Volvariella pilosipilea (Volvariellaceae, Agaricales): A new record for Türkiye mycobiota

Volvariella is a cosmopolitan genus, with V. pilosipilea recently described from Spain following a revision of the European taxa. This study reports the first record of Volvariella pilosipilea from Western Eurasia (Adıyaman Province, Türkiye), thereby extending its known distribution beyond the type locality. The identity of the studied collection was confirmed through a combination of morphological features and molecular phylogenetic analysis based on the nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) region. We provide a detailed morphological description of the species, photographs of the basidiomata, line drawings of key microscopic structures, and a phylogenetic tree to illustrate its placement.
