摘　　要：在对海南省叶生地衣资源的调查研究中发现了中国肉盘衣属地衣新记录种:乳头肉盘衣[Fellhanera mastothallina (Vain.)Lücking&Sérus.],描述了其形态学、解剖学及化学特征,提供了显微结构照片。主要识别特征为:地衣体壳状,布满灰绿色乳头状颗粒,子囊盘棕色,囊盘被外部由疏丝组织构成,子囊孢子(3~)7隔,26~36μm×2~3μm,呈末端变窄的细棍棒状。基于线粒体小亚基(mtSSU)序列构建的系统发育树表明该种与本属模式种F. fuscatula (Müll. Arg.) Vězda具有较近的亲缘关系。编制了中国该属地衣的分种检索表。Fellhanera mastothallina(Vain.) Lücking & Sérus. was reported as a newly recorded species from China based on the foliicolous lichen specimens collected from Hainan Province. The characteristics of morphology, anatomy and chemistry were provided with microstructure photos. It was characterized by the crustose thallus with light green to orange-red verrucosa, brown apothecia, external exciple prosoplectenchymatous and narrowly clavate ascospores tapering towards proximal end,(3–)7-septate, 26–36 μm×2–3 μm.The phylogenetic tree based on the mtSSU region showed that it had close relationship with the type species F.fuscatula(Müll. Arg.) Vězda. A key to known Chinese Fellhanera species was also provided.
