Plants green to yellowish green, becoming brown with age, dull, in loose to somewhat dense tufts. Stems 2-5 mm, simple or seldom branched, with a few dark red rhizoids near the base. Leaves erect-spreading, slightly crisped to falcate-secund when dry, 1-3 mm, lanceolate to linear-lanceolate, channelled, lamina 1-stratose except near margins; margins plane to narrowly recurved from just beyond the leaf base to mid leaf, serrate to strongly serrate from mid leaf to the acute apex, 2-stratose distally and rarely a cell inward; costa distinct, percurrent, occupying 1/6-1/3 width of the leaf base; lamina cells thick-walled, distal cells 8-24 × 8 µm, becoming slightly broader and longer in the base. Specialized asexual reproduction unknown. Sexual condition dioicous. Seta orange-yellow, brownish or reddish, 0.8-1.2 cm, erect. Capsule erect, yellow or light brown, curved and asymmetric, 1-2(-2.5) mm, often swollen at the base; operculum rostrate, 0.5-0.8 mm; peristome 200 µm, 2-fid, the filaments ± unequal, linear, somewhat twisted when dry, strongly papillose to spiculose. Spores round, 9-13 µm, appearing smooth to minutely papillose.
