Fungi classification is the process of organizing fungi into groups based on shared characteristics. The main categories include Ascomycota, Basidiomycota, and Zygomycota, which are distinguished by their reproductive structures and methods. Fungi can be unicellular, like yeasts, or multicellular, like mushrooms. Within these categories, fungi are further divided into classes, orders, families, genera, and species. This hierarchical system helps scientists identify and study different types of fungi, including molds and lichens. Understanding fungi classification is essential for research in ecology, medicine, and agriculture.
