Explanation

Commonly known forms of class-Basidiomycetes are mushroom, bracket fungi or puffballs. The mycelium is branched and septate. The asexual spores are generally not found, but vegetative reproduction by fragmentation is common. Sex organs are absent, but plasmogamy is brought about by the fusion of two vegetative or somatic cell of different strains or genotypes. The resultant structure is dikaryotic, which ultimately gives rise to basidium. Karyogamy and meiosis take pleace in the basidium producing four basidiospores. The basidiospores are exogenously produced on the basidium. The basidia are arranged in fruiting bodies called basidiocarps
