Background: In this study, we introduce a novel genus, Paraeutypella, of the family Diatrypaceae comprising three species viz. Paraeutypella guizhouensis sp. nov. and P. citricola (basionym: Eutypella citricola) and P. vitis (basionym: Sphaeria vitis). Diatrypella longiasca sp. nov. is also introduced, which forms a distinct clade in Diatrypella sensu stricto. The discovery of this new genus will contribute to expanding the knowledge and taxonomic framework of Diatrypaceae (Xylariales). New information: Generic delimitations in Diatrypaceae are unsettled because the phylogeny has yet to be resolved using extensive taxon sampling and sequencing of ex-type cultures. During an investigation of xylarialean fungi, we collected eutypella-like fungi which is distinct from Eutypella sensu stricto in our phylogenetic analyses (ITS and beta-tubulin), thus, introduced as Paraeutypella guizhouensis gen. et sp. nov.. Paraeutypella is characterised by having 4-25 perithecia in a stroma each with 3-6 sulcate, long ostiolar necks. Paraeutypella citricola comb. nov. (basionym: Eutypella citricola) is introduced on Acer sp. from China. Diatrypella longiasca sp. nov. is introduced as a new species in Diatrypella sensu stricto. which has 2-5 ascomata per stroma and long ascospores, unusual when compared to other Diatrypella species and distinct phylogenetically.
