About Flavopunctelia soredica (Nyl.) Hale
Flavopunctelia soredica is a foliose lichen species that belongs to the family Parmeliaceae. It was first formally described under the name Parmelia soredica by Finnish botanist William Nylander in 1872. In 1982, Hildur Krog moved this species into the subgenus Flavopunctelia of the newly circumscribed genus Punctelia, which Krog created to group Parmelia species that have punctate, point-like pseudocyphellae. A few years after this transfer, Mason Hale elevated the subgenus Flavopunctelia to the status of a full independent genus. This lichen has the common name powder-edged speckled greenshield. It has a wide distribution, and has been recorded growing in North America, South America, South Africa, India, Russia, China, and Japan.
