摘　　要：茶薪菇是我国广泛栽培的一种食药用菌,由于其形态特征与柱状环伞十分相似,分类地位至今尚不明确。本研究采用形态学和多基因分子系统发育分析相结合的方法,研究茶薪菇和柱状环伞的分类问题,结果表明:茶薪菇和柱状环伞是两个不同但亲缘关系密切的物种;在形态上,茶薪菇菌盖颜色浅褐色至深褐色,油茶味浓,菌环较薄易脱落,褶缘囊状体柱状、烧瓶状或纺锤状,易与柱状环伞相区别。因此,提出了该种新组合——茶薪菇Cyclocybe chaxingu,并指定了茶薪菇的新模式(凭证标本为HFJAU1332,保存于江西农业大学真菌标本馆)。Chaxingu,formerly named as Agrocybe chaxingu,is an edible and medicinal mushroom widely cultivated in China.Its taxonomic identity is still ambiguous due to morphological similarity to Cyclocybe cylindracea.In this study,morphological characteristics and multiple genes’phylogenetic evidence were employed to delimit the species.Our data indicated that A.chaxingu and C.cylindracea are two different but closely related species.Morphologically,A.chaxingu differs from C.cylindracea by its light brown to dark brown pileus with strongly oiltea camellia flavor,thin and easily broken annulus,and cylindrical to lageniform or cambiform cheilocystidia.A new combination,Cyclocybe chaxingu was proposed,and a neotype was designated(HFJAU1332,deposited at Herbarium of Jiangxi Agricultural University).
