Piecing together the taxonomic puzzle of .

species are plant pathogenic fungi causing leaf spot diseases of various hosts, including arboreous and herbaceous plants. The morphological characteristics of their asexual morphs and leaf spot symptoms are like those of spp. Due to their similar morphology, species of have largely been subsumed under A recent revision of the genus based on morphological characteristics and phylogenetic relationships resulted in the separation of from . This study reveals the diversity of the genus in Japan, and the species relationships based on a multigene phylogenetic analysis. Moreover, results of our phylogenetic analysis revealed seven novel species ( and which are described, and two species ( and ) which are transferred to the genus . Ujat AH, Nakashima C (2024).
