摘要

In this study, we report the discovery of Jahnula dianchia sp. nov., a freshwater lignicolous fungus belonging to the order Jahnulales (Dothideomycetes, Ascomycota), from a submerged woody substrate from Dianchi Lake, Yunnan, China. Morphologically, this new taxon differs from other species of the genus in ascospore morphology; the ascospores of the new species are dark brown with mammiform apices. We also provide a phylogenetic tree showing the molecular relationships between the new taxon with the previously accepted Jahnula species. The analysis of combined ITS, LSU, and SSU sequence dataset places J . dianchia within the Jahnulales sister to J . sangamonensis . The phylogeny also shows the placement of both strains of J . dianchia in a well-supported independent sub-clade.
