Abstract

Tuber magnatum Picco, the Italian white truffle mushroom recorded for the first time in Türkiye, is a rare and economically valuable mushroom. Samples were collected from Sakarya province during field studies in 2024. The samples were identified as T. magnatum according to their macro- and microscopic features. To make molecular confirmation of the species, the samples' ITS1 and ITS4 gene regions were analysed and registered in Genbank with the number PP239641. The sample showed 100% compatibility with other T. magnatum accessions in Genbank. The distributions of Tuber species in Türkiye were given, and their taxonomic features were compared.
