Thallus of Turbinaria a marine alga belonging to Phaeophyceae was studied and detailed micromorphological evaluation was done. Morphology of the thallus has been studied to aid pharmacognostic and taxonomic species identification using photographs; parameters presented in this paper may be proposed to establish the authenticity of this plant and can possibly help differentiate the alga from its other species. The study revealed several interesting characters like funnel shaped terminal bodies and its cellular details.
