Penicillium digitatum is a widespread pathogen among Rutaceae species that causes severe fruit decay symptoms on infected citrus fruit (known as citrus green mold). The spores of this mould are produced in dry chains and are exposed to the air hence their ease to become airborne. Penicillium digitatum disease symptoms on pome fruit. Consultez maintenant la liste complète des causes et des maladies possibles. The genus was first identified in scientific literature by Johann Heinrich Friedrich Link in his 1809 work Observationes in ordines plantarum naturale. J Microbiol Biotechnol.
