Scientists discovered two new fungal species belonging to the genus Periconia in China. These fungi were collected from freshwater streams and corn plants in Guangxi and Yunnan provinces. Using genetic analysis and microscopy, researchers confirmed these as previously unknown species and named them Periconia guangxiense and Periconia xishuangbannaensis. This discovery adds to our understanding of fungal diversity in China and shows that many fungal species remain yet to be discovered.
