Agaricus by Subhamita Das
Habitat Habitat Agaricus is an edible fungus and is commonly known as mushroom. In old literature it is known by the generic name Psalliota. It is a saprophytic fungus found growing on soil humus, decaying litter on forest floors, in the fields and lawns, wood logs and manure piles. It grows best in moist and shady places and is commonly seen during rainy season. It is cosmopolitan in distribution.
Systematic Position Kingdom: Fungi Phylum: Basidiomycota Class: Agaricomycetes Order: Agaricales Family: Agaricaceae Genus: Agaricus
Sexual Reproduction Sexual reproduction in Agaricus occurs when two compatible haploid hyphae of opposite mating types fuse together. This fusion is known as plasmogamy, resulting in the formation of a dikaryotic mycelium (having two genetically distinct haploid nuclei in each cell). The dikaryotic mycelium continues to grow and develop, and under the right conditions, it forms the visible fruiting body known as the mushroom. Within the mushroom cap's gills, specialized cells called basidia undergo karyogamy, a process where the two haploid nuclei within each basidium fuse to form a diploid nucleus. This diploid nucleus then undergoes meiosis to produce haploid spores once again, completing the life cycle of Agaricus.
