The growing demand for truffles has led to a global pursuit for their occurrence in the wild, and studies concerning their cultivation. Although European countries such as Italy, France and Spain have been known for truffle production, truffle hunting is new to Finland. The present study reports for the first time, the findings of Tuber maculatum in Finland on the basis of morphological and molecular analysis. The chemical characteristics of soil samples collected from the truffle sites have also been discussed. The species of the Tuber samples were identified primarily using morphological analysis. Molecular analysis was carried out for the confirmation of the identity of the species. Two phylogenetic trees were constructed based on internal transcribed spacer (ITS) sequences produced in this study and including representative sequences of whitish truffles available in GenBank. The truffles were identified as T. maculatum and T. anniae . This study could be considered as a basis for encouraging research on findings and identification of truffles in Finland.
