Taiwania

A novel species and a new record of genus Descolea from Indian Himalaya Descolea indoquercina sp. nov. from India is described and illustrated based on morphological and phylogenetic inference. It is characterized by medium to large basidiomata, dark olivaceous brown to dark brown, convex to plano-convex pileus with warts on surface; amygdaliform to limoniform, coarsely verrucose basidiospores, presence of pleuromacrocystidia and hymeniform type of pileipellis. In addition, D. flavoannulata (Lj. N. Vassiljeva) E. Horak is reported and described first time from India in the present communication. Both taxa are presented with detailed descriptions, field and microscopic photographs, illustrations, SEM images of basidiospores, nrITS based molecular phylogeny and comparisons with similar species.

描述了一种新的物种及属 Descolea 的新记录，源自印度喜马拉雅山脉。基于形态学和系统发育推断，新物种 Descolea indoquercina sp. nov. 从印度被描述并绘图。该物种以中等至较大的菌盖、暗橄榄褐色至深褐色、凸形至扁凸形的子实体表面有疣点；杏仁形至柠檬形、粗糙的疣状担孢子；以及存在横隔大型囊菌和菌盖皮层为菌幕型为特征。此外，D. flavoannulata (Lj. N. Vassiljeva) E. Horak 首次从印度报道并描述。两种分类群均提供了详细的描述、野外及显微照片、插图、担孢子的扫描电子显微镜图像、基于 nrITS 的分子系统发育和与相似物种的比较。
