Importance and distribution

Selenophoma species are plant pathogens causing halo spot of grasses and cereals (Kalani 1964). There are 98 Selenophoma epithets in Index Fungorum (2022), but several species have been transferred to other genera such as Excipula, Mycosphaerella, Phyllosticta, Pseudoseptoria, Pseudosydowia, Selenophoma, and Sydowia. Selenophoma comprises 83 species known on a wide range of plants such as Alhagi sp. (Fabaceae), Ammothamnus lehmannii (Fabaceae), Arenaria sp. (Caryophyllaceae), Aristida (Poaceae), Aster tripolium (Asteraceae), Bromus (Poaceae), Bupleurum sp. (Apiaceae), Buxus sempervirens (Buxaceae), Capparis spinose (Capparaceae), Catananche caerulea (Asteraceae), Crithmum maritimum (Apiaceae), Elymus nutans (Poaceae), Erigeron monticolus (Asteraceae), Eucalyptus mineata (Myrtaceae), Foeniculum vulgare (Apiaceae), Roegneria hirsuta (Poaceae), and Sorghum vulgare (Poaceae). Selenophoma has a wide geographical distribution including Africa (Algeria), Asia (China, Uzbekistan), Australia, Europe (Germany, Greece, Italy, United Kingdom), North America (Canada, the The United States) and Union of Soviet Socialist Republics (USSR).

 

Quarantine significance

Selenophoma is of quarantine importance as it causes leaf spot, speckle, blotch, or eye spot on smooth bromegrass on Bromus species.
