Morphological and phylogenetic analysis reveal three new species Phyllosticta (Phyllostictaceae, Botryosphaeriales) in China

<i>Phyllosticta</i> (Phyllostictaceae, Botryosphaeriales) species have been reported worldwide and collected from various plant hosts. We proposed three new species, viz., <i>Phyllostictaelliptica</i> <b>sp. nov.</b>, <i>P.rhododendri</i> <b>sp. nov.</b>, and <i>P.wuzhishanensis</i> <b>sp. nov.</b>, based on multi-locus phylogenetic analysis using a combined dataset of ITS rDNA, LSU, <i>tef1</i>, ACT, and GPDH, along with morphological characteristics. Moreover, <i>P.capitalensis</i>, isolated from the leaves of <i>Mangiferaindica</i>, is redescribed herein. We have re-examined the six species complexes: the <i>P.capitalensis</i> species complex (including 32 species), <i>P.concentrica</i> species complex (including 32 species), <i>P.cruenta</i> species complex (including 22 species), <i>P.owaniana</i> species complex (including six species), <i>P.rhodorae</i> species complex (including two species), and <i>P.vaccinii</i> species complex (including two species). Detailed descriptions and illustrations of the new species are provided. These findings enrich the biodiversity of fungi and provide reference for subsequent research.
