The morphological and taxonomic studies on the genus Polysiphonia collected from Kalegauk Island were conducted from August 2016 to January 2017. A total of five species of the genus Polysiphonia were identified with their distinguishing characters. Among them, P. atlantica and P. howei were new records for

They are attached by rhizoids or haptera to a rocky surface or other alga. The thallus (tissue) consists of fine branched filaments each with a central axial filament supporting pericentral cells. Polysiphonia is a heterotrichous alga having an erect series of branches and a filamentous prostrate section attached to the substratum by means of unicellular rhizoids. The ends of the rhizoids are flattened into lobed discs called haptera, which assist the penetration of the host tissue ( Polysiphonia parasitic form) or confirm attachment to substrata. Polysiphonia, a common genus of marine red algae, is red in color because of the pigment phycobilin, which masks the green color of the chlorophyll responsible for photosynthesis. As a red-colored plant, Polysiphonia is well suited to absorb the green and blue-green light that typically penetrates the deeper seawater where these red algae thrive.

The Rhodomelaceae differ from other Ceramiales families by the formation of pericentral cells in an alternating fashion. Characteristics of the Rhodomelaceae based upon Scagel (1953), Hommersand (1963), Maggs & Hommersand (1993), Stegenga et al. (1997), Abbott (1999), and Womersley (2003) are listed below.
