Characteristics

Plants small, erect, yellowish green; terricolous. Stems 2-5 mm high, simple; in section round, central strand present, inner cortical cells large, thin-walled, outer cortical cells in 2 rows, stereids. Leaves patent, lamina narrow, bistratose above; oval to ovate, 1.0-2.5 mm long; apex acuminate; margin plane, entire to serrulate at apex. Costa broad, occupying a third to half of leaf width, ending in acumen; in proximal section flattened, guide cells 10, exposed ventrally, large, incrassate, dorsal stereid band 1-2 cells thick, dorsal surface cells small, strongly incrassate; in distal section dorsal and ventral surface cells similar to laminal cells, incrassate, surrounding a single-layered median stereid band. Laminal cells rectangular or infrequently quadrate above, incrassate; basal cells larger, narrow-rectangular. Autoicous. Perichaetial leaves ovate-acuminate, 2.5-3.5 mm long. Seta 5-7 mm long, yellow, reddish with age; capsule erect, urn short-cylindrical, 1.0-1.5 mm long; peristome fragile, to 0.3 mm high, teeth irregularly thickened, deeply cleft, frequently with large perforations, papillose; operculum rostrate, 0.4 mm long; calyptra cucullate, 2.5 mm long; spores round, 14-18 µm, papillose.
