Endophytic fungus, Radulidium subulatum from Phragmites australis in Iran

In order to isolate and identify endophytic fungi of Phragmites australis, numerous samplings were conducted from the plants grown in the southern areas of the Caspian Sea in Guilan, Mazandaran and Golestan provinces and saline soils around the Lake Urmia at province of East Azarbaijan. Twenty-one isolates of the genus Radulidium were obtained from healthy tissues of P. australis plants. Morphological studies and molecular analysis based on ITS-rDNA sequence revealed that the isolates belong to the R. subulatum. To the best of our knowledge, this is the first report of R. subulatum from P. australis to the mycobiota of Iran.
