Summary
This research provides a comprehensive analysis of mushroom species in the genus Armillaria found in China. The study combines traditional mating tests with modern DNA analysis and physical examination to identify and describe eight new species. This work is important because:
• It helps scientists better understand and identify fungi that can cause tree diseases and wood decay
• It establishes standard methods for identifying these fungi worldwide
• It contributes to our knowledge of fungal biodiversity in China
• It helps in monitoring and managing forest health
• It demonstrates how different scientific approaches can work together to improve species classification
Background
The genus Armillaria includes important fungal plant pathogens and wood decay fungi. Over 281 names have been included in the genus but only 41-47 species are currently accepted. Modern systematics of Armillaria in China started 28 years ago, with 14 Chinese Biological Species recognized by 2004. However, most Chinese Biological Species have not been formally described as taxonomic species.
Objective
The main objectives were to: 1) Identify biological species of Armillaria through mating tests, 2) Design primers and perform Genealogical Concordance Phylogenetic Species Recognition (GCPSR), and 3) Formally describe new species from China.
Results
Sixteen Chinese Biological Species were identified through mating tests. Fifteen Chinese Phylogenetic Species were recognized based on GCPSR analysis. The biological and phylogenetic species boundaries were identical except for two taxa (CBS K and CBS G) which formed the same phylogenetic species. Eight new species of Armillaria from China were formally described based on the combined evidence.
Conclusion
The study successfully unified the concepts of biological species, phylogenetic species, and morphological species in Chinese Armillaria taxonomy. Both mating tests and GCPSR approaches proved equally important and complementary for species identification. The established GCPSR tool provides a standardized approach for identifying Armillaria worldwide.
