Fereydouniaceae was introduced by Nasr et al. (2014) to accommodate the genus Fereydounia and species F. khargensis. Fereydounia khargensis has been identified in plant remnants of Iran (Nasr et al. 2014). These asexual species live freely in the environment and are not connected to any host plant. Ballistoconidia of these species are blastospores with retraction septate hyphae and pseudohyphae. Vegetative reproduction occurs through polar budding of blastospores in short stalks. However, sexual morph structures and teliospore production have not yet been identified (Nasr et al. 2014). The nuclear SSU, LSU (D1/D2 domain), and ITS rDNA molecular markers were used to elucidate the phylogenetic position of this family (Nasr et al. 2014).
