It is characterised by a yellow to greenish-yellow pileus with tiny scales in the center, yellowish lamellae, and is associated with Fagaceae. Based on phylogenetic analysis of the nuclear internal transcribed spacer (nrITS) sequences, the Turkish collection is placed in a well-supported clade along with its European representatives within the / Calochroi clade. Our results demonstrate the first distribution of this taxon outside the European continent and new to Türkiye. KW - Calochroi KW - ITS KW - Türkiye KW - Fungal taxonomy KW - Phylogeny N2 - Calonarius fulvocitrinus, morfolojik tanımlama ve moleküler kanıtlara dayanarak Türkiye'den ilk kez rapor edilmiştir. Ortada küçük pullu, sarı ila yeşilimsi sarı pileus ile sarı lameller ile karakterize edilmekte ve Fagaceae familyası ile ilişkilidir. Nükleer ribosomal iç transkribe ara parçası (nrITS) dizilerinin filogenetik analizine dayanarak, Türkiye’deki koleksiyonun, / Calochroi kladındaki Avrupa temsilcileriyle birlikte iyi desteklenen bir kladda yer almaktadır. Sonuçlarımız, bu taksonun Avrupa kıtası dışındaki ilk dağılımını ve Türkiye için yeni olduğunu göstermektedir. CR - Bellanger, J.-M. (2015).
