Barr (1972) synonymized Plowrightia under Dothiora. However, Plowrightia is different from Dothiora based on the pulvinate, erumpent ascostromata, with small locules which height is greater than width (Thambugala et al. 2014a). Phylogetic analyses indicated that Plowrightia is a member of Dothideaceae (Winton et al. 2007, Thambugala et al. 2014a). Theissen & Sydow (1915) synonymized Plowrightia balansiana, P. rhynchosporae, and Polystomella aphanes under Uleodothis based on morpholocal similarity. Plowrightia and Uleodothis are similar in ascostromatal and ascospore characters (Hyde et al. 2018). In our phylogenetic analyses, Plowrightia abietis is grouped with Rhizosphaera oudemansii (92 % ML, 1.0 PP). Therefore, we agree with the conclusion of Thambugala et al. (2014a) that Plowrightia abietis and R. oudemansii are identical with the latter as the asexual morph of P. abietis. Plowrightia periclymeni formed a separate lineage with P. abietis, Rhizosphaera kalkhoffii and R. oudemansii (0.97 PP). In our study, we place Plowrightia as a genus in Dothideaceae. However, more collections and sequence data are needed to confirm its taxonomic placement.
