Kondratyuk et al. (2014) introduced Verrucoplaca as a new genus by re-analyzed the phylogeny of the subfamily Xanthorioideae (Teloschistaceae) to accommodate the taxa Verrucoplaca verruculifera as the type species, based on phylogenetic analyses of combined ITS, LSU and mtSSU sequences. To date, the new genus comprises only a single species, a widely distributed species found in coastal rocks (Søchting 1973, Arup 1995, Wetmore & Kärnefelt 1998, Kondratyuk et al. 2014). The genus is characterized by rosette-like, lobate, anthraquinone thallus, palisade plectenchymatous cortical layer, zeorine apothecia, inspersed by oil droplets subhymenium, true exciple of Verrucoplaca-type, and narrowly ellipsoid conidia (Kondratyuk et al. 2014).

Type species: Verrucoplaca verruculifera (Vain.) S.Y. Kondr., Kärnefelt, Elix, A. Thell, J. Kim, M.-H. Jeong, N.N. Yu, A.S. Kondratiuk & J.S. Hur

Other accepted species: This genus is monotypic.
