This research discovered that more species of mushroom-forming fungi in the Armillaria genus can produce their own light (bioluminescence) than previously known. The study found five new glowing species and confirmed four others, showing that this characteristic is more common in these fungi than scientists thought. Impact on everyday life: • Helps in identifying harmful tree-rotting fungi in forests and gardens • Advances our understanding of natural light production in organisms • Could lead to development of natural lighting technologies • Improves forest management and tree health monitoring • Contributes to potential biotechnology applications using bioluminescent organisms
