Description Thallus blue-green, growth pattern appears like fascicles or bundles rather than forming a mat-like biofilm. Filaments isopolar, uniseriate, unbranched, cells slightly longer than their width, cell length ranged from 1.4 - 2.1 µm and width 0.9 - 1.1 µm. Cross walls have distinct constrictions. Trichomes were cylindrical, immotile, no heterocyte or akinete. Small sized filaments known as hormogonia helps in propagation. Necridic cells present. Ultrastructure includes parietal thylakoids, aerotopes present.

Type locality: Lothian island (21.39.1N 88.19.37E) of the Indian Sundarbans, India.
