Characteristics

Plants small to large, scattered, gregarious, green to grey-green; terricolous, saxicolous or corticolous. Primary stems long-creeping, frequently tomentose; secondary stem erect, 20-40 mm long; branching regular, flabellate above stipe; in section round, central strand large, inner cortical cells thin-walled, large, hyaline, in 5 or 6 rows, outer cortical cells smaller, weakly thick-walled, in 2 or 3 rows, epidermis of enlarged thin-walled cells, hyaline. Leaves dimorphic, flattened, widespreading wet, spreading and weakly crisped dry; stem leaves asymmetrical, broadly ovate in lateral ranks, 1.8-2.2 mm long; obtuse and apiculate or cuspidate; rounded at base; margins plane, entire, unistratose, bordered by elongated cells, hyaline; amphigastria orbicular or broader than long, 1.0-1.2 mm long; branch leaves asymmetrical, broadly ovate, 1.2-1.5 mm long; obtuse and apiculate or cuspidate; rounded at base; margins plane, serrate, unistratose, bordered by elongated cells, hyaline; branch amphigastria orbicular, to 1 mm long, margins entire. Costa variable, single, short or extending to midleaf, sometimes extending to apex, frequently forked, displaced proximally in lateral leaves; ventral and dorsal surfaces smooth, cells elongate; in section flattened, 3 rows of small, unthickened cells. Upper laminal cells rhomboidal, homogeneous, 45-75 µm long, 20-30 µm wide, walls thin, weakly pitted, smooth; basal cells not differentiated or some rectangular cells at attachment, walls thin, weakly pitted, smooth; alar cells not differentiated. Autoicous. Perigonia on stem, gemmate; perigonial leaves ovate-acuminate, 1.5 mm long. Perichaetia obvious, green; perichaetial leaves ovate to oblong, 1.5-2.0 mm long; acuminate; leaf cells fusiform, pitted. Seta 8-10 mm long, brown, smooth. Capsule exserted, horizontal to nodding, short-cylindrical, 1.5 mm long, smooth, brown; neck shorter than urn; exothecial cells quadrate to hexagonal, walls thin, cells at mouth quadrate, neck cells quadrate, annulus present; stomata raised, phaneropore. Peristome double, yellow; exostome teeth fragile, oblong, weakly striate, with median zigzag line, 350 µm high (old and broken); endostome segments linear above low basal membrane, shorter than teeth, smooth; cilia 1-3, shorter than segments. Operculum long-rostrate, 1 mm long. Calyptra cucullate, smooth. Spores rounded, 10-15 µm, granulate, yellowish.
