Plants small to medium-sized, loosely caespitose to caespitose, yellowish green to brown; terricolous or corticolous. Stems up to 25 mm tall, branching by innovations, tomentose below; rhizoids smooth to papillose or granulose, reddish brown or reddish; in section subpentagonal or round, central strand absent, inner cortex 5-10 cells across, thin-walled to incrassate, outer cortical cells smaller, in 1-3 rows, incrassate or with substereids to stereids, outer cells frequently rough. Leaves ± crowded, ± equal in size or larger above, twisted or secund and ± appressed when dry, erect-spreading to squarrose and recurved when wet; narrowly oblong-lanceolate to lanceolate or occasionally oblong to elliptical, 0.6-2.5 mm long, ventral surface keeled to broadly keeled; apex acute to acuminate, occasionally apiculate, with a single clear tooth; base scarcely differentiated, decurrent; margins ± undulate above, rarely recurved below, entire or rarely with a single tooth above, entire to crenulate below, unistratose. Costa ending below apex; ventral and dorsal superficial cells long-rectangular to linear; in section subround to round, bulging dorsally, guide cells exposed ventrally, dorsal stereid band 1-3 cells thick, dorsal surface cells not differentiated, ± rough. Upper laminal cells irregularly rounded-hexagonal, flat, 7.5-15.0 µm, papillose to densely papillose, papillae 4-7, scattered over lumen, low and blunt; basal cells short-rectangular to quadrate, thin-walled to incrassate or transverse walls incrassate, smooth or with a single papilla over lumen or walls papillose. Gemmae produced on stem, filiform or clavate, uniseriate, with transverse septa, (2)3-5 cells long, reddish brown. Dioicous. Perigonia and perichaetia terminal, quickly overgrown by innovations; perigonial leaves shortly ovate-apiculate or ovate-acuminate; perichaetial leaves scarcely differentiated. Seta 5-10 mm long, brownish. Capsule oblong-cylindrical or narrowly pyriform, 1.5-2.2 mm long, brownish, 8-ribbed, neck differentiated; exothecial cells quadrate to short-rectangular, incrassate, smaller at mouth; annulus apparently absent. Peristome fragile, exostome teeth rudimentary; endostome segments distant, ± linear, irregular in outline, 85-105 µm long, yellowish, essentially smooth, basal membrane absent. Operculum 0.8 mm long, ± oblique. Calyptra 2.0-2.5 mm long, smooth. Spores 17-25 µm.
