New species of Sphaerulina on Populus from Iran

In the framework of study on Septoria and Septoria-like species in Iran, a new species Sphaerulina osypianiae sp. nov. on Populus sp. is described using morphological and rDNA ITS sequencing data. DNA extraction, amplification and sequencing were performed using methods and protocols mentioned by Azimi (2011). The resulting 511-bp sequence obtained from isolate 52935 was deposited in GenBank. The sequence shared 99% identity with Mycosphaerella populi (=Sphaerulina frondicola) sequences available in GenBank (see table 1 for identities). NJ tree generated using TreeView Display Option in NCBI BLAST, supported Sphaerulina species on Populus from Iran as a distinct species from all other Sphaerulina species sequences on Populus.
