Septoria are ascomycete pycnidia-producing fungi that cause numerous leaf spot diseases on field crops, forages and many vegetables including tomatoes which are known to contract Septoria musiva from nearby cottonwood trees, and is responsible for yield losses. The genus is widespread, and estimated to contain 1072 species.[1] Pycnidia produce needle-like pycnidiospores.

Septoria apiicola is the cause of late blight of celery. It is characterized by the production of conidia within pycnidia. The symptoms include chlorotic spots that turn brown and necrotic. Septoria apiicola can survive on seeds.

Several species of passion flower are infected by several species of Septoria, and a fungus, which has been going by the name Septoria passiflorae but which is probably an undescribed species, has been used to control the invasive Passiflora tarminiana in Hawai'i.[2]
