Plants medium-sized to large, forming mats, yellow-green above, brown below; corticolous. Primary stem up to 60 mm long, branching regularly, tomentose below; rhizoids smooth, reddish brown; secondary stem 4-14 mm tall, branching by subperichaetial innovations; in section inner cortex 10-12 cells across, incrassate, outer cortical cells smaller, in 1-3 rows, stereids, outer surface rough. Stem leaves ± distant, ovate-acuminate or ovate-subulate or shortly oblong-subulate, 1.0-1.7 mm long. Branch leaves crowded, erect-twisted to spirally twisted when dry, erect to erect-spreading when wet, ± rugose, unistratose; narrowly lanceolate, narrowly oblong-lanceolate or narrowly oblong-subulate, 1.5-2.3 mm long, keeled; apex acute to acuminate; margins plane, occasionally recurved on one side of leaf, entire to weakly prorate. Costa ending below apex to mucronate; dorsal and ventral superficial cells linear, smooth; in section subround to round, bulging dorsally, cells undifferentiated, stereids. Upper laminal cells irregularly rounded to oval, incrassate, flat to bulging, 7.5-18.0 µm, smooth; basal cells long-rectangular to linear, longitudinal walls strongly incrassate, smooth. Pseudautoicous? Perigonia not seen. Perichaetia terminal, frequently overgrown by subperichaetial innovations; leaves lanceolate, oblong-lanceolate, or oblong-acuminate, 2.2-2.8 mm long. Seta 8-13 mm long, reddish brown to brown. Capsule reddish brown to brown, mouth darker, weakly ribbed above; urn ovate-cylindrical, 1.0-1.2 mm long; neck up to 0.4 mm long, wrinkled when dry; exothecial cells irregularly quadrate to rectangular, smaller at mouth, incrassate. Peristome single; exostome teeth 16, loosely in 8 pairs, narrowly oblong, blunt, frequently irregular in outline, (85-)120-190 µm long, pale brown, finely papillose. Operculum 0.8 mm long. Calyptra mitrate, 2.2-2.5 mm long, laciniate below, essentially naked, yellowish brown. Spores 25-48 µm, minutely granulose; aniso-sporous.
