Abstract: Geastrum berkeleyi Massee was found in NE Åland in 2004. The species has not been recorded earlier on Åland or in Finland. Several finds are known from the adjacent parts of Sweden, e.g. Uppland and especially Gotland. The species is rare in central and western Europe. The distribution of G. berkeleyi in the Nordic countries is briefly outlined and its ecology is discussed. The locality on Åland with the accompanying vascular plant flora and the soil properties is described. The properties which distinguish G. berkeleyi are discussed.
