Basidiomycetes (Club fungi)

Basidiomycetes grow on moist soil, logs, trunks of trees or as parasites.
Mycelium is septate and branched. Both the monokaryotic and dikaryotic mycelia are seen. Dikaryotic mycelium show dolipore septum and clamp connections.
Asexual reproduction is absent in basidiomycetes.
Sexual organs are absent in basidiomycetes.
Sexual reproduction is by somatogamy between cells of monokaryotic mycelium of opposite strains. It results in the formation of dikaryotic mycelium which gives rise to basidium.
In the basidium karyogamy takes place. The diploid nucleus undergoes meiosis and later basidiospores are formed exogenously on the basidium.
The fruiting body of basidiomycetes is called basidiocarp.
Basidiomycetes include mushrooms, toadstools, bracket fungi and puffballs. Eg. Agaricus, Ustilago, Puccinia.
Ustilago tritici causes loose smut of wheat and U. maydis causes smut of corn.
Puccinia graminis causes black rust of wheat and Puccinia glumarum causes yellow rust of wheat.
Agaricus is edible while Amanita is poisonous.
