Abstract: Hypocreopsis lichenoides (Tode: Fr.) Seaver is reported as new to Finland, and the records from Norway, Denmark, Sweden and the adjacent U.S.S.R. are surveyed. The species seems to be expanding rapidly in southern Fennoscandia, especially Sweden: the reasons for this development are discussed. New records are published from northern Quebec and Labrador, Canada. The species is briefly redescribed and compared with the allied H. rhododendri Thaxter, plus six other species of the genus. The ecological properties are discussed and a host list presented. H. lichenoides grows predominantly on species of Salix, followed by Corylus avellana, Prunus padus and Frangula alnus. In all, 21 angiosperm hosts and 3 gymnosperms are listed.
