Basidiomycota reproduce sexually by the creation of specialized club-shaped cells called Basidium end, which usually results in extra meiospores (usually four).
These specialized spores called basidiospores. However, some have Basidiomycota reproduce asexually, and may or may not also sexually reproduce. Asexual reproduction Basidiomycota (see below) can be members of this tribe to recognize obvious similarities with other reproduction processes. The creation of special anatomical feature (Terminal connection - see below), a part of the cell wall, and ultimately molecular phylogenetic analysis of DNA sequences.

Basidiomycota life cycle.
In contrast to higher animals and plants that are easily recognizable male and female colleagues, Basidiomycota life cycles(except Rust (Pucciniales)) tend to each other are different, it is compatible haploids mycelium, which consists generally of filamentous hyphae. Catch Typically haploid mycelia Basidiomycota plasmogamy compatible kernel and then migrate into each other's mycelia and a pair of vibrant core. Karyogamy delay, so that a compatible dikaryon nuclei remain in pairs, called. Hyphae are then told that dikaryotic.
Conversely, when haploid mycelia monokaryons enter life cycle. Often dikaryotic mycelium is more powerful than individual monokaryotic mycelia, and go over the substrate, in which to grow further in basidiomycota life cycle. Dikaryons may durable, lasting years, decades or centuries. Monokaryons neither men nor women. Either bipolar (unifactorial) or tetrapolar (bifactorial) mating system. This leads to the fact that after meiosis, which haploid basidiospores and the resulting monokaryons have cores that are compatible with 50% (if bipolar) or 25% (if pole) basidiospores her sisters (and the resulting monokaryons) because we must distinguish mating genes which are taking part in basidiomycota life cycle, so they are compatible. However, there are many variants of these genes in the population, and that more than 90% are monokaryons mutually compatible. It is as if there is still more sex.
