   Kingdom Fungi of Classes

• Phycomycetes
•  Ascomycetes
• Basidiomycetes
• Deuteromycetes.          
  
                                          (1)phycomycetes
• Found in aquatic decaying wood in moist and damp palace.
• Obligate parasite
• Mycelium is aseptate
• Coenocytic.
• Asexual reproduction
• Example for mucor, rhizopus, (bread mould ) and albugo (fungi on mustard plant).                       (2).  Ascomycetes
• Also called sac fungi 
• mostly multicellular 
•  Rarely unicellular e.g., Yeast.
•  saprophytic ,decomposer, parasite and coprophilos (grow on dung).
• Mycelium is branch and septate
• Mycelium called Conidiophores.
• Spores called ascospores.
• Fruiting bodies called ascocarps.
• Example are Aspergillus,claviceps and Neurospora.
• Neurospora used in biochemical and genetic work.                                                                            (3).  Basidiomycetes
• Grow in soil, logs and tree stumps and living plant bodies.
• Parasite ( rust and Smuts).
• Mycelium is branch and septate.
• Vegetative reproduction is fragmentation
• Dikaryotic stage found
• 4  Basidiospores are produce
• Fruiting bodies Basidiocarps.
• Example are -Agaricus(Mushroom) ,Ustilago (smut), and Puccinia (rust fungus).      
  
               (4).   Deuteromycetes
• Known as imperfect fungi.
• Mycelium is branch and septate.
• Decomposer : help in mineral cycling.
• Reproduce by asexual spores known as conidia.
• Example are Alternaria, Colletotrichum and Trichoderma.
