Pelatocladus maniniholoensis

Johansen and Vaccarino, 2016 ( Fig. 2 , Table 2)

Colony bright blue-green in color. Filaments of main axis straight, uniseriate, mostly one-sided laterally branched, distinctly constricted cross-walls, lacking sheaths. Cells of main axis filaments 5-8 μm wide, 6-11 μm long. Filaments of branches never branching when attached to main axis, rounded at base, becoming cylindrical and elongated. Cells of branch filaments 3.5-5.1 μm wide, 4-13 μm long. Heterocytes intercalary, lateral and terminal, 5.1-7.7 μm wide, 9-12 μm long in the main axis, typically more elongated in the branched regions. Sometimes hormogonia with distinct sheaths.

Ecology. On the walls of a cave ( Miscoe et al., 2016), attached to rocks in Korea.

Distribution. Hawaii ( Miscoe et al., 2016).
