Basidiomycetes 担子菌纲 担子菌纲 Basidiomycetes n 1: large class of higher fungi coextensive with subdivision Basidiomycota [ synonym: { Basidiomycetes}, { class Basidiomycetes}] Fungi \ Fun" gi\ ( f[ u^] n" j[ imac]), n. pl.; sing. { fungus}. ( Biol.) A group of thallophytic plant- like organisms of low organization, destitute of chlorophyll, in which reproduction is mainly accomplished by means of asexual spores, which are produced in a great variety of ways, though sexual reproduction is known to occur in certain { Phycomycetes}, or so- called algal fungi. They include the molds, mildews, rusts, smuts, mushrooms, toadstools, puff balls, and the allies of each. In the two- kingdom classification system they were classed with the plants, but in the modern five- kingdom classification, they are not classed as plants, but are classed in their own separate kingdom fungi, which includes the phyla Zygomycota ( including simple fungi such as bread molds), Ascomycota ( including the yeasts), Basidiomycota ( including the mushrooms, smuts, and rusts), and Deuteromycota ( the { fungi imperfecti}). Some of the forms, such as the yeasts, appear as single- celled microorganisms, but all of the fungi are are eukaryotic, thus distinguishing them from the prokaryotic microorganisms of the kingdon Monera. [ Webster 1913 Suppl. PJC] Note: The Fungi appear to have originated by degeneration from various alg[ ae], losing their chlorophyll on assuming a parasitic or saprophytic life. In an earlier classification they were divided into the subclasses { Phycomycetes}, the lower or algal fungi; the { Mesomycetes}, or intermediate fungi; and the { Mycomycetes}, or the higher fungi; by others into the { Phycomycetes}; the { Ascomycetes}, or sac- spore fungi; and the { Basidiomycetes}, or basidial- spore fungi. [ Webster 1913 Suppl.]
