Importance and distribution

Septocylindrium species are associated with leaf spot. There are 35 Septocylindrium epithets in Index Fungorum (2022), but several species have been transferred to other genera such as Cercosporella, Cladophialophora, Ilyonectria, Lylea, Monodidymaria, Passalora, Pseudocercospora, Pseudocercosporella, Ramularia, Rhynchosporium, Sporidesmium, Sporophagomyces and Thedgonia. Septocylindrium is reported from a wide range of hosts such as Bidens sp. (Asteraceae), Cerasus vulgaris (Rosaceae), Dryopteris carthusiana (Dryopteridaceae), Galanthus nivalis (Amaryllidaceae), Gossypium sp. (Malvaceae), Malus domestica (Rosaceae), Nicotiana tabacum (Solanaceae), Pyrus communis (Rosaceae), Sida acuta (Malvaceae) and Vitis (Vitaceae). Septocylindrium is reported from several countries including Asia (China, Japan, Russia), Europe (Bulgaria, Germany, Greece, Italy, Poland) and the United States (New York). An effort to re-collect and sequence species of Septocylindrium is needed.

 

Quarantine significance

Septocylindrium is in the list of quarantine pest for Europe (USDA, 2022).
