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

Abstract

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 phylogenies from a combined dataset of genes encoding internal transcribed spacer (ITS), large subunit of ribosomal RNA (LSU rDNA), translation elongation factor 1 alpha (TEF1α), actin (ACT) and glycerol-3-phosphate dehydrogenase (GPDH), in conjunction with morphological characteristics, we describe two new species P. oblongifoliaesp. nov. and P. pterospermisp. nov., as well as a new Chinese record P. capitalensis. Their similarity and dissimilarity to morphologically-allied and phylogenetically-related species are also annotated and discussed.
