This research studied genetic and physical variations in a luminescent mushroom species found in Vietnam. The study revealed that despite showing many different appearances, these mushrooms all belong to the same species, with their varied looks being influenced more by environmental conditions than genetic differences. The findings impact everyday life in several ways: • Helps understand how fungi adapt to different environments while remaining the same species • Demonstrates that appearance alone is not always reliable for identifying species • Contributes to knowledge about bioluminescent organisms in nature • Aids in conservation efforts by clarifying species boundaries • Improves understanding of fungal diversity in tropical ecosystems
