  • Thell, A./ Tsurykau, A./ Persson, P.-R./ Hansson, M./ Åsegård, E./ Kärnefelt, I./ Seaward, M.R.D. 2017: Parmelia ernstiae, P. serrana and P. submontana, three species increasing in the Nordic countries. - Graphis Scripta 29(1-2): 24-32. [RLL List # 247 / Rec.# 38827]
    Abstract: Revised information on the morphology, chemistry and distribution of species of Parmelia s. str. in Fennoscandia is presented. Although Parmelia ernstiae was earlier believed to be chemically distinct from P. serrana in terms of lobaric acid, its presence in all studied samples detected by TLC means that these two semi-cryptic species can no longer be chemically separated. All three species are increasing in frequency and spreading northwards in Fennoscandia. Parmelia serrana is reported as new to Zealand in Denmark.
