Radaisia gomontiana Sauvageau has been studied for their morphology from the material collected from natural habitat and from cultures. The continuous collections of the organism from nature did not show any sign of baeocyte formation. However, in the seventeenth collection, after 2?months growth in a water body, it did reveal the formation of baeocytes only for 2?days, whereas under culture conditions, stages of baeocyte and monocyte formation were recorded as distinct features. The organism is identified as Radaisia (Hyellaceae) when baeocytes are observed. Its vegetative stage which is recognized as Cyanodermatium (Hydrococcaceae).
