Species of Diaporthe have been reported as plant endophytes, pathogens and saprobes on a wide range of plant hosts. Strains of Diaporthe were isolated from leaf spots of Smilax glabra and dead culms of Xanthium strumarium in China, and identified based on morphology and molecular phylogenetic analyses of combined internal transcribed spacer region (ITS), calmodulin (cal), histone H3 (his3), translation elongation factor 1-alpha (tef1) and β-tubulin (tub2) loci. As a result, two new species named Diaporthe rizhaoensis and D. smilacicola are identified, described and illustrated in the present study.
