摘　　要：秦岭地区生物多样性丰富,存在许多亟待开发的大型真菌资源。描述了1种来自秦岭的拟蜡伞属大型真菌新种——宁陕拟蜡伞Hygrophoropsis ningshanica。形态特征结合系统发育分析结果表明,该物种属于橙黄拟蜡伞复合群。该新种的主要特征:子实体呈橙黄色,菌褶延生,担孢子椭圆形至长椭圆形,大小为5.5~6.5×3.5~4.0μm,非淀粉质。进行了采自秦岭拟蜡伞新种的ITS和LSU序列系统发育分析,提供了新种的照片与描述,并讨论了新种与相似物种的鉴别特征。The Qinling Mountains in China is well known to have rich biodiversity where a lot of macrofungi resources are remaining to be exploited.In this study,a new macrofungi species growing in Qinling Mountains from genus Hygrophoropsis,named as the H.ningshanica,is descripted in detail.Morphological characterization combining with the phylogenetic analysis indicate that H.ningshanica belongs to the H.aurantiaca complex.The new species reveals its characteristics of fruiting body fully in orange color,decurrent gills and basidiospores in shapes of ellipsoid or long ellipsoid with a size of 5.5-6.5×3.5-4.0μm but without reactions to the dextrin.Results from phylogenetic analyses using ITS and LSU sequences and scientific pictures revealing its morphological characteristics of H.ningshanica are presented within the paper.Discussions on the features of new species differing from its similar species are also carried out.
