Phoma tracheiphila is a fungal plant pathogen. It causes a disease known as Mal secco on citrus trees. It occurs in dry, cool climates such as the Mediterranean, Black Sea and Asia Minor. It forms pycniospores that are carried short distances by rain, or by wind to new leaves, where germinated hyphae invade stomata or more likely fresh wounds.CITRUS F:S Davies et al.1999
