2.2.12 Stigmatodiscales ( Dothideomycetes, Ascomycota)

Asterodiscus tamaricis was introduced by Voglmayr et al. (2016) from material collected on dead twigs of Tamarix tetrandra (Austria) but later transferred to Stigmatodiscus, S. tamaricis, by Voglmayr and Amengual (2018). A second species, Asterodiscus mangrovei was described by Dayarathne et al. (2020a) from decaying submerged wood at a mangrove strand in Thailand. Voglmayr et al. (2016) referred Stigmatodiscus to the new family and order ( Stigmatodiscaceae, Stigmatodiscales) and recorded for the first time for the marine fungi checklist. In the present study, we transfer Asterodiscus mangrovei to Stigmatodiscus as S. mangrovei .
