Because black mushrooms are from the inside out, if even the appearance of mushrooms is black, it means that mushrooms have completely deteriorated at this time. Once taken, these mushrooms may cause diarrhea, vomiting and even serious food poisoning, so try not to eat black mushrooms.

Extended data:

Fresh mushrooms can be stored in cold storage, but before refrigeration, the scarred mushrooms should be removed, then sealed in a fresh-keeping box and put into the freezer, so that fresh mushrooms can be stored for about ten days without deterioration, and they are particularly fresh when taken out.

Fresh mushrooms have a short storage time, mainly because there is too much water in them. You can dehydrate them, but we want to remind you that fresh mushrooms should not be exposed to the sun directly, but should be dried in a cool and ventilated place, so as to avoid the loss of nutrients in mushrooms.
