Dothiorella Sacc. 1880

This genus of ascomycetes contains several hundred species, including a number of crop pathogens that cause canker, dieback and other diseases. For example, Dothiorella iberica, causes diseases on a variety of fruit and other trees like grapevine or avocado.

The genus is closely related to the genus Spencermartinsia (see Spencermartinsia viticola) and both genera cannot be separated morphologically. Both genera have 1-septate conidia that darken at an early stage of development, and have sexual morphs with brown, 1-septate ascospores (Phillips et al., 2013). Another closely related genus is Neofusicoccum. Sexual forms have been rarely observed.

Type species: Dothiorella pyrenophora
