Species of Kionochaeta are saprobes commonly associated with decaying plant materials. As a part surveys on freshwater microfungi, Kionochaeta-like taxon was found submerged twig at rivulet in the protected forest area Khao Kheow Open Zoo (KKOZ), eastern Thailand. This is microscopically similar to Kionochaeta, but clearly differs by its accessory lateral setiform branches and sterile setae arising beside conidiophores. Multi-locus phylogenies inferred from four combined loci (SSU, ITS, LSU RPB2) demonstrated that this clustered as unique clade species (Chaetosphaeriaceae, Chaetosphaeriales). Therefore, we introduce K. setosimplicia, it phylogenetically close castaneae, ramifera pughii. setosimplicia separated microspora spissa. In 1, nanophora forms basal taxon. ivoriensis distinct 2 distant other Kionochaeta.
