To tell you clearly, there is no clear way to judge whether mushrooms are poisonous or not. Mushrooms can be divided into toxic and non-toxic, but in the actual natural environment, it is difficult to ensure that non-toxic mushrooms will not grow in a toxic environment, so we can't just look at the varieties. In the season of picking mushrooms in our hometown, we usually pick mushrooms that we know and there are no poisonous plants around. But that's all. I often hear about mushroom poisoning every year.
