Additions and corrections to names published in Cercospora in Iran

In this paper the taxonomy of some previously reported taxa as Cercospora apii s.lat. in Iran, is discussed and some new records are listed. Cercospora species on Abelia grandiflora (C. deutziae), Erythrina cristagalli (C. erythrinicola), Euphorbia heterophylla (C. pulcherrimae) and Zanthedeschia aethiopica (C. richardiicola) are new for mycobiota of Iran. Cercospora iridis which was previously reported from Iran probably belongs to the genus Passalora, but more specimens should be examined for final conclusion.
