There is an urgent need to systematically manage fungal resources due to the increase in unrecorded and new species. Therefore, this study proposes standardized Korean names for 396 mushroom species, including approximately 300 species that previously lacked domestic nomenclature. Generic names were established based on the 1978 naming principles and the type of species. Family‒genus names were also unified. The proposed names reflect the etymological meanings of the Latin scientific names and their unique morphological characteristics. Previously misapplied nomenclature has been rectified and seven families, 12 genera, and 396 species out of 70 families and 150 genera have been given new or revised Korean names. This study will facilitate academic communication and minimize confusion regarding the nomenclature of domestic fungal resources.
