During an investigation of fungal diversity from freshwater environments in different regions in Jiangxi Province, China, four interesting species were collected.Morphology coupled with combined gene analysis of an ITS, ultrastar dc hc550 LSU, SSU, and rpb2 DNA sequence data showed that they belong to the family Pleurotheciaceae.Four new species, Pleurotheciella ganzhouensis, Pla.irregularis, Pla.verrucosa, and Pleurothecium jiangxiense are herein described.

Pleurotheciella ganzhouensis is characterized by its capsule-shaped icon track bar f250 conidia and short conidiophores, while Pla.irregularis has amorphous conidiophores and 3-septate conidia.Pleurotheciella verrucosa has cylindrical or verrucolose conidiogenous cells, 1-septate, narrowly fusiform, meniscus or subclavate conidia.Pleurothecium jiangxiense characterized in having conidiogenous cells with dense cylindrical denticles and short conidiophores.Pleurothecium obovoideum was transferred to Neomonodictys based on phylogenetic evidence.

All species are compared with other similar species and comprehensive descriptions, micrographs, and phylogenetic data are provided.
