Abstract Aspicilia fluviatilis and A. granulosa , two arctic and/or (sub)alpine species with elongate ± diverging and ± branching marginal areoles, are described as new and compared with similar species occurring in Fennoscandia. A parsimony analysis based on ITS indicates a close relationship with the mainly coastal A. epiglypta . Aspicilia epiglypta , A. disserpens and A. sublapponica are lectotypified and A. disserpens is reduced to synonymy with A. perradiata . Aspicilia alboradiata and A. circularis are excluded from the Fennoscandian lichen biota. A key to Fennoscandian Aspicilia species with radiating thalli and/or elongate ± diverging and ± branching marginal areoles is also presented.
