Antarctoscyphus admirabilis Peña Cantero, Svoboda & Vervoort, 1999 (Fig. 12 A) Antarctoscyphus admirabilis Peña Cantero et al., 1999: 1742 –1745, figs 1, 7A. Material examined. Stn 17, stem fragment 65 mm long (MNCN 2.03/618); Stn 91, colony 180 mm high (NIWA 117546). Measurements (in µm). Hydrotheca: length of abcauline wall 620, length of free part of adcauline wall 680, length of adnate part of adcauline wall 70, length of adcauline wall 750, diameter at aperture 230, maximum diameter 230. Cauline internodes: 1700 x 750. Remarks. This uncommon species is easily distinguishable by its polysiphonic and branched stems, divided into short and thick internodes not arranged in zigzag, by its short, little branched, paired branches, with only a few hydrothecae and, sometimes, a few basal athecate internodes, and by the shape of the hydrotheca, cylindrical, but distinctly curved outwards, and with sharp cusps of similar development separated by deep embayments (Fig. 12 A).
