Abstract: The immigration and establishment of Albatrellus syringae (Parmasto) Pouzar in Estonia, Finland, Sweden and Norway since it first appeared in 1901 is explained. The species is shown to be an example of a spontaneously expanding fungus in Fennoscandia, rising from anonymity in the first half of the 1900s to be annually recorded from new localities during the last three decades. It is now distributed in a majority of the provinces in each of the treated countries. Ecologically six different types of habitats have been recognized. In general the species profits by diverse ruderal sites, but is also found in undisturbed forest habitats. Its association with different woody species, including lilac (Syringa), appears purely accidental, and the fungus is stated to be a saprobe, perhaps also a root necrotroph. The history of dispersal of A. syringae in Fennoscandia and the Baltic region the past century is illustrated by distribution maps for consecutive periods.
