Value of species
Plants medium-sized, rarely large or small, in loose tufts, light green, often stramineous. Stems to 5 cm, ascending, arching, often curved distally, terete-foliate, irregularly pinnate, branches to 7 mm, often curved, terete-foliate. Stem leaves erect, imbricate or sometimes erectopatent, ovate, concave, not or slightly plicate, (1.2-)1.6-2.2 × (0.5-)0.7-1.1 mm; base broadly long-decurrent, ; margins plane or often recurved below broadest part of leaf, serrulate; apex short- to long-acuminate; costa to 55-75% leaf length, moderately weak, terminal abaxial spine absent; alar cells broader than juxtacostal cells, 15-25 × 12-16 µm, walls moderately thick, transverse perpendicular to their length, region conspicuous, appearing opaque because of collapsed cytoplasm; laminal cells elongate to linear, (25-)40-70(-110) × 6-10 µm; basal juxtacostal cells short-rectangular to ovate, shorter than laminal cells, region in 3 rows. Branch leaves with base asymmetric; margins recurved below broadest part of leaf on both sides, slightly serrulate; apex gradually acuminate; costa strong. Sexual condition autoicous. Seta reddish orange, 1.5-2 cm, rough, often indistinctly so. Capsule strongly inclined, horizontal, or pendent, reddish orange, usually short-ovoid, rarely ovoid-elongate, usually not curved or, when longer, slightly curved dorsally, 1.2-1.4(-1.7) mm. Spores 13-16 µm.
