Notes – Preuss (1851) introduced Plenodomus typified by P. rabenhorstii. Due to the loss of the holotype specimens, Boerema & Kesteren (1964) designed P. lingam as the type species of Plenodomus. The genus is saprobic or parasitic on stems and leaves of various plants in terrestrial habitats and is remarkable in having immersed ascomata with scleroplectenchyma cell types of peridium, and 3-5-distoseptate, broadly fusiform ascospores. The classification of Plenodomus was revisited by de Gruyter et al. (2013) and was followed by Ariyawansa et al. (2015b), Marin-Felix et al. (2017), Tennakoon et al. (2017) and Phookamsak et al. (2019).
