About the Orange Penicillium

Name: Penicillium vanoranjei

Kingdom: Fungi

Family: Trichocomaceae

How it made the Top 10: Distinguished by the bright orange color it displays when produced in colonies, this fungus was named as a tribute to the Dutch royal family, specifically His Royal Highness the Prince of Orange. It was reported in a journal published by the National Herbarium of the Netherlands. The newcomer was isolated from soil in Tunisia. This species also produces a sheet-like extra-cellular matrix that may function as protection from drought.

Etymology: Latin, vanoranjei: named in reference to the orange-colored (in Dutch, "orange" is "oranje") colonies produced by this species, after Willem-Alexander Claus George Ferdinand, "Zijne Koninklijke Hoogheid de Prins van Oranje" (translated from Dutch as "His Royal Highness the Prince of Orange") and the new king of the Netherlands upon the retirement of Queen Beatrix April 30, 2013.

Type material: Applied and Industrial Mycology Department, CBS-KNAW Fungal Biodiversity Centre, Utrecht, the Netherlands
