Plants small, scattered, gregarious, light green, ± shiny; terricolous. Stems (0.5-)2-3 mm long, occasionally elongated with a few branches; in section round, central strand collapsed, dark brown, cortical cells in 3-4 rows, little differentiated or outer row ± larger. Leaves weakly contorted dry, spreading wet; narrowly spathulate, 1-2(-3) mm long, apex abruptly acuminate; base oblong; margins plane, strongly serrate above base by projecting cell ends. Costa weak, ending below apex or extending into acumen; in section bulging dorsally, guide cells 2, ventral cells 2, in single layer, similar to guide cells, dorsal stereid band small, consisting of 2-4 cells, dorsal surface cells smaller than guide cells, thickened. Laminal cells lax, rectangular to rhomboidal, mostly 2-3:1; basal cells rectangular, thin-walled. Perichaetial leaves slightly larger, not distinct. Seta erect, 0.4-0.6 mm long, yellowish to yellow-brown; capsule immersed, urn hemispherical, 0.5-0.6 mm long, smooth, yellow-brown, neck absent; exothecial cells lax, transversely rectangular to rhomboidal, 4 rows at mouth abruptly narrower and transversely rectangular; stomata present at extreme base of urn, phaneropore; annulus absent; peristome absent; operculum convex-apiculate, cells not twisted; spores subround to angular, 30-37 µm, light brown, papillose to strongly papillose.
