红脐鳞种群界定的综合研究

摘要

对于以表面色泽与化学成分为根据从红脐鳞种内分出褐脐鳞作为另一独立种的综合性状进行了比较研究.该研究是以干标本及活菌培养的形态学、化学及分子数据为基础进行的.研究结果并不支持褐脐鳞作为独立种级单位的存在,而被作为红脐鳞种下的化学型予以订正.%The comparative studies of Rhizoplaca fumida and Rh. chrysoleuca based on morphological, chemical and genetic data showed that the different upper surface colour of thallus and containing or lacking usnic acid in the thalli can not be regarded as the evidence for specific demarcation. These characters do not support Rh. fumida as a separate species, which can be treated as one of the chemotypes within Rh. chrysoleuca.
