specimens. The specimens belong to Bryum billarderi Schwaegr. Brachymenium macrocarpum Card. was reported new to China in Guizhou Province (X.-Y. Wang & D.-X. Wang 2005), but we were unable to verify the voucher specimens. This species has been treated as synonym of Brachymenium klotzschii (Schwaegr.) Par. by Ochi (1980).

Sp. Musc. Frond., Suppl. 2: 131. 1823. Bryum sect. Brachymenium (Schwaegr.) C. Müll., Syn. Musc. Frond. 1: 242. 1848. Bryum subgen. Brachymenium (Schwaegr.) Mach., Cat. Descr. Briol. Portug. 81. 1919.
 
Plants small to rather large, pale green, yellowish green to brownish, in loose or dense tufts. Stems erect, with newly innovated branches often in equal lengths at base. Leaves usually crowded at branch apex, sparsely foliate below, ovate, ovate-lanceolate to ligulate, acuminate at apex; costae often strong, ending just below the apex or percurrent to excurrent; leaf cells hexagonal, rhomboidal or linear-rhomboidal; basal cells rectangular. Dioicous or autoicous. Setae elongate, erect or slightly curved; capsules mostly erect or inclined, rarely horizontal to pendulous, symmetric, pyriform, ovoid or club-shaped; neck more or less developed; stomata numerous; annuli differentiated; opercula small, conic, often apiculate; peristome double; exostome teeth lanceolate, brownish at base, hyaline above, papillose; endostome segments usually not well developed, keeled; basal membrane ca. 1/3–1/2 the height of teeth, more or less papillose; cilia mostly absent. Spores spherical, papillose.
