Summary: | Symplectoscyphus densus sp. nov. (Figs 3 C, 12D–E, 14) Material examined. Stn 7, fragment 5 mm long (paratype, NIWA 115618); Stn 97, stem 7 mm high, slightly polysiphonic basally (holotype, NIWA 115617). Description (Holotype). Stem 7 mm high, slightly polysiphonic basally (Fig. 3 C). Stem with side branch (Fig. 3 C). Hydrothecae closely packed, alternately arranged, approximately planar (Fig. 12 D, 14A–B); almost opposite distally. Plane of hydrothecae of side branch roughly perpendicular to that of stem. Hydrotheca elongate (Fig. 12 D, 14A–D), diameter distinctly decreasing distally from median part (Fig. 12 D, 14A–D), sometimes looking like a distal neck (Fig. 12 D). Hydrotheca straight at basal half, curving abcaudally at distal half (Fig. 12 D, 14C–D). Hydrotheca free over half its adcauline length (Fig. 12 D, 14C–D). Free part of adcauline wall roughly straight or slightly convex; abcauline wall straight or slightly convex basally, concave distally. Rim of hydrothecal aperture with three ... : Published as part of ÁLVARO L.
