摘要

Three Ramalina species having sublabriform soralia-R. pollinaria, R. sekika, and R. yasudae-were. revised morphologically, chemically, and molecular phylogenetically. These species are considered indistinguishable morphologically but distinguishable by their chemical and ecological habits. We found that soredium size was significantly different for each species. Molecular phylogenetic trees based on internal transcribed spacer regions of nuclear ribosomal DNA sequences showed that R. pollinaria is distantly related to R. yasudae and that R. sekika and R. yasudae together formed a monophyletic clade although the monophyly of R. yasudae could not be confirmed within the clade. These results suggest that R. pollinaria and R. yasudae should be treated as different species. Ramalina sekika could be treated as a chemical strain of R. yasudae according to the molecular phylogenetic result. However, we retain R. sekika and R. yasudae as distinct species because of the differences in soredium size, chemicalnature, distribution, ecological habit, and inadequate molecular information.

Yasudae的化学菌株。但是，由于钠大小，化学性质，分布，生态习性和分子信息不足，我们将R. sekika和R. yasudae保留为不同的物种。
