【摘要】 通过对鳞网衣属地衣形态和化学的研究,并结合核基因ITS序列的系统发育分析,报道了采自中国秦岭山区鳞网衣属1中国新记录种——球鳞网衣(新拟)[Psora globifera(Ach.)A.Massal.]。其识别特征为地衣体由密集、重叠鳞片组成,边缘常上翘,具有光泽,无粉霜,老鳞片上表面常具裂纹;子囊盘微凸至半球形,单一或数个簇生。该研究提供了该种基于中国标本的详细描述,并与相似种进行了比较。更多还原

【Abstract】 Psora globifera(Ach.)A.Massal.is reported new to China based on the specimens collected from Qinling Mountains of Central China.The morphological and chemical analysis,and a phylogenetic analysis of nrDNA ITS sequence were carried out.The new record species can be distinguished by its shiny and epruinose,crowded and overlapping squamules with upturned margins,fissures in older squamules;and apothecia slightly convex to hemispherical,borne singly or in clusters on the surface of thallus.Detailed description and discussion with allied species were provided.更多还原
