The genus was
circumscribed in 2013 by lichenologists Ulf Arup, Ulrik Søchting, and Patrik Frödén as part of a
molecular phylogenetics-led major restructuring of the Teloschistaceae. It was segregated from the large genus Caloplaca, which was shown by several prior studies to be
polyphyletic. The authors assigned Orientophila subscopularis as the
type species. The genus name, which means "fond of the east", refers to the East Asian distribution of its species. Orientophila is in the subfamily Xanthorioideae of the family Teloschistaceae.[3]
Description
The thalli of Orientophila species have a crust-like appearance that can be either smooth or slightly lobed. Chemically, it contains compounds called
anthraquinones. Its outer protective layer, or
cortex, has a
paraplectenchymatous tissue structure. The reproductive structures, or
apothecia, are of the
zeorine type and also contain anthraquinones. The spores produced by this genus are
polardiblastic (typical for the family Teloschistaceae), and have a medium to long dividing line known as a
septum. Structures called
pycnidia, which are involved in asexual reproduction, have not been observed in this genus.[3]
