Morpho-phylogenetic evidence reveals two new species and two new host records of <i>Diaporthe</i> (Diaporthales, Diaporthaceae) from <i>Phellodendron chinense</i> in Sichuan, China.

ABSTRACT: Diaporthe species are globally distributed with a wide variety of plant hosts inhabiting diverse ecological niches and functioning as endophytes, saprobes and pathogens. Numerous species in this genus are significant pathogens responsible for a wide range of diseases in both agricultural and forest plants. In this study, eight Diaporthe strains were isolated from branches of Phellodendron chinense collected in Sichuan Province, China. Using multi-locus phylogenetic analysis of five gene regions (ITS, tef1-α, tub2, cal and his3), along with morphological characterisation, two novel species - D. phellodendri and D. leshanensis - are introduced in the present study and two new host associations were recorded for D. eucommiigena
