Mushrooms are fascinating. They arrived on Earth more than 400 million years ago. They exchange nutrients with trees, and they are a food source for slugs, insects, and other animals. We will also see how mushrooms feed, what their roles are in the environment, their lifestyles, and their relationships with trees.\n\nAttention: this is not a mushroom-picking activity. Under no circumstances will we gather any, and we will not specify whether they are edible or not.\n\nAudience: families from 10 years old\nFrom 2 p.m. to 4:30 p.m.
