Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast; refer yeast for more information) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores(usually four). These specialized spores are called basidiospores. However, some Basidiomycota reproduce asexually in addition or exclusively. Basidiomycota that reproduce asexually (discussed below) can be recognized as members of this division by gross similarity to others, by the formation of a distinctive anatomical feature (the clamp connection - see below), cell wall components, and definitively by phylogeneticmolecular analysis of DNA sequence data.
