Additions to the family Junewangiaceae (Sordariomycetes): novel species and new records from freshwater habitats in Southwestern China

<i>Junewangiaceae</i> (<i>Sordariomycetes</i>) is a family with a relatively recent taxonomic history and a small number of described species. However, a major challenge within this family is the inability to distinguish between various genera based solely on the phylogenetic analysis. In this study, we introduced two new species, <i>Junewangia guangxiensis</i> and <i>J. synnematica</i>, which formed independent clades in phylogenetic analysis and displayed characteristics that were easily distinguishable from other species within this family. Additionally, three previously known species, <i>viz.</i>, <i>Dictyosporella aquatica</i>, <i>D. thailandensis</i>, and <i>J. thailandensis</i>, are reported from China for the first time. Furthermore, <i>D. bambusicola</i> is documented from a freshwater habitat. The results enhance our understanding of <i>Junewangiaceae</i> and provide some suggestions for addressing the taxonomic problems of this family in the future.
