Campanularia undetermined
Campanularia sp. (Fig. 1F–G) Material examined. TAN 0602/420, several hydrothecae, on S. compressa (NIWA 144251). Description. Stolonal hydrorhiza giving rise to erect, slightly sinuous, smooth pedicels provided with a single distal hydrotheca. Hydrotheca elongated, bell-shaped (Fig. 1F), 800–1050 µ...

Stolonal hydrorhiza giving rise to erect, slightly sinuous, smooth pedicels provided with a single distal hydrotheca. Hydrotheca elongated, bell-shaped (Fig. 1F), 800–1050 µm high, resting on a basal spherule, 60 µm high and 70 µm wide, and provided with a distinct diaphragm (Fig. 1G), 110 µm in diameter, delimiting a basal chamber 70 µm high (Fig. 1G). Distinct inflexion point at diaphragm (Fig. 1G); hydrothecal diameter markedly increasing just above basal chamber, only slightly afterwards (maximum diameter at aperture, 340–520 µm). Hydrothecal aperture circular; rim provided with 16 blunt cusps (Fig. 1F), slightly directed inwards and separated by deep embayments. Larger microbasic mastigophores around 10 x 2.5 µm. Remarks.
