NotesUleodothis was originally positioned in Dothioraceae (Dothideales) by Stevens (1920). Later, Müller & von Arx (1962) established this in Mycosphaerellaceae (Pseudosphaeriales) and Luttrell (1973) referred it to Venturiaceae (Venturiales). Zhang et al. (2011) treated it as a genus in Dothideomycetes incertae sedis. Uleodothis and Plowrightia have similar characters such as semi-immersed, multi-loculate, pulvinate, dark brown to black ascostromata and 1-septate ascospores. However, Plowrightia has thick-walled locules which develop in the upper stroma, lacking pseudoparaphyses, and ascospores which are constricted at the septum (Thambugala et al. 2014a, Hyde et al. 2018). Uleodothis has thin-walled locules which develop in middle of stroma, persistent pseudoparaphyses and ascospores slightly constricted at the septum or without septation (Theissen & Sydow 1915, Hyde et al. 2018). Also, Uleodothis has some similar morphological characters to Aplosporella (Aplosporellaceae, Botryosphaeriales) (Hyde et al. 2018). Hyde et al. (2018) re-examined the type specimen of Uleodothis and accepted Uleodothis in Dothideaceae as a sister genus to Plowrightia based on only morphological evidence. Fresh collections and sequence data related to Plowrightia and uleodothis-like taxa are required to further clarify their phylogenetic relationships.
