New Species of Large-Spored in Section Associated with Compositae Plants in China.

is a ubiquitous fungal genus including saprobic, endophytic, and pathogenic species associated with a wide variety of substrates. It has been separated into 29 sections and seven monotypic lineages based on molecular and morphological data. sect. is the largest section, containing the majority of large-spored species, most of which are important plant pathogens. Since 2015, of the investigations for large-spored species in China, 13 species were found associated with Compositae plants based on morphological comparisons and phylogenetic analyses. There were eight known species and five new species ( sp. nov., sp. nov., sp. nov., sp. nov., and sp. nov.) distributed in the four sections of , , , and , and one monotypic lineage (). The multi-locus sequence analyses encompassing the internal transcribed spacer region of rDNA (ITS), glyceraldehydes-3-phosphate dehydrogenase (GAPDH), major allergen gene (Alt a 1), translation elongation factor 1-alpha (TEF1), and RNA polymerase second largest subunit (RPB2), revealed that the new species fell into sect. . Morphologically, the new species were illustrated and compared with other relevant large-spored species in the study. Furthermore, , , and were firstly detected in , , and in China, respectively.
