It is recommended not to eat moldy mushrooms. If you are reluctant to throw them away, you can wash them first, then cover them with a special paper towel in the kitchen, and then expose them to the sun, or dry them in a microwave oven. If it still has peculiar smell after such treatment, it should be discarded and inedible.
Secondly, moldy food will affect health and even cause cancer. A small bag of inorganic sodium chloride can be put into the plastic bag to prevent the sugar in the mushroom from seeping out and changing color, and prevent the wheat moth from laying eggs and hatching. In order to prevent pests such as mushrooms and moths, the storage room can also be fumigated with carbon disulfide for 24 hours before storage, and then stored after removing the residual gas.
