Pannaria emodii is a species of corticolous (bark-dwelling), squamulose (scaley) to foliose (leafy) lichen in the family Pannariaceae. It was formally described as a new species in 2001 by the Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected in 1967 by Hiroshi Harada and colleagues from Shodu-Barshong (Bhutan) at an altitude between .
The lichen has a rosette-shaped thallus up to in diameter with peripheral up to about 3 mm wide. Its are simple (i.e., without any septa), more or less spherical and colourless, and measure 10âÂÂ12 by 6âÂÂ8 üm. The thallus does not show any reactions to standard chemical spot tests, and no lichen products were detected using thin-layer chromatography. Pannaria emodii is found in the eastern Himalayas with a geographic range extending from Bhutan to Sichuan, China. In India, Pannaria emodii often associates with moss genus Hyophila.
