Abstract

Members of the order Stigonematales are highly evolved and complicated group among blue-green alga. They show great diversity in their forms and structure. In present communication three strains of Westiellopsis (Westiellopsisprolifica, Westiellopsis iyengarii, Westiellopsis interrupta) have been studied. All (Westiellopsis prolifica, Westiellopsis iyengarii, & Westiellopsis interrupta), are multiseriate but Westiellopsis iyengarii showed conspicuous and early multiplication than others. These strains showed very characteristic and peculiar type of thallus structure on solid agar medium under culture conditions Westiellopsis prolifica forms cushion shaped structure, Westiellopsis iyengarii forms cushion like thallus with concentric ring at maturity whereas Westiellopsis interrupta forms star like radiating thallus. They also show great diversity in branching pattern, cells structure as well as in growth pattern. Akinetes are formed in all strains in very peculiar pattern in long chain.
