1, mushrooms have white hair after a few days, and you can eat them if they are not serious.

2. Mushroom consists of mycelium and fruiting body. Mycelium is a vegetative organ, and fruiting body is a reproductive organ. If mushrooms have long white hairs, the spores of mushrooms usually grow mycelium because of the aging of mushrooms, which is common in Pleurotus ostreatus and Pleurotus eryngii every day. This aging mushroom will not produce toxic substances.

It's just that the taste of the food is somewhat reduced, and it can still be eaten after washing without any serious problems. However, if the long white hair is serious, it is best to throw it away and not eat it, which may be close to rot and deterioration, and eating it is harmful to health.
