White- to yellow-green strands growing on twigs and on other bryophytes. Leaves ovate to narrow-ovate, sometime with falcate lobe, 150–315 μm long, 65–140 μm wide, directed toward stem apex, acuminate to acute at apex, terminated by a single row of 1–2 cells and curved toward substrate, remote, not overlapping stem dorsally or occasionally extending over one cell row of stem, stem clearly visible from above, attached to stem dorsally by lobe and lobule and 6 cells, attached to stem ventrally by 3–4 cells of lobule; lobe margins crenulate by bulging cells; lobule ovate, 115–175 μm long, 67–100 μm wide, inflated, with bulging keel that seamlessly continues line of adjacent lobe margin, with a single prominent tooth angled away from stem, comprising a single elongate and falcate cell, with hyaline papilla at tooth base; leaf cells rounded-quadrate to oblong, 10–30 μm long, 9–20 μm wide, firm-walled, with small trigones, sometimes also with intermediate thickenings in cells of lobe, more frequent in cells of lobule, with single low dome-like papilla, most noticeable on keel. Underleaves divided to c. 2/3 into two lobes, 35–60 μm long, 50–100 μm wide; lobes linear, widely divergent, separated by an obtuse-angled sinus, 1–2 cells wide at base, ending in a single row of 2–3 cells. Perianth pyriform, 5-keeled.
