Abstract
The status of species in the genus Diplodia was re-evaluated in terms of morphology and phylogeny based on ITS and TEF1 sequence data. Three distinct conidial morphologies were found. In one type the conidia become brown before they are discharged from the pycnidia and remain aseptate. In the second morphological type conidia are initially hyaline and aseptate and only after they are released from the pycnidia do they develop a septum and become coloured dark brown. Conidia of the third group are initially hyaline and aseptate, but only rarely do they develop a septum and become pale brown. The phylogenetic analyses resolved three main clades each one coinciding with three distinct morphologies of the asexual morphs. Two of the clades were well-supported by high bootstrap values in ML and MP while the third was weakly supported. This third clade consisted of a well-supported sub-clade comprising typical Diplodia species as typified by D. mutila and another comprising D. bulgarica, D. cupressi and D. tsugae, which are somewhat atypical of this genus. It was concluded that what was previously regarded as Diplodia comprises three distinct morphological and phylogenetic genera and two new genera are introduced here, namely Haplodia and Pidlodia. The status of D. bulgarica, D. cupressi and D. tsugae remains uncertain, but for the time being they are retained within Diplodia until more species can be studied and their phylogenetic position established.
