holobasidiomycetes

Holobasidiomycetes is a class of fungi within the phylum Basidiomycota. This class is characterized by the presence of a true basidium, which is a specialized reproductive structure that produces basidiospores. The basidium is typically club-shaped and is found in the hymenium, the spore-bearing layer of the fruiting body. The basidiospores are usually produced in chains or clusters and are typically small, round, and thin-walled. Holobasidiomycetes are known for their diverse range of fruiting body morphologies, which can include mushrooms, brackets, shelf fungi, and puffballs. This class includes many economically important species, such as those used in the production of mushrooms for food and those that cause diseases in plants and animals. Holobasidiomycetes are found worldwide and play important roles in ecosystems, contributing to nutrient cycling and decomposition.
