Abstract :
The Didymellaceae is one of the most
species-rich families in the Pleosporales, and contains
numerous plant pathogenic, saprobic and endophytic
specie, inhabiting a wide range of ecosystems. To
identify the fungal species of the Didymellaceae in
Iran, we investigated nine unidentified phoma-like
strains obtained from the Iranian Fungal Culture
Collection (IRAN) and six additional strains obtained
from various diseased plants in Khuzestan Province,
during 2019–2021. The strains under study were
recognized by combining the results obtained from
multi-gene phylogenetic analyses (ITS, LSU, rpb2 and
tub2), and morphological comparisons. Accordingly,
six species belonging to four genera of the
Didymellaceae were identified and described as
follow: Didymella aquatica, D. segeticola, Ectophoma
multirostrata, Epicoccum dendrobii, E. tobaicum and
Neomicrosphaeropsis Juglandis. All these species are new records for the fungi of Iran. Furthermore, several
new hosts are reported for these taxa.
