general taxon notes:

 

Campylopus is a large genus with a high degree of taxonomic complexity and worldwide distribution. It includes about 600 published species in the world. Seventeen species, one subspecies, and one variety are recognized for China in this treatment. Frahm’s revision of East-Asian species of Campylopus is useful in the study of Chinese taxa (Frahm 1992).

10. Campylopus Brid.   曲柄藓属  qu-bing xian shu
Muscol. Recent. Suppl. 4: 71. 1819.
 
Plants small, or medium to very robust, often coarse and rigid, yellowish brown to reddish brown, usually silky, in dense tufts. Stems erect, simple or branched by innovations, comose or somewhat equally foliate, often densely radiculose below; central strand present. Leaves erect or flexuose-spreading, lanceolate to ovate-lanceolate or ovate-subulate, usually gradually narrowed to a subtubulose acumen; margins often plane, sometimes incurved, variable serrate toward the apex, nearly always denticulate at the extreme apex; costa broad, often occupying ½ or more the leaf base width, filling most of the subula, percurrent to long-excurrent, or in a hyaline hairpoint, often ribbed or denticulate at back above, sometimes with multi-celled lamellae, with either two stereid bands or a single (dorsal) stereid band, rarely without stereid cells in transverse section; upper cells quadrate to elongate-rhomboidal or rectangular, incrassate, smooth; lower cells short-rectangular to rhomboidal or linear, firm-walled, rarely porose, narrower toward the margins, sometimes forming a hyaline border; alar cells usually well marked, forming auricles, inflated, extending to the costa, hyaline or reddish brown. Dioicous. Perichaetial leaves usually enlarged, with wider basal portion and narrower costa. Setae elongate, usually cygneous, sometimes erect-flexuose when moist; capsules erect or curved, ovoid to ellipsoid, usually furrowed when dry, sometimes strumose; stomata absent; opercula rostrate; annuli present, often compound in 2-3 rows of larger cells, deciduous; peristome teeth 16, divided to the middle or little more, orange-brown and vertically striate below, hyaline and papillose above. Calyptrae cucullate, often fringed at base. Spores spherical, variously papillose, yellow to brown.
