Lyngby, Denmark. Penicillium is a diverse genus occurring worldwide and its species play important roles as decomposers of organic materials and cause destructive rots in the food industry where they produce a wide range of mycotoxins. Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista , Eladia , Eupenicillium , Torulomyces and Thysanophora , which together comprise a large monophyletic clade. As a result of this, and the many new species described in recent years, it was necessary to update the list of accepted species in Penicillium.

Floccaria Grev. Some members of the genus produce penicillin , a molecule that is used as an antibiotic , which kills or stops the growth of certain kinds of bacteria. Other species are used in cheesemaking. According to the Dictionary of the Fungi 10th edition, , the widespread genus contains over species. The genus was first described in the scientific literature by Johann Heinrich Friedrich Link in his work Observationes in ordines plantarum naturales ; he wrote, "Penicillium.
