First Report of Rhodocybe fumanellii (Entolomataceae) from Türkiye with Morphological and Molecular Characterisation

This study presents a comprehensive taxonomic assessment of fungal specimens collected from Çanakkale Province in northwestern Türkiye. An integrative approach was employed, combining detailed macro and micromorphological analyses with molecular phylogenetic methods based on the internal transcribed spacer (nrITS,rDNA) region of nuclear ribosomal DNA. The results confirmed the identity of the specimens as Rhodocybe fumanellii R.J. Ferrari, Vizzini & Fellin, representing the first record of this species in Türkiye. As a newly documented member of section Rufobrunnea, this finding broadens the known geographical distribution of the species and contributes to understanding the genus Rhodocybe in the region. The study includes thorough morphological descriptions, ecological data, precise locality information with geographic coordinates, collection details, and photographic documentation, thereby enriching the knowledge of fungal biodiversity in Türkiye.
