Abstract

The aim of the current study is to contribute to the knowledge of the genus Melanoleuca in Turkey. Delimitation of species taxonomic position within the genus is invaluable to protect the genus. Therefore, both morphological and molecular characters were used for identification of Melanoleuca specimens. Samples collected from Hakkâri province of Turkey were studied morphologically based on pileus, lamellae, stipe, spore, basidia and cystidia structures. Then, DNA sequence data of the Internal Transcribed Spacer (ITS), the Large Subunit (LSU) of the nuclear ribosomal RNA (rRNA) gene complex and Translation Elongation Factor 1-α (TEF) regions were analysed to figure out phylogenetic positions within the genus. At the end of the study, two new records species of Melanoleuca (M. communis and M. dryophila) were reported from Hakkâri province. When ITS and LSU regions were analyzed, M. communis placed within subgenus Melanoleuca / section Melanoleuca and M. dryophila placed within subgenus Urticocytis / section Grammopodiae. Considering the lack of information of this genus in Turkey and the fact that no detailed study has been developed before, this work is valuable to the systematics of Melanoleuca and to the taxonomic knowledge of agarics in Turkey
