This research provides new insights into the diversity and classification of waxcap mushrooms (genus Hygrophorus), particularly focusing on a group of dark-colored, slimy species. The study reveals several previously unknown species and updates how these fungi are classified based on their evolutionary relationships. This work impacts everyday life in several ways: • Helps mushroom enthusiasts and experts better identify different species of waxcap mushrooms in the field • Improves our understanding of fungal biodiversity in different forest ecosystems • Contributes to conservation efforts by documenting fungal diversity in understudied regions • Aids in tracking the distribution of these fungi which form important partnerships with trees • Provides a foundation for future studies on the ecological roles of these fungi in forest health
