2.生态学在自然条件下,真菌并不是单独生活而是与其它生物相联系的。共生,意味着以一种平衡联系共同生活,对于在自然条件下生存的生物这是一种规律。有一些食用菌种类(如双孢蘑菇、香菇、金针菇、草菇和各种侧耳等)当与在自然条件下通常相联系的生物分离时仍能正常生长和形成子实体。但另一些食用菌可能与在自然条件下另一生物有十分密切的联系,这就使得在人工单独栽培这些食用菌
2. Ecology In natural conditions, fungi do not live alone but are linked to other organisms. Symbiosis means that living together in a balanced way is a rule for creatures that live under natural conditions. Some species of edible fungi (such as Agaricus bisporus, Mushroom, Flammulina velutipes, Straw mushroom, various ear, etc.) can still grow and form fruiting bodies normally when separated from organisms normally associated with natural conditions. However, other edible fungi may be very closely linked to another organism under natural conditions, which makes it possible to grow these edible mushrooms by themselves
