First record of Pluteus tenebromarginatus (Pluteaceae, Agaricomycetes) from Türkiye, outside its type locality

OpenAlex İngilizce

The genus Pluteus exhibits a cosmopolitan distribution. Pluteus tenebromarginatus, which is a member of Pluteus section Celluloderma, has been recently described from its type locality in France. The present study reports the first record of P. tenebromarginatus from Western Eurasia, based on collections from Burdur Province, Türkiye. This finding significantly extends the known distribution of the species beyond its originally described range. The identity of the Turkish specimens was established through an integrative approach, combining detailed macro- and micromorphological analyses with molecular phylogenetic inference based on the nuclear ribosomal internal transcribed spacer (ITS) region. A comprehensive morphological description is provided, supplemented by photographs of the basidiomata and pictures of diagnostic microscopic features. In addition, a phylogenetic tree is presented to confirm the placement of the specimen within the genus.
