Saccogynidium decurvum

Stems creeping, with clavate papillae. Rhizoids sparse, in fascicles from stem at base of underleaf. Leaves asymmetric, narrow-ovate with decurrent basiscopic margin, 675–2500 μm long, 750–2100 μm wide at base, concave ventrally, widely spreading, almost opposite and sometimes connate with the opposing leaf, usually bidentate at apex, sometimes with one tooth, or rarely truncate at apex without teeth. Underleaves orbicular in outline, bilobed, 450–1525 μm long, 475–1550 μm wide, free from lateral leaves, imbricate, appressed to stem, convex ventrally; lobes 1/10–1/3 length of underleaf, acuminate to acute, entire or with a single tooth. Leaf cells circular, polygonal or rectangular, 15–88 μm long, 15–48 μm wide, thin-walled, with distinct trigones, with numerous lageniform papillae, with 3–8 oil bodies in median cells; oil bodies spherical to ellipsoid, dull smoky grey, finely papillose. Marsupium long-cylindric, densely covered with hyaline rhizoids. Capsule 4–5-stratose. Elaters bispiral. Spores asperulate.
