This research provides a major update to how we classify an important group of fungi, some of which form fascinating relationships with fungus-farming ants. The scientists discovered new groups of fungi and clarified how different species are related to each other. This helps us better understand fungal diversity and evolution. Impacts on everyday life: – Improves our understanding of beneficial relationships between fungi and insects – Helps identify and classify fungi that may have undiscovered uses – Contributes to knowledge of fungal biodiversity and conservation – Provides insights into evolution of fungal-insect partnerships – May lead to discoveries of new compounds or applications from these fungi
