ABSTRACT A new species of Volvariella, collected from Aydın Province on the coast of the Aegean Sea in southwestern Turkey, is described as Volvariella turcica, sp. nov., based on morphology and multigene molecular analysis of three nuc rDNA gene regions: internal transcribed spacer ITS1-5.8S-ITS2 (ITS), 28S, and 18S. The new species was found in forests dominated by Pinus brutia and Quercus coccifera and mainly characterized by small basidiomata with a white pileus covered with pale ochre center and an ochre-discoloring volva, small basidiospores, lageniform pleurocystidia, balloon-shaped to clavate cheilocystidia, and stipitipellis hairs that are cylindrical or cylindrical-tortuous with subcapitate or lobe-like projections. A comprehensive description, illustrations, and line drawings are provided, and comparison with morphologically similar and phylogenetically related species is discussed.

土耳其新种 Volvariella turcica 及其多基因系统发育

摘要 从土耳其西南部爱琴海沿岸的 Aydın 省收集的一种新种 Volvariella，被描述为 Volvariella turcica，sp。11 月，基于三个 nuc rDNA 基因区域的形态学和多基因分子分析：内部转录间隔区 ITS1-5.8S-ITS2 (ITS)、28S 和 18S。该新种发现于以黑松和球果栎为主的森林中，主要特征为小型担子座，白色菌盖覆盖着淡赭色中心和赭色的草皮，小型担子孢子，lageniform pleurocystidia，气球状至棒状唇囊肿，和柱状或圆柱状弯曲的柱状体毛，具近头状或叶状突起。提供了全面的描述、插图和线条图，
