Stems 1.5–2.5 cm. Leaves firm when wet, long-ligulate to broadly lanceolate from an oblong base, 1.5–2 mm, base oblong but not strongly sheathing, margins recurved or revolute to apex or nearly so, apex broadly acute to rounded; costa excurrent as a stout mucro, abaxial costal surface with scattered solid papillae, hydroids present; distal laminal cells firm-walled, quadrate, 7–9 µm wide, 1:1, papillose. Specialized asexual reproduction by spheric or occasionally elliptic gemmae on stalks in leaf axils, 30–35 µm long. [Perichaetial leaves weakly differentiated, antheridiate plants long-stemmed. Seta 0.9–1.5 cm. Theca 1–2.5 mm. Spores 8–11 µm.]
