Stem leaves erect to erect-spreading, lanceolate to narrowly ovate-lanceolate, acuminate, 1-2.5 mm; costa percurrent or short-excurrent, sometimes somewhat subulate; laminal margins recurved, smooth or finely serrulate distally; median and distal laminal cells irregular in shape, mixed quadrate, trapezoidal, short-rectangular, short- to long-rhomboidal, 14-75 × 8-13 µm, proximal cells quadrate to short-rectangular, similar to median and distal cells; leaves of innovations similar to stem leaves, not much reduced proximally. Perichaetial leaves broadly ovate-lanceolate, narrowly acuminate to subulate, sometimes flexuose to secund, same size as stem leaves; costae short to long excurrent, hairpoint pellucid, sometimes finely spinose; laminal margins recurved, smooth to finely serrulate; distal and median laminal cells similar to stem leaves, proximal laminal cells lax, wider, rectangular, 2-4:1, 35-115 × 12-25 µm, sometimes somewhat hyaline. Specialized asexual gemmae absent. Sexual condition autoicous; antheridia terminating axillary leaf buds. Capsule terminal, 425-750 µm. Spores typically 28(4-60) per capsule, angular to irregularly polyhedral, 120-230 µm, smooth or finely granulose, yellow to orange-red.
