- Abstract
Diaporthe species in China are highly diverse but still mostly unexplored. In this study, Diaporthe specimens were collected from symptomatic leaves in Yunnan Province. Identification was done using combination of morphology and comparison of DNA sequence data of the nuclear ribosomal internal transcribed spacer (ITS), β-tubulin (TUB), partial translation elongation factor-1α (TEF), calmodulin (CAL) and histone H3 (HIS) gene regions. Two new species, viz. D. clausenae and D. theobromatis, were found on Clausena anisata and Theobroma cacao, respectively. They are illustrated and described morphologically and phylogenetic relationships with other Diaporthe species are discussed.
