Bracket fungi, also known as shelf fungi, are a type of fungus that grow on the sides of trees, logs, and other surfaces. They have a distinctive shelf-like shape, often resembling a bracket or shelf, and can vary in color and size. These fungi play a crucial role in the ecosystem by breaking down dead wood and recycling nutrients back into the soil. Bracket fungi belong to the group of fungi called basidiomycetes. They reproduce through spores, which are released from the underside of the brackets. Some species are edible, while others can be toxic. Their unique appearance and ecological importance make them a fascinating subject of study in mycology.
