2. End Show 21-2 Classification of Fungi Slide 2 of 44 Copyright Pearson Prentice Hall Classification Fungi are classified according to their structure and method of reproduction. The four main groups of fungi are: 1) Common molds (Zygomycota) 2) Sac fungi (Ascomycota) 3) Club fungi (Basidiomycota) 4) Imperfect fungi (Deuteromycota)

Example = Penicillium notatum - a mold that is the source of the antibiotic penicillin.
