Taxonomic re-evaluation of Korean Fungi through Korean Fungal Tree of Life and Barcode projects.

Molecular phylogenetic approaches have become essential tools for fungal taxonomic studies. The ‘Assembling the Fungal Tree of Life’ project was an important step in understanding the evolution and diversity of Fungi. One of the major accomplishments was to increase the amount of available sequence data in global databases (e.g., GenBank), facilitating fungal studies worldwide. In Korea, 4,085 species of fungi have been recorded based on morphological identification, To reevaluate fungal diversity and explore the use of fungal products for commercial purposes, the National Institute of Biological Resources of Korea launched the Korean Fungal Tree of Life and Fungal Barcode Project. Through these projects, we used multigene phylogenetic analyses (ITS, LSU, and RPB2) to reevaluate the species diversity of three major groups in relation to global species: genus Russula, genus Lactarius (including the Lactifluus), and polyporoid fungi (Fomitopsidaceae, Meruliaceae, and Polyporaceae), There were major discrepancies between morphological and molecular identifications; although Korean specimens were morphologically similar to species found in other countries (mostly USA, Europe, and Japan), most were phylogenetically distinct and may represent new species. For example, in the genus Russula Pers., 443 specimens were identified as 67 species, of which 22 species previously reported, 13 species new to Korea, and 32 species potentially new species. The same pattern was found for Lactarius (11 previously reported, 8 new to Korea, 35 new species) and polyporoid fungi (100 previously reported, 17 new to Korea, 25 new species), and show that fungal diversity in Korea is highly underestimated and needs further studies. Our findings illustrate the necessity of molecular methods in taxonomic studies, and highlight the need for further study, especially in unexplored regions such as Asia.
