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.]
