Abstract: Seaweeds are the marine macro algae and represented globally with about 11,000 taxa, belonging to the division Chlorophyta, Phaeophyta and Rhodophyta. In India, seaweeds are represented with about 865 taxa. The two brown algal genera Chnoospora J. Agardh and Pseudochnoospora Santiañez, G.Y.Cho & Kogame belong to the family Scytosiphonaceae under the division Phaeophyta. The genus Chnoospora includes three taxa in the world and two taxa in India i.e.,Chnoospora bicanaliculata V. Krishnam. & P.C. Thomas and Chnoospora minima (K. Hering) Papenf. Whereas the newly established genus Pseudochnoospora is represented with only one species in the world as well as in India i.e. Pseudochnoospora implexa (J.Agardh) Santiañez, G.Y.Cho & Kogame. The species C. bicanaliculata is endemic to the Indian coast, whereas the species C. minima and P. implexa are economically very important and have therapeutic potentials. The present paper deals with the detailed taxonomic account of these three taxa in India including its economic potential.
