This research provides a clearer understanding of snow mold fungi that damage plants during winter under snow cover. The scientists reorganized the classification of an important snow mold fungus group by studying their characteristics, genetics, and how they reproduce. This improved classification helps better identify and understand these plant pathogens. Impacts on everyday life: • Better identification of harmful fungi helps farmers protect winter crops from damage • Improved understanding of cold-adapted fungi aids in developing winter-hardy plants • More accurate classification systems help predict and manage plant diseases in snowy regions • Knowledge of fungal diversity contributes to maintaining healthy agricultural ecosystems • Understanding cold-tolerant organisms has applications in food preservation and storage
