Polycauliona polycarpa
Polycauliona polycarpa is a species of corticolous, foliose lichen in the family Teloschistaceae. It was first formally described by German botanist Georg [Franz Hoffmann] in 1796, as Lobaria polycarpa. It has acquired quite an extensive synonymy in its taxonomic history. In 2013, Patrik Frödén and colleagues transferred it to the genus Polycauliona, as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae. In northern North America, one vernacular name for the species is pin-cushion sunburst lichen.
