Phylogenetic and Morphological Evidence Reveal Five New Species of Boletes from Southern China

Summary

This research discovered and described five new species of mushrooms from forests in southern China. These fungi belong to a group called boletes that form important partnerships with trees, helping forests stay healthy. The study highlights how many undiscovered species may still exist in China’s forests. Impacts on everyday life: – Helps scientists better understand and protect forest ecosystems – Contributes to knowledge of fungi that could have future applications in food or medicine – Demonstrates the importance of preserving natural habitats that may contain undiscovered species – Improves our ability to identify different mushroom species in the wild – Advances our understanding of the relationships between fungi and trees in forest environments

Background

The order Boletales is one of the largest groups of Basidiomycota fungi, with most species being both ectomycorrhizal and edible fungi. They form mycorrhizal relationships with multiple plant families including Betulaceae, Dipterocarpaceae, Fagaceae, Pinaceae and Salicaceae, playing vital roles in forest ecosystems, water and soil protection, and vegetation restoration. While over 500 Boletales species have been reported from China, few have been documented from Jiangxi Province despite its high forest coverage and suitable climate for macrofungi.

Objective

To investigate and describe new species of boletes from the Wuyishan National Nature Reserve in Jiangxi Province, China through morphological and phylogenetic analyses.

Results

Five new species were identified and described: Austroboletus albus, Xanthoconium violaceipes, Xanthoconium violaceofuscum, Xerocomus rutilans and Xerocomus subsplendidus. Each species was characterized by distinct morphological features and formed well-supported independent clades in phylogenetic analyses.

Conclusion

The study revealed and formally described five previously unknown species of boletes from southern China, contributing to the documented fungal diversity of the region. The findings demonstrate that there are likely many undiscovered fungal species in Jiangxi Province’s forests.
