Mycorrhizal fungi, which form symbiotic relationships with plant roots, are crucial for ecosystem health. Recent research employed machine-learning on 25,000 global soil samples to map arbuscular and ectomycorrhizal fungal richness. The study reveals that global hotspots of mycorrhizal diversity are inadequately protected, emphasizing the need for targeted conservation efforts.

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants, largely resistant to degradation. This study unveils that "white rot" fungi exhibit inherent defense mechanisms enabling partial defluorination of perfluoroalkyl carboxylic acids (PFCAs). While not effective on legacy PFAS, their potential for PFCA defluorination suggests they are promising candidates in bioremediation efforts.

The Hydnaceae is a family of fungi primarily within the order Cantharellales, known for their significant ecological roles and varied morphology. Recent research in Costa Rica's neotropical Quercus forests has unveiled five novel species: Ca. neotropicalis, Cr. griseohymeninus, Cr. minutibrunneus, Cr. lamelligracilis, and Hydnum pallideflavum. This study marks a major step in expanding our understanding of Hydnaceae diversity in underexplored regions.

This study delves into the Didymellaceae family, notably Phoma-like fungi, associated with Convolvulaceae plants. Using multilocus phylogenetics, 16 species were confirmed, with three newly described: Didymella pseudomacrophylla, Epicoccum convolvulicola, and Epicoccum pseudoplurivorum. Seven species are newly reported in Russia, and one in Kazakhstan, highlighting their ecological breadth and diversity.
