title: Redefining common endophytes and plant pathogens in Neofabraea, Pezicula, and related genera.
abstract: Species in Neofabraea, Pezicula, and related genera have been reported as saprobes, plant pathogens or endophytes from a wide range of hosts. The asexual morphs of Neofabraea and Pezicula had been placed in Cryptosporiopsis, now a synonym of Pezicula, while Neofabraea was also linked to Phlyctema. Based on morphology and molecular data of the partial large subunit nrDNA (LSU), the internal transcribed spacer region with intervening 5.8S nrDNA (ITS), partial β-tubulin region (tub2), and the partial RNA polymerase II second largest subunit region (rpb2), the taxonomy and phylogenetic relationships of these fungi were investigated. Five new species were described in Pezicula based on morphology, while a further eight unnamed phylogenetic lineages revealed further diversity in the genus. Based on these results, the generic concept of Neofabraea was also emended. Phlyctema, which was previously associated with Neofabraea, formed a distinct clade, separate from Neofabraea s. str. Two new neofabraea-like genera, Parafabraea and Pseudofabraea were proposed, along with one new combination in Neofabraea s. str. To stabilise the application of these names, an epitype was designated for Pe. carpinea, the type species of Pezicula, and for N. malicorticis, the type species of Neofabraea.
