Life Cycle of Basidiomycetes
The Basidiomycetes share several characteristics with Ascomycetes regarding their general life cycle pattern. The haplophase somatic body, represented by primary mycelium, is produced by the basidiospore following germ tube germination. Often, oidia are produced by the main mycelium. The oidia can act as spores and produce primary mycelia, or they can participate in the development of dikaryotic secondary mycelia by spermatizing with other primary mycelia that are compatible with one another. Somatogamy between two suitable primary mycelia can also produce secondary mycelium. The basidium forms from the dikaryotic apical cell of the hypha of the secondary mycelium.
The dikaryotic hyphal cells may produce resting spores. A basidium is produced by each spore that is resting on germination. Karyogamy occurs in the diplophase condition that produces basidiospores, which is followed immediately by meiosis and results in the production of haploid basidiospores. The haplophasic somatic body is produced when the basidiospores germinate. The life cycle is completed. The three phases of the life cycle are the haplophase, dikaryophase, and diplophase, with the dikaryophase being significantly longer than the other two and nutritionally distinct from the haplophase. Additionally, the haplophase is visible. The diplophase, which is relatively brief in nearly all fungi, is followed by meiosis.

Biological classification can be defined as a method used to categorize and group living organisms based on their characteristics and functions. And this is also known as taxonomy. R.H. Whittaker divided living organisms into 5 kingdoms based on their cellular structure, complexity, reproduction, mode of nutrition, and phylogenetic relationships. The five kingdoms are Monera, Protista, Fungi, Animalia, and Plantae.
