Steps/methods
1 Look at the growth area. Edible non-toxic mushrooms mostly grow on clean grasslands or pine trees and oak trees, while poisonous mushrooms often grow in dark, humid and dirty places.
Second, look at the color. There are poisonous mushrooms with bright colors such as red, green, black and blue, especially purple ones, which are often very toxic and easy to change color after picking.
3 look at the shape. Non-toxic mushroom cover is flat, the umbrella surface is smooth, the mushroom surface has no wheels, the lower part is sterile, the center of the poisonous mushroom cover is raised, the shape is weird, the mushroom surface is thick and hard, the mushroom handle has mushroom wheels, and the mushroom handle is slender or thick and easy to break.
4 look at secretions. Tear off fresh wild mushrooms, the nontoxic secretion is clear as water (some are white), and the mushroom surface will not change color after tearing off; The toxic secretion is thick and reddish brown, and it is easy to change color in the air after tearing.
Five smells. Non-toxic mushrooms have a special taste, while toxic mushrooms have a strange taste, such as spicy, sour and fishy.
6 6 is testing. When picking wild mushrooms, you can wipe the mushroom cover with onions. If the onion turns blue-brown, it proves that it is poisonous, otherwise it is nontoxic.
The seventh is the cooking test. When cooking wild mushrooms, put some rushes, some garlic or rice together, and the mushrooms will be cooked. When rushes turn blue-green or purple-green, they are toxic, while those that turn yellow are nontoxic. Garlic or rice is toxic when it changes color, but it is non-toxic when it remains unchanged.
Eight is chemical identification. Take out the juice of the suspected mushrooms collected or bought back, soak it in paper, and immediately add a drop of dilute hydrochloric acid or white vinegar to it. If paper turns red or blue, it will be toxic.
