Neoprotoparmelia amerisidiata

Neoprotoparmelia amerisidiata is a species of corticolous (bark dwelling) and crustose lichen in the family Parmeliaceae. Found in the southeastern United States, it was formally described as a new species in 2018 by Garima Singh and André Aptroot. The type specimen was collected by James Lendemer in the Sapelo Island Wildlife Management Area (Sapelo Island, Georgia); here the lichen was found growing on oak bark. It has a thin, shiny, pale olive-green to olive-grey thallus with numerous isidia. Secondary chemicals in the lichen that are detectable with thin-layer chromatography include alectoronic acid (major), and lesser to trace amounts of dehydroalectoronic acid and β-alectoronic acid. The specific epithet amerisidiata refers to both its North American distribution and the presence of isidia. It is known from North Carolina, Alabama, Georgia, Mississippi, and Florida.
