Kondratyuk et al. (2014) re-analyzed the phylogeny of the subfamily Xanthorioideae (Teloschistaceae) and introduced Scythioria as a new genus to accommodate the taxa Scythioria phlogina, which as the type species, based on ITS, LSU and mtSSU sequences. Kondratyuk et al. (2015) again described the species of Scythioria by transferring known species Caloplaca durietzii and C. flavogranulosa to Scythioria, based on ITS and LSU nrDNA and 12S SSU mtDNA sequences analyses. Currently, the genus Scythioria is characterized by crustose, areolate to endophloeic or endolithic, abundantly soredious, with or without anthraquinones thallus, paraplectenchymatous and usually poorly formed cortical layer, zeorine apothecia, and prosoplectenchymatous true exciple (Kondratyuk et al. 2014). Morphologically, Scythioria has a sorediate growth form, similar to that of the genus Leproplaca. Although the apothecial anatomy of Scythioria is similar to that of Flavoplaca, zeorine is usually present (Arup et al. 2013, Kondratyuk et al. 2014).
