The current research is based on macrofungi collected from Ilgaz Mountain National Park and its environs between 2004 and 2008. As a result of field and laboratory studies, 220 taxa belonging to 59 families were identified. Nineteen taxa belong to Ascomycota and 201 to Basidiomycota. Three — Bisporella subpallida, Tricholoma bufonium, Leucogyrophana pseudomollusca — represent new records for Turkish mycobiota.
