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 .

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 .
