Paraeutypella guizhouensis gen. et sp. nov. and Diatrypella longiasca sp. nov. (Diatrypaceae) from China

In this study, we introduce a novel genus, , of the family Diatrypaceae comprising three species viz. sp. nov. and (basionym: ) and (basionym: ). sp. nov. is also introduced, which forms a distinct clade in sensu stricto. The discovery of this new genus will contribute to expanding the knowledge and taxonomic framework of Diatrypaceae (Xylariales). 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 sensu stricto in our phylogenetic analyses (ITS and β-tubulin), thus, introduced as gen. et sp. nov.. is characterised by having 4-25 perithecia in a stroma each with 3-6 sulcate, long ostiolar necks. comb. nov. (basionym: ) is introduced on sp. from China. sp. nov. is introduced as a new species in sensu stricto. which has 2-5 ascomata per stroma and long ascospores, unusual when compared to other species and distinct phylogenetically.
