* mushrooms, bracket fungi and puffballs are common basidiomycetes.
* they grow in soil, on logs, tree stumps and in living plant bodies as parasite.e.g.-rust and smut.
*the mycelium is branched and septate.
*vegetative reproduction by fragmentation is common in this class.
*asexual spore and sexual organ are absent.
*fusion of two different strain of somatic cell cause plasmogamy which give rise to basidium.
*basidium produces four basidiospore by karyogamy and meiosis.
* the basidia are arranged in fruiting bodies called basidiocarps.
*e.g.-Agaricus (mushroom), Ustilago (smut), Puccinia(rust fungus)
