Study Notes
Characteristics
- Basidiomycetes are a group of fungi that belong to the phylum Basidiomycota
- They are characterized by the production of basidia, which are specialized structures that produce spores
- Basidiomycetes are heterotrophic, meaning they obtain their nutrients by decomposing organic matter or by forming symbiotic relationships with other organisms
Types of Basidiomycetes
- Mushrooms (e.g. Agaricus, Boletus, Amanita): fleshy, umbrella-shaped fungi that produce spores on the underside of their caps
- Bracket fungi (e.g. Ganoderma, Fomes): woody, shelf-like fungi that grow on trees and produce spores on the underside of their caps
- Puffballs (e.g. Lycoperdon, Calvatia): rounded, ball-like fungi that produce spores when mature and release them in a cloud-like puff when disturbed
- Rusts (e.g. Puccinia, Uromyces): fungi that infect plants and produce spores on the surface of their hosts
- Smuts (e.g. Ustilago, Sorosporium): fungi that infect plants and produce spores on the surface of their hosts
Reproduction
- Basidiomycetes produce spores through a process called basidiospory
- Spores are produced on the basidia, which are typically located on the underside of the cap or on the surface of the fungus
- Spores are dispersed through the air or by insects, and can germinate to form new individuals
Importance
- Basidiomycetes play a crucial role in decomposing organic matter and recycling nutrients in ecosystems
- They form symbiotic relationships with plants, such as mycorrhizal fungi, which help to increase plant nutrient uptake
- Some Basidiomycetes are edible and are used as a food source, while others are used in medicine and biotechnology
Characteristics of Basidiomycetes
- Belong to the phylum Basidiomycota
- Produce basidia, specialized structures that produce spores
- Heterotrophic, obtaining nutrients by decomposing organic matter or forming symbiotic relationships with other organisms
Types of Basidiomycetes
Mushrooms
- Fleshy, umbrella-shaped fungi
- Produce spores on the underside of their caps
- Examples: Agaricus, Boletus, Amanita
Bracket Fungi
- Woody, shelf-like fungi
- Grow on trees and produce spores on the underside of their caps
- Examples: Ganoderma, Fomes
Puffballs
- Rounded, ball-like fungi
- Produce spores when mature and release them in a cloud-like puff when disturbed
- Examples: Lycoperdon, Calvatia

Importance of Basidiomycetes
- Decompose organic matter and recycle nutrients in ecosystems
- Form symbiotic relationships with plants, such as mycorrhizal fungi, to increase plant nutrient uptake
- Some species are edible and used as a food source, while others are used in medicine and biotechnology
Characteristics of Basidiomycota
- Basidiomycota fungi are also known as club fungi
- They are characterized by the presence of club-shaped structures called basidia that produce spores
- Typically found in soil, decaying organic matter, and as symbionts with plants
Life Cycle of Basidiomycota
- Begins with the fusion of two haploid cells, resulting in a dikaryotic mycelium
- Dikaryotic mycelium grows and produces fruiting bodies, such as mushrooms
- Karyogamy occurs within fruiting bodies, resulting in a diploid nucleus
- Meiosis produces haploid spores that are dispersed and germinate into new haploid mycelia
Reproductive Structures of Basidiomycota
- Basidia: club-shaped structures that produce spores
- Cystidia: small, hair-like structures that aid in spore dispersal
- Fruiting bodies: mushrooms, brackets, and other structures that produce spores
Ecological Roles of Basidiomycota
- Decomposers: break down organic matter and recycle nutrients
- Mycorrhizal fungi: form symbiotic relationships with plant roots, providing nutrients in exchange for carbohydrates
- Pathogens: some species cause disease in plants and animals
Examples of Basidiomycota
- Mushrooms (e.g., button mushrooms, shiitake)
- Bracket fungi (e.g., turkey tail)
- Rust fungi (e.g., wheat rust)
- Smuts (e.g., corn smut)
