This research identified three new species of fungi that can contaminate and damage commercially grown edible mushrooms. Understanding these contaminating fungi is crucial for protecting mushroom crops and reducing economic losses in the mushroom cultivation industry. Impacts on everyday life: • Helps protect commercial mushroom production which affects food supply and prices • Improves quality control in mushroom farming • Contributes to better disease management in agriculture • Supports food security by reducing crop losses • Advances scientific knowledge of fungal biodiversity
