Ancylothrix terrestris M.D.Martins and L.H.Z.Branco ,

2016 ( Fig. 3 )

Filaments fasciculated, bent at the ends, bright green in color. Sheath thin, firm, sometimes widen, colorless, rarely two trichomes in a single sheath. Trichomes straight, entangled, slightly or not constricted at cross-walls, attenuated at the end, without calyptra. Cells shorter than wide, often isodiametric, 2.1-6.2 μm long, 5.0-6.7 μm wide. Apical cells conical rounded or rounded.
