Kondratyuk et al. (2014) proposed Yoshimuria (Teloschistaceae, Teloschistales, Lecanoromycetes) based on molecular, morphological, and anatomical characters, with the type species Yoshimuria spodoplaca. The type species was initially identified as Lecanora spodoplaca by Nylander (1890). Members of the genus Yoshimuria have the following morphological characteristics: thallus are crustose, continuous, from very thin to very thick and areolate, from whitish-gray to dark-gray or brownish-gray, anthraquinones. Apothecia are lecanorine or zeorine, sessile, disc yellow to orange or dark rust-brown; true exciple scleroplectenchymatous, subhymenium without oil droplets. Ascospores are polarilocular with 8-spored asci. Conidia are broadly bacilliform. Constituents: Anthraquinones of parietin chemosyndrome, as well as atranorin, are present in some species. The genus Yoshimuria is distinguished from the similar genus Orientophila by its mainly grey to very dark brownish grey thalli, scleroplectenchymatous true exciple, and broadly bacilliform conidia. Yoshimuria forms a separate clade within the subfamily Caloplacoideae (Kondratyuk et al. 2014). Some species of Yoshimuria (Yoshimuria cerussata and Yoshimuria stipitata) have been synonymized with Huea cerussata and Gyalolechia stipitata (Kondratyuk et al. 2019).
