Penicillium ulaiense is a plant pathogen that causes whisker mould.[1] It is considered an important infection of citrus fruit, especially in packinghouses. P. ulaiense is a citrus postharvest pathogenic fungus described as a member of the serie Italica,[2] together with P. italicum. In 1987, mycologists in Taiwan published a description of P. ulaiense.[1] Authors familiar with green and blue moulds of citrus had mistaken the fungus for P. italicum and dismissed its unique features as variations due to particular environmental conditions.[3] To date, P. ulaiense has been reported in Argentina, Arizona, Australia, California, Florida, Italy, New Zealand, South Africa, Taiwan, and Texas. In recent times, P. ulaiense has been reported in Egypt as a postharvest pathogen of orange fruit.[4]
