Saprobic or parasitic on stems and leaves of herbaceous or woody plants in terrestrial habitats. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, globose to papillate, or with an elongate neck, solitary or aggregated, thin-walled pseudoparenchymatous, or thick-walled scleroplectenchymatous, ostiolate, unilocular.

Type species: Subplenodomus violicola (P. Syd.) Gruyter, Aveskamp & Verkley
Notes: Subplenodomus is characterised by pycnidial, globose to papillate conidiomata, phialidic, ampulliform to doliiform conidiogenous cells and hyaline, aseptate, ellipsoid to cylindrical conidia. Subplenodomus resembles Plenodomus in having thick-walled conidiomata with pseudoparenchymatous peridium while Plenodomus has scleroplectenchymatous peridium (De Gruyter et al. 2013). All species of Subplenodomus have conidiomata with an elongated neck, like members of Plenodomus while S. drobnjacensis has conidiomata with scleroplectenchymatous walls. Several authors added new species to Subplenodomus (Tibpromma et al. 2017; Pem et al. 2020). Molecular markers available for Subplenodomus include LSU, SSU, ITS, Actin and BTUB.
