Characteristics

Plants medium-sized to large, forming turfs, light green to dark green; saxicolous or terricolous. Stems suberect, 10-30 mm long, branching sparse, irregular; in section round, central strand small, inner cortical cells thin-walled, hyaline, in 3 or 4 rows, outer cortical cells somewhat thick-walled, yellow to red, in 3 rows. Leaves evenly spaced, larger above, spreading wet, appressed dry, ± flattened into one plane; somewhat asymmetrical, broadly ovate to elliptical or broadly spathulate, largest leaves 3-6 mm long; rounded and apiculate; strongly narrowed to insertion; margins plane, serrate to denticulate above midleaf; bordered by elongated, thickened cells, unistratose. Costa short and double or single and bifurcate, ending in lower leaf, smooth; in section elliptical, cells small, thickened. Upper laminal cells homogeneous, hexagonal to rhomboidal, 100-112 µm long, 50-56 µm wide, walls thickened, pitted, smooth; basal cells rhomboidal, greenish, walls thickened, pitted, smooth; alar cells not differentiated. Dioicous. Perigonia not seen. Perichaetia small, green; perichaetial leaves ovate-acuminate but with some leaves truncate, 1-2 mm long, leaf cells rectangular to rhombic or fusiform. Seta to 10 mm long, yellow-brown, roughly papillose throughout. Capsule exserted, inclined to nodding, weakly pyriform, 1.8-2.5 mm long, smooth, red brown; urn ovoid; neck differentiated, shorter than urn, curved; exothecial cells rounded to quadrate, walls thickened, collenchymatous, cells at mouth quadrate, neck cells irregular, quadrate to rectangular, stomata not seen. Peristome double, yellow; exostome teeth triangular, reflexed dry, inflexed wet, striate below with obvious zigzag line, papillose above, 400 µm high; endostome segments lanceolate above high basal membrane, keeled, as long as teeth, weakly granulate; cilia single, broad, almost as long as segments, weakly granulate. Operculum convex-rostrate, 0.5 mm long. Calyptra cucullate, rough when young. Spores rounded, 12-17 µm, weakly granulate, yellow-brown.
