It also occurs on inter-tidal rocks, snow and even in cold lakes underneath 5 m of ice pack as well as in thermal springs. During systematic investigations recorded altogether 25 species, 4 variety and 2 forms from Maldah District viz. Oscillatoria acuta Bürhl and Biswas, Oscillatoria agardhii Gomont, Oscillatoria amoena (Kütz.) Gomont, Oscillatoria amphibia C.Agardh ex Gomont, Oscillatoria amphigranulata Goor, Oscillatoria angusta Koppe, Oscillatoria chalybea G.Mertens ex Gomont, Oscillatoria formosa Bory ex Gomont, Oscillatoria formosa f. loktakensis Brühl and Biswas, Oscillatoria geitleriana Elenkin, Oscillatoria geminata Menegh. ex. Gomont, Oscillatoria limnetica Lemmerm., Oscillatoria limosa C.Agardh ex Gomont, Oscillatoria minnesotensis Tilden, Oscillatoria okenii C.Agardh ex Gomont, Oscillatoria ornata var. crassa C.B.Rao, Oscillatoria perornata f. attenuata Skuja, Oscillatoria princeps Vaucher ex Gomont, Oscillatoria prolifica Gomont, Oscillatoria proteus Skuja, Oscillatoria pseudogeminata var. unigranulata Biswas, Oscillatoria quadripunctulata Brühl and Biswas, Oscillatoria raoi DeToni, Oscillatoria redekei Goor, Oscillatoria rubescens DC. ex Gomont, Oscillatoria splendida Grev. ex Gomont, Oscillatoria subbrevis Schmidle, Oscillatoria tenuis C.Agardh ex Gomont, Oscillatoria tenuis var. natans Gomont, Oscillatoria tenuis var. tergestina Rabenh. ex Gomont and Oscillatoria willei N.L.Gardner. However, Oscillatoria subbrevis Schmidle, Oscillatoria tenuis C.Agardh ex Gomont are the most common species followed by Oscillatoria amphigranulata Goor, Oscillatoria acuta Bürhl and Biswas, Oscillatoria amphibia C.Agardh ex Gomont, Oscillatoria amphigranulata Goor in water bodies of Malda District.
