A survey of the algal flora of the Osmania University campus revealed that it was rich. The total number of algal genera recorded were 68, out of which 32 genera belonged to Cholorophyceae; 19 to Cyanophyceae; 13 to Bacillariophyceae; 3 to Euglenophyceae; 2 to Charophyceaea and 1to Dinophyceae. It was very interesting to note that on Cladophora; Oedogonium, Characium & Stichosiphon were epiphytic. However highest number of genera were represented by Chlorophyceae. Epiphytic algae were present on unbranched filamentous Oedogonium and on branched filamentous Cladophora and Pithophora. It was Gomphonema and Achnanthes are attached to the other algal members by mucilaginous pad at their base.
