NotesThyrostroma was introduced by Höhnel (1911). Ramaley (2005) and Phillips et al. (2008) considered Thyrostroma as the asexual morph of Dothidotthia. However, phylogenetic analyses demonstrated that Thyrostroma and Dothidotthia are not congeneric (Crous et al. 2016b, Marin-Felix et al. 2017, Senwanna et al. 2019). Therefore, Senwanna et al. (2019) segregated Thyrostroma from Dothidotthia based on morphological and molecular evidence.
