Importance and distribution

There are 58 Wettsteinina epithets in Index Fungorum (2022), but several species have been transferred to Diadema, Didymella, Didymolepta, Dothiora, Extrawettsteinina, Kriegeriella, Leptosphaeria and Planistromella. Wettsteinina comprises 46 species known on a wide range of plants such as Arctagrostis latifolia (Poaceae), Bupleurum junceum (Apiaceae), Carex rostrata (Cyperaceae), Carissa spinarum (Apocynaceae), Cassiope tetragona (Ericaceae), Colpodium vahlianum (Poaceae), Coptis trifolia var. groenlandica (Ranunculaceae), Corylus avellana (Betulaceae), Phippsia algida (Poaceae), Poa sp. (Poaceae), Puccinellia angustata (Poaceae) and Selaginella stauntoniana (Selaginellaceae). Wettsteinina is reported from Asia (China, India, Russia), Australia, Europe (Austria, Denmark, France, Norway, Switzerland, United Kingdom) and North America (Canada, Greenland).
