New records of fungi from rhizosphere of oak trees for Iran fungal flora

The objective of the present study was to isolate and characterize of fungal species from Persian oak trees rhizosphere in Zagros forests, Ilam province (Iran). For this purpose, sampling was performed from different regions of the above-mentioned forests during 2014–15. The serial dilutions of soil suspensions were cultured on Water agar (WA 2%), Potato dextrose agar (PDA), and Malt extract agar (MEA) media. Fungi were purified by transferring single hyphal tips on PDA medium.  At the first, the fungal isolates were identified using their morphological features. To confirm the morphological identification and taxonomic position of the isolates, molecular studied and phylogenetic analyses were then carried out using amplification and sequencing of ITS region of ribosomal DNA. Finally, the species Mortierella alpina, Penicillago nodositata,and Trichocladium jilongensis were identified based on morphological characters and molecular studies. These species were described and reported as new records for the mycobiota of Iran.
