Morphological and phylogenetic analyses reveal two new species of Rhodoveronaea (Rhamphoriaceae, Rhamphoriales) from China

During a recent survey of freshwater fungi, four isolates were obtained from decaying wood in Chishui City, Guizhou Province, southern China. Based on phylogenetic analyses of a combined dataset (LSU, ITS, SSU, tef 1 - α, and rpb 2) and detailed morphological comparisons, two novel species, Rhodoveronaea aquisubtropica and R. guizhouensis, are introduced. Comprehensive descriptions, illustrations, and results of the phylogenetic analyses supporting the taxonomic placement of these new taxa are provided.

Additionally, a checklist of currently accepted Rhodoveronaea species supported by molecular data is included. Notably, R. aquisubtropica and R. guizhouensis represent the first records of Rhodoveronaea in the Chishui River Basin, thereby enriching the known diversity of subtropical freshwater habitats.
