Polypore refers to a type of fungus that typically grows on wood and has a distinctive, shelf-like appearance. These fungi belong to the class Agaricomycetes and are known for their porous surfaces, which contain numerous tiny holes or pores. Polypores play a crucial role in ecosystems by breaking down dead wood and recycling nutrients back into the soil. Many species of polypores are found worldwide, and they can vary in color, size, and shape. Some well-known examples include Turkey Tail and Artist's Conk. While some polypores are edible, others are not, and some can even be toxic, making identification important for foragers.
