Morphological and phylogenetic analyses reveal two new species and a new record of Phyllosticta (Botryosphaeriales, Phyllostictaceae) from Hainan, China

The fungal genus Phyllosticta has been reported from all around the world and accommodates numerous pathogenic and endophytic species isolated from a wide range of plant hosts. Based on multilocus phy-logenies from a combined dataset of genes encoding internal transcribed spacer (ITS), large subunit of ribosomal RNA (LSU rDNA), translation elongation factor 1 alpha (TEF1 alpha), actin (ACT) and glycerol -3-phosphate dehydrogenase (GPDH), in conjunction with morphological characteristics, we describe two new species P. oblongifoliae sp. nov. and P. pterospermi sp. nov., as well as a new Chinese record P. capitalensis. Their similarity and dissimilarity to morphologically-allied and phylogenetically-related spe-cies are also annotated and discussed.

Automated summary

This study describes two new species and a new Chinese record of the fungal genus Phyllosticta, based on morphological characteristics and gene sequence analysis. The similarities and differences with morphologically-allied and phylogenetically-related species are also discussed.
