Polyphasic identification of Sepedonium microspermum isolated from two genera of Boletales in Iran

Moldy Boletus sp. and Xerocomus sp. were collected from several locations at the campus of the University of Tabriz, Iran. Fungicolous fungal isolates were recovered and characterized by the combination of morphological traits and phylogenetic analyses of combined ITS and LSU sequence data. Fungal isolates were identified as Sepedonium microspermum. This is the first report of S. microspermum on Xerocomus sp. from Iran which is comprehensively described and illustrated.
