The genus is characterised by denticulate, sympodially-extending conidiogenous cells and isthmospore conidia made of two or several cellular structures, which are connected by very narrow isthmuses. In this study, specimens with two and more cellular isthmic-segments were collected, respectively. Phylogenetic analysis inferred from two loci showed that our isolates grouped together with
