A new Arthrinium -like genus of Amphisphaeriales in China

Species of are usually known as endophytes, pathogens or saprobes occurring on various hosts and substrates and are characterised by globose to subglobose, sometimes irregular, dark brown and smooth-walled or finely verruculose conidia, always with a truncate basal scar. Currently, contains two phylogenetically distinct clades, namely, and However, and have still not been properly classified. With new isolates from diseased leaves of collected in China, we propose the new -like genus in Amphisphaeriales. Based on the morphology and phylogeny of multiple loci, the new genus is established with the type species, and three new combinations, (syn. ), (syn. ) and (syn. ) are added to this genus.
