- In Azerbaijan chestnut (Castanea sativa) forms small patches in the natural mountainous forests growing together with other deciduous tree species. The chestnut blight fungus (Cryphonectria parasitica) was reported since 2008, and the continuous expansion of disease has been observed in the country. The purpose of present study was to identify the fungi other than C. parasitica isolated from the bark samples collected from chestnut blight cankers in 2015. The fungi were identified based on morphology, and ITS sequencing was used for confirming species identity. The obtained sequences were compared to those in the NCBI database. Results put all samples into three groups. Six of the specimens belonged to the ascomycetes: Diaporthe amygdale (≡Phomopsis amygdali), Epicoccum nigrum, Sirococcus castanea, Trichoderma koningiopsis, and Xenoacremonium falcatus showed a high identity to reference sequences in NCBI. Few sequences were identified with a generic name, such as Jattaea sp., Hypocrea sp., Eutypella sp. Sequences of four basidiomycetes (Coprinellus domesticus, Hyphodermella rosae, and Irpex lacteus) were identical to those in NCBI and one of the sequences was close to Polyporales sp. Two sequences were identified as zygomycete Umbelopsis isabellina. Epicoccum nigrum and Irpex lacteus were recorded on chestnut in Azerbaijan before. The other fungi represent new records for the country.
