In this study, four new Gnomoniopsis species were described based on multilocus phylogenies and morphological characteristics. Their similarity to other species was discussed, and an updated key to all recognized species in the genus was provided.
The fungal genus Gnomoniopsis (Gnomoniaceae, Diaporthales) has been reported all around the world and isolated from multiple plant hosts. Based on multilocus phylogenies from a combined dataset of internal transcribed spacer (ITS) region, the ribosomal RNA gene cluster, and partial regions of translation elongation factor 1 alpha (tef1) and partial beta-tubulin (tub2), in conjunction with morphological characteristics, we describe and illustrate herein four new species, including Gnomoniopsis diaoluoshanensis sp. Nov., G. lithocarpi sp. Nov., G. mengyinensis sp. Nov. and G. yunnanensis sp. Nov. Alongside this, their similarity and dissimilarity to morphologically-allied and phylogenetically-related species are annotated and discussed. For facilitating future identification, we update the key to all species currently recognized in this genus.
