A new morphospecies, Microchaete goeppertiana Kirchner (Nostocales, Microcheataceae) has been reported for algal flora of Iran. Collection was done at ۲۰۱۱ from oil polluted regions of Khuzestan province. Identification performed using light, epifluoresence and phase contrast microscopy, in addition of behavioral analysis both in liquid and solid cultures. Observation and description were done in a multidisciplinary way including morphological variations in relation to pH and salinity concentration fluctuations at limited irradiance (۲ μE m-۲ s-۱). Regarding to biological versatility of cyanophyta, it has been tried to emphasize on most prominent traits for identification and determination. A new description of the species has been presented regarding to morphological characterization.
