Basidiomycota is a major group of fungi known for producing spores on specialized structures called basidia. This group includes familiar organisms such as mushrooms, puffballs, and shelf fungi. Basidiomycota play essential roles in ecosystems as decomposers, breaking down organic matter and recycling nutrients. Members of Basidiomycota can be found in various habitats, from forests to grasslands. They can be classified into several categories, including mushrooms, toadstools, and rusts. Some species form symbiotic relationships with plants, aiding in nutrient absorption, while others can be pathogens affecting crops and trees.
