Parmelia pseudoshinanoana is a species of corticolous (bark-dwelling) foliose lichen in the family Parmeliaceae.[2] Described from Mount Fuji in 1951, this lichen is widespread across Japan, occurring on tree bark in temperate forests throughout Honshu and Shikoku. The species forms pale greenish- to brownish-grey rosette-shaped growths 6–12 cm across and is distinguished by its lobe edges that become densely covered with tiny upright projections and a continuous white rim of small pores—features that help separate it from the related P. shinanoana, which has simpler root-like structures and different chemistry.
Parmelia pseudoshinanoana was described by Yasuhiko Asahina in 1951 from the Omiya-guchi, 2-gōme route on Mount Fuji (Suruga Province).[3] In his 1987 Parmelia monograph, Mason Hale placed Parmelia laevior f. microphyllina Hue (1899; Japan[4]) in synonymy with this species. Asahina regarded P. pseudoshinanoana as a lobulate relative of P. shinanoana; both have a continuous, pale marginal band of pseudocyphellae, but P. shinanoana typically has mostly simple (unbranched) rhizines and a different chemistry (gyrophoric acid in the cortex).[5]
