Stem leaves loosely erect-appressed and often slightly contorted when dry, narrowly lanceolate to oblong-lanceolate, 2–3.6 mm; margins revolute to near apex, entire; apex acute; basal laminal cells elongate-rectangular, walls thick, nodose; distal cells 7–14 µm, 1-stratose, papillae 2 or 3 per cell, conic, size moderate. Specialized asexual reproduction absent. Sexual condition gonioautoicous. Seta 0.5–1.6 mm. Capsule 1/2–2/3 emergent, sometimes immersed or fully exserted, oblong to oblong-cylindric, 0.8–1.5 mm, strongly 8-ribbed 1/2–2/3 length; stomata superficial; peristome double; prostome rudimentary or absent; exostome teeth 8, reflexed, reticulately papillose to obscurely papillose, deeply perforate, cancellate; endostome segments 8, well developed, usually present when capsule is old and dry, narrow, of 1 or 2 rows of cells, smooth or finely verrucose. Calyptra oblong-conic, smooth, sparsely hairy, hairs smooth or papillose. Spores 19–29 µm.
