These fungi are characterized by their fruiting bodies, which can vary in size, shape, and color. Many species within this order are edible, while others can be toxic. The most well-known family within Boletales is the Boletaceae, which includes the popular porcini mushroom. Members of this order play essential roles in ecosystems, often forming symbiotic relationships with trees through mycorrhizal associations, helping with nutrient absorption and enhancing soil health.
