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.
