The genus Septoria Sacc. in Turkey

Seventynine Septoria species from 72 host plants have been identified in Turkey so far. There can be distinguished different interrelations between Septoria species and their host plants. So there are indifferent relationships between Cercis siliquastrum and S. cercidis, Petroselinum sativum and S. petroselini, Apium graveolens and S. apiicola, Cannabis sativa and S. cannabis presented negative consortium relationship. On Lycopersicum esculentum in high degree develop S. lycopersici. Between components of association they made antagonistic relationship, when infected plants perish. Some species of Septoria take part on the same substratum with other fungi species. In mycological association of S. tritici and Puccinia recondita and P. striiformis, S. tritici suppresses development of these rust fungi. The species S. convolvuli can be the example for mycological association with successive development of parasitic and saprobic components. The geographical elements of Septoria are represented by Holarctic (34.1%), Paleoarctic (16.5%), European–caucasian (11.4%), Mediterranean (10.1%), Holarctic with irradiation to South Hemisphere (6.3%), European with irradiation to West Asia (5.1%), European–caucasian–middle asiatic (3.8%), Mediterranean–paleoarctic (5.1%), Cosmopolitan (5.1%) and Caucasian (2.5%). S. valerianae Sacc. & Fautr. on Valeriana alliarifolia Adams. is a new record for Turkey.
