Abstract Rinodina peloleuca (Physciaceae) is an
austral, maritime lichen species occurring in Tasmania and New Zealand, in
southern South America, on subantarctic islands, and in maritime Antarctica.
Together with other species, it indicates an austral connection in maritime
lichens of the Southern Hemisphere. Chemically, the species is characterised by
the presence of skyrin and triterpenes.
Rinodina antarctica,
R. deceptionis,
R. endochrysodes,
R.
philomelensis, and, possibly,
R. aspicilina are synonyms
of
R. peloleuca. The lichenicolous fungi
Muellerella
lichenicola,
Polycoccum sp.,
Pyrenidium actinellum, and an
unidentified coelomycete occur on the species.
