Costa subpercurrent; in section subrounded, guide cells 2-3, small, ventral cells in single row, similar to guide cells, dorsal stereid band small, group of 6-8 cells, frequently with gap below guide cells, dorsal surface cells ± larger, thin-walled. Laminal cells rectangular to oblong-rhomboidal; upper marginal cells bulging; basal cells rectangular. Autoicous. Perichaetia terminal, leaves large, spathulate-acuminate, widespreading wet. Seta 0.5-0.7 mm long, yellowish; capsule exposed, erect, cleistocarpic, globose to elliptical, 1.0-1.2 mm long, smooth, reddish yellow; exothecial cells angular, subquadrate to hexagonal; stomata present at base of urn, phaneropore; calyptra swollen, completely enclosing capsule, mitrate-rostrate, 1.3 mm long; spores immature, rounded, 30 µm, hyaline, weakly papillose with distinct tetrad scar.
