  • Description

    Species Description - Stems (3-)10-20(-55) mm high, in section round, elliptic, or rounded-triangular. Propagula sometimes borne on hyaline stalks in leaf axils, consisting of 5-9 cells in numerous rows, 35-50 µm long, not abundant. Leaves erect-incurved to straight and ± spreading, occasionally twisted, curled, or tubulose w h e n dry, occasionally very fragile, (0.3-)1-2(-2.5) mm long, broadly rounded and sometimes ± cucullate to narrowly acute at the apex, oval or scarcely differentiated at base, not sheathing or decurrent; costa ending 1-3 (-6) cells below the apex to percurrent or occasionally excurrent as a short, stout mucro, covered ventrally by subquadrate to rectangular, smooth or papillose cells, the ventral stereid band occasionally much reduced; upper cells (6-)8-10(-15) µm wide, usually about 1:1, occasionally transversely rectangular in patches at the margins or elsewhere; basal cells usually differentiated in a rectangular group or extending upward along the margins, smooth or weakly papillose, pellucid, mostly short-rectangular, not or distinctly broader than the upper cells, usually 9-12 µm wide, 2-3:1. Setae 3-7 mm long; capsules 0.6-1.5 mm long; operculum (0.4-)0.8-1.2 mm long, its cells not in spiral rows. Spores (7-)9-12(-15) µm, nearly smooth to lightly papillose.

    The leaves vary in length and shape, but heterogeneous leaf cells distinguish this species from others of some game tophytic similarity: Anoectangium aestivum (which also has lateral inflorescences) has deeply channeled leaves.

    Tuerckheimia angustifolia has 1-2 or 3 massive, granulose or compound papillae per cell.
