Seen to yellow-green above, reddish brown below; saxicolous. Stems erect, 20-30 mm tall, irregularly branched above, lower stems covered with reddish tomentum, radicles papillose with numerous large, high papillae; in section distinctly three-sided, subtriangular, central strand very small, inner cortical cells in 6-8 rows, large, thin-walled, reddish, outer cortical cells in 2 rows, stereids, reddish yellow, epidermal cells differentiated, thin-walled, fragile, quickly eroded. Leaves erect and weakly flexuose dry, erect-spreading wet; narrowly lanceolate, 2-4 mm long; apex acuminate; margins recurved from base to upper leaf, entire below, sharply serrate above, frequently doubly serrate. Costa percurrent, superficial cells long-rectangular, papillose; in section bulging dorsally, subround, guide cells 2-4, large, thickened, ventral cells in single layer, smaller than guide cells, thickened, dorsal substereid band 4 cells thick, dorsal surface cells not differentiated. Upper laminal cells rectangular, 4-6:1, thickened, minutely verruculose-striolate, as numerous low, short ridges, occasionally a few cells also prorate distally; basal cells slightly longer rectangular, minutely verruculose-striolate; alar cells not differentiated. Perichaetia terminal, leaves similar to vegetative leaves; basal leaf cells long-rectangular to linear, smooth, yellowish. Seta 8-12 mm long, reddish yellow; capsule weakly inclined, urn globose, 2.0-2.5 mm long, weakly striate dry, reddish yellow, mouth frequently oblique; exothecial cells large, hexagonal to rectangular or quadrate, thin-walled; stomata present at base of urn, phaneropore to subphaneropore; peristome double, exostome teeth 16, narrowly triangular, 0.3 mm high, papillose, with median zig-zag line, trabeculae strong, endostome segments 16, fragile above, finely papillose; operculum plano-convex; calyptra cucullate; spores subround to ovoid, 15-27 µm, warty, yellow-brown.
