Diplasiolejeunea plicatiloba

Minute whitish green or pale yellow-green strands on other bryophytes or bark, dioicous. Specialised asexual propagules absent. Leaves broadly ovate to orbicular, 175–240 µm long, 125–300 µm wide, distant, inserted on the central dorsal row of stem cells and free margin extending up to opposite edge of stem but stem remaining visible dorsally between leaves, plicate and creating a rim around the end of the lobule furthest from the stem and a cavity beneath the lobule, with rounded or cuspidate apex pointing perpendicular to the stem and terminated by a single row of 1–2 cells; lobe margin crenulate due to bulging cells, forming a continuous curve with curve of keel or sometimes curving outwards from curve of keel; lobule orbicular to truncate-oblong, 150–210 µm long, 112–210 µm wide, with an inflated ovoid to ellipsoid section along the keel that flattens out toward the free margin, with 2 teeth directed parallel to stem or divergent at an acute angle from the stem, each 1–2 cells long, the tooth closest to stem often with basal tier 2 cells wide. Leaf cells polygonal to oblong or elliptic, 15–24 µm long, 10–17 µm wide, firm-walled, with small trigones, smooth, with granular oil bodies. Underleaves divided 0.4–0.6 of its length into two lobes, 67–105 µm long, 60–130 µm wide; lobes linear to narrowly lanceolate, widely divergent and separated by an obtuse to right-angled sinus rounded at base, 1–2 cells wide at base, terminating in a single row of 1–4 cells. Perianth pyriform, 400–450 µm long, 225–300 µm wide, 5-keeled, with a short cylindric beak at apex formed by a single tier of elongated cells.
