Two New Species of Jalapriya and a New Record, Dictyocheirospora vinaya from Freshwater Habitats in China

Summary

This research discovered two new species of fungi and documented another species for the first time in China, all found in freshwater environments. The study helps us better understand the diversity of microscopic fungi that play important roles in decomposing plant material in streams and rivers. Impacts on everyday life: – Helps track biodiversity changes in freshwater ecosystems – Contributes to understanding natural decomposition processes in streams – Advances knowledge of fungal species that could have future applications in biotechnology – Supports water quality monitoring through better understanding of aquatic organisms – Aids conservation efforts by documenting species diversity

Background

Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families within this order proposed to accommodate holomorphic saprobic Dothideomycetes. Currently 18 genera are recognised in Dictyosporiaceae.

Objective

To describe two new species of Jalapriya (J. aquaticum and J. apicalivaginatum) and report a new geographic record of Dictyocheirospora vinaya from freshwater habitats in China, based on morphological and molecular analyses.

Results

Two new species, Jalapriya aquaticum sp. nov. and J. apicalivaginatum sp. nov., were discovered and described based on distinct morphological characteristics and phylogenetic evidence. J. aquaticum differs in having rows converging at the apex and apical cells with spherical-like appendages. J. apicalivaginatum is characterized by having rows of conidia mostly arranged in a plane. Additionally, Dictyocheirospora vinaya was recorded for the first time in China.

Conclusion

The study expands the known diversity of Jalapriya with two new species and provides the first record of Dictyocheirospora vinaya in China. The findings contribute to our understanding of fungal diversity in freshwater habitats and the taxonomy of Dictyosporiaceae.
