| Summary: | Staurotheca sp. (Fig. 11 F–I) Material examined. Stn 53, palmate colony 85 mm high, basibiont of Hebella plana, and colony fragment 22 mm long (NIWA 117545); Stn 67, one colony 45 mm high (MNCN 2.03/617). Description. Colonies palmate, up to 85 mm high and basally polysiphonic, with closely-knit mesh appearance due to frequent branching and anastomoses. Hydrothecae arranged in decussate verticils of three, resulting in six longitudinal rows of hydrothecae; few basal branches with decussate pairs. Hydrotheca (Fig. 11 F–I) immersed into branch in about half, or even less, of its volume. Adcauline hydrothecal wall with significant free portion (Fig. 11 G). Abcauline wall straight or slightly convex basally, but concave distally (Fig. 11 G, I). Hydrotheca cylindrical in lateral view (Fig. 11 I), directed outwards at distal part. Hydrothecal aperture circular, directed downwards. Hydrotheca with mushroom-shaped diaphragm. Measurements (in µm). Hydrothecae: abcauline wall 600–620, free part of adcauline wall ... : Published as part of ÁLVARO L.
