摘　　要：拟蜡伞属Hygrophoropsis是牛肝菌目中的一个小属,现归属于独立的科——拟蜡伞科。本研究从形态学特征、分子生物学证据、生态学和地理分布等方面描述了一种可食用的新种——芦苇拟蜡伞。该新种的特征为菌盖表面乳白色至淡赭色;菌褶白到奶油色;担孢子长圆形至椭圆形,厚壁,具轻微糊精反应,大小为6–10×4–5.5μm,生长在我国北方芦苇上。基于ITS和nrLSU序列的系统发育分析,表明该新种在拟蜡伞属的系统发育地位,并讨论了新种与其近缘种的鉴别特征。Hygrophoropsis is a small genus in Hygrophoropsidaceae of Boletales.A new and edible species,H.phragmiticola,is described based on morphological characteristics,molecular evidence,ecology and geographic distribution.The new species is characterized by creamy-whitish to pale-ochraceous pileal surface,white to cream gills,oblong or ellipsoid,thick-walled,weakly dextrinoid basidiospores measuring 6–10×4–5.5μm,and growing on Phragmites species in northern China.Molecular analysis based on ITS and nrLSU sequences demonstrates the phylogenetic position of the new species in Hygrophoropsis.The new species and its closely related species are compared and discussed.
