With which organisms do fungi enter into a symbiotic relationship? give examples

Many organisms are forced to enter into symbiosis in order to survive. Fungi often enter into symbiotic relationships with various organisms. The most famous such example is lichens. They consist of fungus and algae, which are in a mutually beneficial partnership. Mushrooms can also enter into symbiosis with trees. For example, boletus mushroom and aspen. The fungus, braiding the roots of the tree with its threads, helps it absorb water and minerals, and the tree supplies it with the nutrients it synthesizes.
