摘　　要：本文通过形态学、解剖学、化学以及基于内转录间隔区(ITS)、核糖体大亚基(nuLSU)、线粒体小亚基(mtSSU)序列联合的系统发育学分析研究方法,确定鳞粉衣属Phyllobaeis一新种,即亚壳鳞粉衣P.subcrustacea。该种特征是地衣体壳状,有疣状突起;子囊盘浅红棕色至深棕色,圆饼状,盘面平坦或凹陷,盘缘明显;果柄不明显;侧丝单一或二叉分支;子囊长棒状,含8孢子,子囊顶器I–;子囊孢子卵圆形至纺锤形,无色,无隔或具1隔,I–。该种模式产自中国浙江。本文对该新种进行了表型描述并提供了特征照片,同时提供了鳞粉衣属已知物种检索表,为该属的生物多样性研究提供了基础资料。A new species of Phyllobaeis,P.subcrustacea,was identified by methods of morphology,anatomy,chemistry,and phylogenetic analysis based on combination of sequences of the internal transcriptional spacer(ITS),the large ribosome subunit(nuLSU),and the small mitochondrial subunit(mtSsU).It is characterized by the crustose thallus with clear schizidia;light reddish brown to dark brown apothecia with circinate,flat or sunken discs,obvious margin,unconspicuous podetia;simple or septate paraphyses;long-clavate asci,8-spored,with apex I–;ascospores are ovoid to fusiform,hyaline,simple or 1-septate,I–.The type specimen was produced in Zhejiang Province,China.In this paper,phenotypic description and characteristic photos of the new species are provided,and a key of known species of Phyllobaeis is also provided.
