This research explored the relationship between orchids and their essential fungal partners in southeastern Australia. The study revealed that a single fungal species forms partnerships with multiple orchid species across a vast geographic range, while a second fungal species is found only in wet, boggy areas. This research helps us understand how these important plant-fungal partnerships work in nature. Impacts on everyday life: – Helps conservation efforts for endangered orchid species by identifying their fungal partners – Improves understanding of how to grow and propagate orchids for horticulture – Provides insights into how species adapt to different environmental conditions – Demonstrates the importance of preserving natural habitats that support these partnerships – Advances knowledge of how beneficial fungi disperse in nature
