Leaves to ca. 3.5 mm, erect-patent, weakly secund, lanceolate to linear-lanceolate, gradually acuminate to a channelled subula, acute, lamina 1-stratose except on margins; margins bistratose, entire or serrulate near the apex, irregularly thickened and recurved at least in distal half; costa stout, percurrent to excurrent, in section with abaxial stereid band; proximal lamina cells elongate-rectangular, distal lamina cells subquadrate to short-rectangular or somewhat irregular in outline, ± incrassate. Specialized asexual reproduction by rounded to pyriform or irregularly-shaped, yellow to orange rhizoidal tubers, to 150 µm. Sexual condition dioicous; perichaetial leaves similar to stem leaves but with a somewhat longer subula narrowing more abruptly from the base. Seta becoming reddish with age, to 1.5 cm, erect. Capsule erect, dark brown to reddish brown, ovoid to cylindrical, symmetric, 1-2 mm, smooth to ± furrowed when dry; operculum obliquely conic-rostrate, blunt, 0.3-0.7 mm; peristome split nearly to the base into 2 segments, brown, densely and finely obliquely-ridged and lightly papillose, 200-250 µm.
