Plants dark green to olive green. Stems 1-3(-4) cm, not or weakly julaceous, innovations few; rhizoids few on proximal stem. Leaves distant, somewhat contorted when dry, erect when moist, broadly ovate to suborbicular, concave, 0.5-2(-3.5) mm; base somewhat decurrent, red-green; margins plane or recurved proximally, 1-stratose, limbidium absent; apex broadly acute to obtuse; costa not reaching apex to rarely percurrent; proximal laminal cells rectangular, (60-) 80-100 × 16-24 µm, 3-5:1, bulging, walls thin; distal cells irregular, 25-50 × 16-25 µm, 1-2(-3):1, walls thin. Specialized asexual reproduction by rhizoidal tubers, on rhizoids at base of stem and in most proximal leaves, (200-)300-500 µm. Sexual condition apparently dioicous. Sporophytes unknown.
