This research discovered and described two new species of fungi living in mangrove forests in Thailand and Taiwan. The study shows how these microscopic organisms interact with mangrove trees, either living harmlessly within plant tissues or sometimes causing disease. This research matters for everyday life in several ways: • Helps protect mangrove forests by better understanding the organisms that affect tree health • Contributes to preserving coastal ecosystems that protect shorelines from erosion and storms • Advances our knowledge of biodiversity in important coastal environments • Provides baseline data for monitoring changes in mangrove ecosystems due to climate change • Could lead to discoveries of new compounds or applications from these fungi
