Stn 7, stem 225 mm high, basibiont of Sympletoscyphus sp. 1, and fragmented stem (largest fragment 80 mm long) (NIWA 117332); Stn 8, 45 stems up to 280 mm high, with male gonothecae, basibiont of Symplectoscyphus curvatus (NIWA 117333); Stn 13, six stems up to 220 mm high on gravel and pebbles (MNCN 2.03/668); Stn 15, ten stems up to 260 mm high, with male and female gonothecae, on shell fragments, stones and pebbles (NIWA 117334); Stn 17, ca. 30 stems up to 230 mm high on pebbles and stones, basibiont of Abietinella operculata and Symplectoscyphus sp. 1 (MNCN 2.03/669); Stn 18, two stems 220 and 110 mm high, and distal stem fragment 45 mm long (NIWA 117335); Stn 25, stem 180 mm high, with gonothecae, basibiont of Rhizorhagium antarcticum (NIWA 117336); Stn 37, stem 250 mm high, with male gonothecae (MNCN 2.03/670); Stn 67, stem 170 mm high, basibiont of A. operculata (NIWA 117337); Stn 96, stem 100 mm high (MNCN 2.03/ 671); Stn 105, basally truncated stem 65 mm long (NIWA 117338); Stn 150, three stems, 210, 130, and 190 mm high (NIWA 117339); Stn 178, nine stems up to 270 mm high, with gonothecae (MNCN 2.03/672); Stn 194, fragmented stem 150 mm high (NIWA 117340). Remarks. Species characterized by having unbranched stems, although secondary stems are sometimes observed (Peña Cantero & Vervoort 2005; Peña Cantero 2013). I also observed this in the material studied, but it seems to be associated to regeneration following fracture of the original stem (Peña Cantero & Vervoort 2005). A particular case is observed in the 180 mm high stem from Stn 25, in which first branching was clearly caused ...
