Characteristics

Plants small, loosely caespitose, green to yellow-green; terricolous. Stems 2-4(-8) mm long, simple; in section round, central strand present, inner cortical cells in 3-4 rows, thin-walled, outer cortical cells in 2 rows, smaller, incrassate. Leaves flexuose above base when dry, erect-spreading wet; abruptly subulate above broad, oblong to obovate or occasionally oval base, (2-)4-6 mm long; apex weakly toothed; base sheathing; margins plane, entire; in section lamina unistratose. Costa filling subula, dorsal and ventral superficial cells rectangular, smooth; in proximal section concave, guide cells 8, exposed laterally, ventral stereid band small, ventral surface cells small, incrassate, dorsal stereid band 4-5 cells thick, dorsal surface cells substereids, smooth; in distal section ventral stereid band small, ventral surface cells incrassate, dorsal stereid band 2-3 cells thick, occasionally some cells not stereids, dorsal surface cells incrassate, smooth. Laminal cells rectangular, incrassate, smooth; basal cells rectangular to rhomboidal, thin-walled. Perichaetia terminal, leaves to 6 mm long, sheathing bases elongate. Seta erect, to 5 mm long, yellowish to red-yellow; capsules short-cylindrical, 1.5 mm long, weakly plicate dry, red-brown; exothecial cells rectangular, incrassate, quadrate to hexagonal at mouth; peristome erect, teeth triangular, 0.3 mm long, cleft to middle, vertically striate below, red-yellow, papillose and hyaline above; operculum long-rostrate, 1.1 mm long, cells not twisted; spores round, 30 µm, papillose, yellow-brown.
