Can't the black fungus on the maple be eaten?
Whether the fungus is poisonous depends on the long trees and whether poisonous insects pass by. Generally, it grows better in ancient Sophora japonica and Sang Mu, followed by Zheshu. Auricularia auricula, born in other trees, makes people move after eating it, causing old diseases, anxiety under the ribs, damage to the back of meridians, and annoyance. As long as there are snakes and insects passing under the fungus, it is toxic, especially the fungus born on maple trees, which is very toxic. If you eat it wrong, you will laugh hysterically. If the collected fungus changes color, it is toxic, and the fungus that glows at night is also toxic. If you don't have insects, it will rot, and eating it will harm people.
