Trichosteleum

Autoicous. Asexual reproduction occasionally by filamentous gemmae in leaf axils or along stems. Tufts or mats on logs and trees. Stems creeping, irregularly branched, with fascicles of rhizoids on main stem; pseudoparaphyllia foliose. Stem and branch leaves similar, ovate, oblong-lanceolate or elliptic-lanceolate to lanceolate, sometimes falcate, arranged around the stem and facing all directions, slightly secund or complanate, erect-spreading when moist or dry; costa absent or short and double (not in Victoria); apex obtuse (not in Victoria), acute (not in Victoria) or acuminate, without a hairpoint; margins entire or serrulate (not in Victoria) near base, often serrulate or sometimes serrate (not in Victoria) near apex, plane or occasionally recurved, without a border; laminal cells linear to oblong or rhomboid, oblong near apex, unipapillose, at least in apical 65–75% of leaf, sometimes almost smooth throughout; alar cells clearly differentiated, greatly inflated, oblong or subquadrate and sometimes coloured in a basal row, sometimes also with a few non-inflated subquadrate or irregular cells apical to basal row. Capsules erect to pendent, asymmetric, ovoid to cylindric, without an annulus. Calyptra cucullate, smooth or roughened near apex, glabrous. Operculum rostrate. Peristome double; endostome segments incurved when dry, c. 2/3 of exostome teeth to same length as exostome teeth, with a high basal membrane; cilia present.
