How to tell whether red mushrooms are poisonous or not

A look at the growing zone

Edible non-toxic mushrooms mostly grow in clean grass or on pine and oak trees, while poisonous mushrooms often grow in dark, damp and dirty areas.

Second, look at the color

The surface of poisonous mushrooms is brightly colored, including red, green, ink black, purple, etc. The purple ones in particular are often highly poisonous and tend to change color after being picked.

Three, look at the shape

The cap of non-toxic mushrooms is relatively flat, the umbrella surface is smooth, there are no rings on the surface, and there is no sterile stipe at the bottom. The cap of poisonous mushrooms is convex in the center and has a strange shape. The surface is thick and hard, there are sterile rings on the stalk, and the stipe is slender or thick and easy to break.

4. Look at the secretions

Tear off the stalks of freshly picked wild mushrooms. The non-toxic secretions are clear like water (some are white), and the surface of the mushroom does not change color when torn apart. The toxic secretions are thick and reddish-brown, and easily change color in the air after torn apart.

Five smells

Non-toxic mushrooms have a special fragrance, while poisonous mushrooms have strange smells, such as spicy, sour, and fishy.

Sixth, testing

When picking wild mushrooms, you can rub the mushroom cap with green onion. If the green onion turns green-brown, it is poisonous. Otherwise, it is non-toxic.

Seven is cooking test

When cooking wild mushrooms, add a few rushes and some garlic or rice together. When the mushrooms are cooked, if the rush turns green or purple-green, it is poisonous, and if it turns yellow, it is non-toxic. If the garlic or rice changes color, they are poisonous, and if they do not change color and remain their original color, they are non-toxic.

Eighth, chemical identification

Take the suspicious mushrooms that you have collected or bought, extract their juice, soak it with paper, and immediately add a drop of dilute hydrochloric acid or white vinegar on it. If the paper turns red or blue, it is poisonous.
