Plants small to medium-sized, in dense tufts, light green when young, golden or brownish yellow with age. Stems to 5(-10) cm, densely pinnate, branches 3-5 mm, curved and secund away from substrate. Stem leaves erect-appressed, ± homomallous, triangular-lanceolate, 1-2(-2.5) × (0.2-)0.4-0.7(-0.8) mm; base short-rounded, narrowly decurrent; margins plane or often recurved in places, minutely serrulate to subentire, ; apex long-acuminate, ; costa to 70-90% leaf length, often vanishing in plication, terminal spine sometimes present; alar cells subquadrate, 6-7 µm wide, region of 6-9 × 5-8 cells, distinctly delimited, not reaching margins; laminal cells linear-flexuose, 35-95 × 4-6µm; basal cell shape irregular, short, region in 2 rows, indistinctly delimited from more distal cells. Branch leaves appressed when dry, spreading when moist, narrowly lanceolate, (0.5-)0.7-1.7 × (0.1-)0.2-0.4 mm; margins plane or recurved at places, serrulate or serrate proximally, entire or minutely serrulate distally, ; apex acuminate; costa to 70-90% leaf length, disappearing in acumen, terminal spine sometimes present; alar cells subquadrate, 6-7 µm wide, region small, distinctly delimited; laminal cells linear-flexuose, 25-85 × 4-6 µm; basal cells in 1 (or 2) rows; distal cells smooth. Sexual condition phyllodioicous or dioicous. Seta 0.7-1.5 cm, rough. Capsule erect, cylindric, sometimes slightly curved, 2-2.5 mm; annulus separating by fragments; operculum long-conic; peristome hygrocastique; exostome teeth with long transitional zone; endostome basal membrane high, segments as long as teeth, very narrow, cilia very short or absent. Spores dimorphic; 10-14 µm or 16-20 µm.
