19. Kiaeria I. Hagen, Kongel. Norske Vidensk. Selsk. Skr. (Trondheim). 1914(1): 109. 1915.

Plants minute to large, green or yellowish, in dense or sparsely radiculose tufts. Stems erect or ascending, simple or 2–3-branched; central strand absent. Leaves lanceolate from narrowly ovate base, gradually subulate to subtubulose apex, falcate-secund or flexuose or crispate when dry, erect-spreading when moist; margins plane, entire or serrulate at the apex; costa narrow, percurrent to excurrent, with stereid cells and median guide cells poorly differentiated; upper cells subquadrate to linear, smooth or slightly mammillose; lower cells elongate-rectangular, sometimes porose; alar cells not or weakly differentiated. Autoicous or polygamous. Perigonia sessile or terminal on branches. Perichaetial leaves larger and sheathing at base. Setae straight, elongate, reddish brownish; capsules ovoid to shortly cylindric, suberect to inclined, somewhat curved, usually strumose, smooth or somewhat furrowed when dry; opercula small, obliquely rostrate; annuli simple, persistent or compound, deciduous; peristome teeth 16, divided or perforated down to the middle, yellowish, papillose above, vertically striate, reddish brown below. Calyptrae not seen. Spores spherical, brownish, finely papillose.
