| Summary: | Symplectoscyphus sp. 1 (Figs 12 J, 13C) Material examined. Stn 7, stem 5 mm high on Schizotricha turqueti (MNCN 2.03/644); Stn 17, two stems up to 11 mm high on Schizotricha turqueti (NIWA 117589). Description. Monosiphonic, straight stems, up to 11 mm high. Stem divided into short internodes (shorter than hydrothecae). Distal part of hydrotheca reaching basal part of following alternate one. Hydrothecae (Figs 12 J, 13C) relatively large, almost cylindrical, abcaudally directed. Adcauline hydrothecal wall adnate to internode for more than half its length. Free part of adcauline hydrothecal wall roughly straight; adnate part usually convex. Abcauline hydrothecal wall slightly convex basally, concave by the middle. Cusps of hydrothecal aperture sharp, separated by deep embayments. Measurements (in µm). Hydrothecae: length abcauline wall 350–450, length free part of adcauline wall 230–300, length adnate part of adcauline wall 310–330, length adcauline wall 540–610, diameter at aperture 200–210, diameter at ... : Published as part of ÁLVARO L.
