Importance and distribution
Species of Dothidea are saprobic and helps in decomposition of organic matter in the ecosystem. Even though there are 385 Dothidea epithets in Index Fungorum (2022), several species have been synonymized and transferred to other genera such as Asteroma, Camarotella, Coleroa, Cryptophyllachora, Cycloschizon, Fusoidiella, Lecanosticta, Leveillina, Melanops, Microcyclus, Mycosphaerella, Omphalospora, Phyllachora, Piggotia, Rhytisma, Stigmatula, Synchytrium and Vizella. Dothidea comprises 33 species known on host plants such as Aloe sp. (Asphodelaceae), Anthurium sp. (Araceae), Berberis sp. (Berberidaceae), Bigelovia sp. (Rubiaceae), Ficus sp. (leaf spot) (Moraceae), Juniperus sp. (Cupressaceae), Maytenus magellanica (Celastraceae), Phragmites australis (Poaceae), Poa sp. (On leaves.) (Poaceae), Prunus sp. (Rosaceae). Dothidea is reported from several countries including Africa (Eritrea), Asia (Pakistan), Australia, Europe (Ukraine), South America (Argentina, Colombia) and the United States (Montana, New Jersey, South Carolina). Dothidea has high diversity but several species lack sequence data and requires revision.
