Members of Diaporthales occur on a broad range of hosts and substrates, such as trees, crops, soil, and even living tissues of animals and humans, and comprise pathogenic, saprobic and endophytic species. This study was carried out to contribute to the knowledge of Diaporthales biodiversity in Iran. Juglanconis appendiculata from dead branch of Juglans regia in East Azerbaijan Province and Melanconiella chrysomelanconium from dead branch of Carpinus betulus in Golestan Province were identified using morphological characteristics and molecular data. Phylogenetic analysis of the elongation factor 1-alpha (tef1-α) gene using maximum likelihood approach strongly supported the placement of two Iranian isolates, i.e., IRAN 2457C (identified as J. appendiculata) and IRAN 5294C (identified as M. chrysomelanconium), within the Diaporthales. Both species are described and illustrated herein based on Iranian material and compared with closely related species. This study represents the first report of J. appendiculata and M. chrysomelanconium from Iran, providing geographic range extensions of both species.
