Ramboldiaceae was introduced by Miądlikowska et al. (2014) to accommodate Ramboldia as the type genus in the suborder Lecanorineae (Lecanorales, Lecanoromycetidae). Initially, Ramboldia was introduced by Kantvilas and Elix (1994) to include five species of saxicolous, lignicolous or corticolous of lecideoid crustose lichens. Ramboldiaceae species are characterized in having lecideoid apothecia with an unpigmented (in some species pigmented apothecia occur due to the presence of russulone and related anthraquinones) prosoplectenchymatous exciple, a Lecanora-type asci, sparsely branched and anastomosing paraphyses, and simple, hyaline, non-halonate ascospores (Kantvilas & Elix 1994, Miądlikowska et al. 2014, Kantvilas 2016). The asexual morph is coelomycetous (Kantvilas 2016). Currently, only the genus type is accepted by this family (Wijayawardene et al. 2020). The nuclear SSU, LSU, mtSSU and RPB2 molecular markers were used to elucidate the phylogenetic position of this family (Miądlikowska et al. 2014).
