K. austrostellaris K. jackii K. littoralis K. nubila K. orientalis K. tropica 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.

[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.

Apothecia are rare; when present, they are cup-shaped with a diameter of 1–2 mm and a brown, pruinose disc.
