Plants light to dark green, loosely cespitose, crowded or sometimes forming a dense turf. Cauline leaves long-rectangular or less commonly lanceolate, straight to weakly reflexed apically, 0.4-0.6(-0.8) mm, apex rounded to broadly acute, occasionally apiculate; distal marginal cells sometimes 2-stratose in patches, distal laminal cells 5-8(-10) µm in width, 1-2:1; distal adaxial costal cells elongate, occasionally short-rectangular or quadrate in robust plants. Specialized asexual reproduction absent. Perichaetia often multiple on an axis, terminating short or rather elongate lateral branches; perichaetial leaves usually stiff and often secund, narrowly lanceolate to triangular, commonly with all cells elongate, rectangular to rhomboidal, smooth or weakly papillose, occasionally quadrate distally but then perichaetial leaves lanceolate or very strongly sheathing in proximal half. Capsule elliptical, with a circumstomal collar and bulging exothecial cells, usually 30-40(-50) µm wide.
