This research focuses on properly classifying two fungi that cause serious diseases in cultivated morel mushrooms. The scientists used genetic analysis and microscopic examination to determine that these fungi belonged to a completely new family of fungi that had been incorrectly classified before. This improved classification helps better understand these economically damaging mushroom pathogens. Impacts on everyday life: – Helps mushroom farmers better identify and manage crop diseases – Improves food security by supporting commercial mushroom cultivation – Advances scientific understanding of fungal evolution and classification – Contributes to protecting valuable morel mushroom crops – Supports the growing edible mushroom industry
