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 (

The lichen has a

. 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''.
