Phylogenetic tree generated from a maximum likelihood analysis based on combined ITS, tef1, tub2, cal and his3 sequence data of the Diaporthe amygdali clade and closely related species. Bootstrap support values for maximum likelihood, maximum parsimony (ML-BS/MP-BS ≥ 70 %) and Bayesian posterior probabilities (PP ≥ 0.90) are shown at the nodes. Strains with type status are indicated in bold font. The isolates from this study are presented in brown typeface. Species boundaries within the D. amygdali clade are delimited with a coloured block and its respective branch is indicated by a lettered circle (A). The scale bar represents the expected number of nucleotide changes per site. The tree is rooted to D. acaciigena (CBS 129521).
