De Gruyter et al. (2013) introduced Subplenodomus with S. violicola (P. Syd.) Gruyter, Aveskamp & Verkley, as the type species, to accommodate selected phoma-like species that belong to Leptosphaeriaceae. Based on morphological and multi-gene phylogenetic analyses, Subplenodomus was accepted as an asexual morph of Leptosphaeriaceae (De Gruyter et al. 2013, Hyde et al. 2013, Ariyawansa et al. 2015b). Subplenodomus is characterized by thick-walled, ostiolate pycnidia, consisting of pseudoparenchymatous or sometimes scleroplectenchymatous cell types, phialidic, ampulliform to doliiform conidiogenous cells and hyaline, aseptate, and ellipsoid conidia (De Gruyter et al. 2013). Subplenodomus species formed two distant subclades in our phylogenetic analyses. Subplenodomus sensu stricto comprises S. galicola, S. violicola and our new species, S. meldolae, while S. apiicola (Kleb.) Gruyter, Aveskamp & Verkley, S. drobnjacensis (Bubák) Gruyter, Aveskamp & Verkley and S. valerianae (Henn.) Gruyter, Aveskamp & Verkley are grouped in Subplenodomus sensu lato. The genus comprises five species and here we introduce a new species from Italy. 

Type species: Subplenodomus violicola (P. Syd.) Gruyter, Aveskamp & Verkley, in Gruyter, Woudenberg, Aveskamp, Verkley, Groenewald & Crous, Stud. Mycol. 75: 23 (2012) [2013].

Other accepted species: Species Fungorum – search Subplenodomus.
