Pannaria ramulosa

Pannaria ramulosa is a species of corticolous, squamulose to foliose lichen in the family Pannariaceae. It was formally described as a new species in 2001 by the Norwegian lichenologist Per Magnus Jørgensen. Gustaf Einar Du Rietz collected the type specimen in 1927 from the Goenoeng Ardjoena. This rainforest lichen has a rounded thallus up to in diameter with thin, brownish. It does not show any reactions to standard chemical spot tests, and no lichen products were detected using thin-layer chromatography. At the time of its original publication it was only known to occur at the type locality.
