Pleurotus ostreatus is not strictly sterilized in the culture medium, sterilization is not strict during inoculation, and environmental sanitation is poor during the fruiting period, all of which can produce green mold. Green mold will be scrapped when it invades the culture material and the hyphae and mushrooms.
