Morpho-phylogenetic evidence reveals novel hyphomycetous fungi on medicinal plants in Southwestern China

Summary

Researchers discovered and described 12 new species of fungi found on medicinal plants in southwestern China. By examining the fungi’s appearance under microscopes and analyzing their DNA, scientists confirmed these were previously unknown species. Some of these fungi may produce beneficial compounds while others produce toxins, highlighting the importance of understanding which fungi live on medicinal plants to ensure their quality and safety for human use.

Background

Medicinal plants are vital resources for preventing and controlling diseases, with over 70% of the global population relying on them for healthcare. Fungal pathogens and endophytes significantly influence the quality and clinical efficacy of medicinal plants. This study investigates the diversity of hyphomycetous fungi from medicinal plants in Southwestern China, focusing on families Dictyosporiaceae, Melanommataceae, and Stachybotryaceae.

Objective

This study aims to characterize and identify hyphomycetous fungi collected from medicinal plants in Southwestern China using morphological analysis and multi-locus phylogenetic assessments. The research introduces novel species and new host records to expand understanding of fungal diversity associated with medicinal flora.

Results

The study identified 39 hyphomycetous collections representing 19 distinct species across three families. Twelve novel species were described including Camposporium alangii, Dendryphiella verrucosispora, Jalapriya cheirospora, five Memnoniella species, two Sirastachys species, and Striatibotrys biguttulatispora. Additionally, seven new host or geographical records were reported.

Conclusion

This comprehensive investigation establishes a foundation for understanding fungal diversity on medicinal plants and contributes valuable insights for quality assurance of Chinese herbal medicines. The findings highlight the importance of investigating taxonomy and phylogeny of microfungi associated with medicinal flora for both ecological and medicinal value.
