Camptochaete

Dioicous. Asexual propagules absent. Loose wefts on tree trunks, exposed roots, rocks or occasionally soil. Stems differentiated into creeping primary stems and erect-ascendant secondary stems, with dense or sparse ventral tufts of reddish-brown rhizoids in leaf axils where in contact with substrate; central strand indistinct or absent (not in Victoria) throughout stems, absent or rarely indistinct (not in Victoria) in branches; pseudoparaphyllia foliose; primary stems sparingly branched, pale brown; secondary stems differentiated into a basal stipe section and a regular or irregularly 1–3-pinnately branched frond section; branches nearly straight or rarely curved when dry, mostly complanate. Stipe and frond leaves differentiated, weakly to strongly concave; apex obtuse, acute or acuminate, sometimes mucronate; costae usually double in lower half or extending to 3/5 of leaf length (not in Victoria), or absent; margins entire or denticulate, plane or occasionally inflexed; mid-laminal cells linear, prorate, becoming shorter toward base and apex where rhomboid; alar cells weakly differentiated, shorter, more pigmented, sometimes forming a triangular group; stipe leaves oblong to obovate or orbicular, erect and imbricate or patent and well-separated; frond axis leaves obovate, ovate or orbicular, erect- to wide-spreading, sometimes imbricate, rarely falcate-secund, arranged around stem and facing all directions to complanate, wrinkled, striate or not altered when dry; branch leaves similar to frond-axis leaves but smaller. Capsule erect to horizontal, straight or curved, ellipsoid, oblong or cylindric, with a well-differentiated annulus. Calyptra cucullate, smooth, glabrous. Opercula conic to apiculate or rostrate from conic base. Exostome teeth with a distinct shoulder; endostome equal to or greater than exostome height, with a basal membrane c. ½ endostome height; cilia present.
