Peltigera papuana

Species of lichenised fungus

Peltigera papuana is a lichen-forming fungus in the family Peltigeraceae. It was described in 2009 from Madang Province of Papua New Guinea, which inspired its specific epithet. Genetic analysis of both the mycobiont and the photobiont, which is a Nostoc cyanobacterium, suggests that the evolutionary origin of Pelitgera papuana is from an ancient dispersal event from South America, although this remains inconclusive.
