Cephalotrichum asperulum and C. gorgonifer, two synnematous species from pistachio in Iran

In March 2019, a number of synnematous fungal specimens were isolated from the dead tissues of Pistachio vera (pistachio) seedlings in a greenhouse at the Azarbaijan Shahid Madani University of Tabriz, Iran. Preliminary identification based on morphological characteristics showed that the fungal isolates belong to the genus Cephalotrichum. Two species namely C. asperulum and C. gorgonifer were identified by combining morphology and phylogeny inferred from ITS-rDNA sequence. To our knowledge, C. gorgonifer is a new record for the Iranian Funga. Moreoverpistachio is matrix nova for C. aspeerulum and C. gorgonifer.
