Description
Summary:Fungal biota represents important constituents of phyllosphere microorganisms. It is taxonomically highly diverse and influences plant physiology, metabolism and health. Members of the order <i>Diaporthales</i> are distributed worldwide and include devastating plant pathogens as well as endophytes and saprophytes. However, many phyllosphere <i>Diaporthales</i> species remain uncharacterized, with studies examining their diversity needed. Here, we report on the identification of several diaporthalean taxa samples collected from diseased leaves of <i>Cinnamomum camphora</i> (<i>Lauraceae</i>), <i>Castanopsis fordii</i> (<i>Fagaceae</i>) and <i>Schima superba</i> (<i>Theaceae</i>) in Fujian province, China. Based on morphological features coupled to multigene phylogenetic analyses of the internal transcribed spacer (ITS) region, the large subunit of nuclear ribosomal RNA (LSU), the partial beta-tubulin (<i>tub2</i>), histone H3 (<i>his3</i>), DNA-directed RNA polymerase II subunit (<i>rpb2</i>), translation elongation factor 1-α (<i>tef1</i>) and calmodulin (<i>cal</i>) genes, three new species of <i>Diaporthales</i> are introduced, namely, <i>Diaporthe wuyishanensis</i>, <i>Gnomoniopsis wuyishanensis</i> and <i>Paratubakia schimae</i>. This study contributes to our understanding on the biodiversity of diaporthalean fungi that are inhabitants of the phyllosphere of trees native to Asia.
