All Spatoglossum and Stoechospermum species in Persian Gulf and Oman  Sea, Iran, have been so far identified via classical taxonomy. In this study classification of two genus of brown algae (Dictyotaceae) including Spatoglossum and Stoechospermum have been investigated. We combined the cytoplasmic DNA sequences data of plastid rbcL and psbA with morphological information. Based on the constructed phylogenetic trees on the sequences data of these two genes the collected specimens from the Iranian coastlines made two distinct clades which were grouped with two species Stoechospermum polypodioides and Spatoglossum crassum with high to full bootstrap values. So we approved the presence of Stoechospermum polypodioides and  Spatoglossum crassum as new record for the algal flora of Persian Gulf in Iranian coastlines.
