Lecanicillium fungicola is the causative agent of dry bubble disease in commercially cultivated mushrooms, primarily affecting Agaricus bisporus, Agaricus bitorquis, and Pleurotus ostreatus. The symptomatology ranges from minor necrotic lesions on the pileus to severe structural deformities, such as stipe blow-out or the formation of undifferentiated tissue masses known as dry bubbles. Regarding its economic impact, this pathogen is highly devastating, resulting in estimated annual losses of 2-4% of total revenue for the mushroom industry. Disease management necessitates rigorous hygiene protocols and the strategic application of fungicides. However, chemical control remains challenging due to the fungicide sensitivity of the host mushrooms.
