Notes – Dothidotthia is the type genus of Dothidotthiaceae and is typified by Dothidotthia symphoricarpi (Phillips et al. 2008). The asexual morph of Dothidotthia is linked to Thyrostroma (Ramaley 2005, Phillips et al. 2008). Molecular studies showed that Thyrostroma compactum (type species) forms a distinct clade within Dothidotthiaceae, and forms a separate clade to Dothidotthia symphoricarpi, which suggests that they are not congeneric (Crous et al. 2016b, Marin-Felix et al. 2017). This suggestion was confirmed by Senwanna et al. (2019) with the use of molecular data, along with morphology.
