Bracket fungi, also known as shelf fungi, are a type of fungus that grow on the sides of trees, logs, and other surfaces. They are characterized by their flat, shelf-like structures that extend outward, resembling brackets. These fungi play a crucial role in ecosystems by breaking down dead wood and recycling nutrients back into the soil. Bracket fungi belong to the group of fungi called Basidiomycetes. They can vary in color, shape, and size, with some species being brightly colored. Many bracket fungi are important for forest health, as they help decompose organic matter and support the growth of new plants.
