Kashiwadia is a genus of lichen-forming fungi in the family Physciaceae.[1] The genus was circumscribed in Sergey Kondratyuk, László Lőkös, and Jae-Seoun Hur in 2014 to contain the species Physcia orientalis, after molecular phylogenetic analysis showed that the taxon occupied an isolated phylogenetic position in the Physciaceae.[2] An additional five species were added to the genus in 2021.[3] The genus name honours Japanese lichenologist Hiroyuki Kashiwadani, who originally described the type species.[2]

Kashiwadia species are foliose (leafy) and whitish-grey, with lobes measuring 1–2.5 mm wide. The upper surface of the thallus is smooth, convex, and lacks pruina, while the lower surface is pale to brownish. Apothecia are rare; when present, they are cup-shaped with a diameter of 1–2 mm and a brown, pruinose disc. Both atranorin and zeorin are lichen products found in the genus.[2]
