Three new species of Camporesiomyces (Tubeufiaceae, Tubeufiales, Dothideomycetes) associated with coffee in Yunnan, China

Summary

Scientists discovered three new fungal species living on dead coffee branches in Yunnan, China. These fungi, belonging to the genus Camporesiomyces, are saprophytes that help decompose organic matter in coffee ecosystems. The discovery was confirmed through genetic analysis and detailed microscopic examination of the fungi’s structures. These findings could help researchers develop new biocontrol strategies for protecting coffee crops.

Background

Coffee is one of the most widely consumed beverages globally and an important traded commodity. While pathogenic fungi on coffee have been extensively studied, saprophytic fungi associated with coffee have received relatively less attention. Microfungi play a crucial role in coffee ecosystems as nutrient cycling organisms.

Objective

To identify and characterize three novel saprobic fungal species isolated from dead coffee branches in Yunnan Province, China. The study aimed to enhance understanding of fungal diversity associated with coffee trees through morphological and phylogenetic analyses.

Results

Three novel asexual species of Camporesiomyces were identified: C. bhatii, C. coffeae, and C. puerensis. Phylogenetic analysis showed these species formed distinct lineages within Camporesiomyces with strong statistical support. Detailed morphological descriptions revealed significant differences in conidial dimensions, conidiophore characteristics, and pigmentation.

Conclusion

This is the first report of Camporesiomyces species associated with coffee, adding three new asexual species to the genus. The findings significantly enrich understanding of fungal diversity in coffee ecosystems and have implications for identifying saprophytic fungi with potential biocontrol applications in sustainable coffee farming.
