摘　　要：报道了采自中国秦岭地区的2个马鞍菌属新种,即长柄马鞍菌Helvella longipes和太白马鞍菌Helvella taibaiensis。长柄马鞍菌菌盖呈盘状或杯状,浅灰褐色至黑褐色带有黑色斑点,菌柄长2.5~11.0 cm,表面平滑无棱脊;太白马鞍菌菌盖呈盘状或杯状,颜色较均匀,呈烟灰色,菌柄长2.0~3.5 cm,表面平滑无棱脊。提供了2个新种标本宏观和微观特征的详细描述,以及基于其ITS和LSU序列进行的系统发育分析,并讨论了新种与相似物种的鉴别特征。This paper reports two new species of the genus Helvella,Helvella longipes and Helvella taibaiensis,discovered from the Qinling Mountains in China.H.longipes is characterized by its discoid or cup-shaped pileus in a pale and drab-gray to blackish brown color with black spots,showing a smooth surface without ribs and a 2.5-11.0 cm long stipe.H.taibaiensis carries its morphological features also revealing a discoid or cup-shaped pileus but in a uniformly smoke gray color,a smooth surface without ribs and a 2.0-3.5 cm long stipe.Macroscopic and microscopic descriptions of these two new species are provided in detail.Results derived from the phylogenetic analyses by using ITS and LSU sequences along with discussions upon how to distinguish the new species from other similar but different kinds of species by knowing their special characteristics are also given.
