Based on morphological and chemical characters, we revised the taxonomy of Pleopsidium from China. Acarospora chlorophana, A. discurrens and A. gobiensis which belonged to genus Acarospora in An Enumeration of Lichens in China, were formally attributed to genus Pleopsidium, named Pleopsidium chlorophanum, P. discurrens and P. gobiense. In addition, P. flavum was increased. Now genus Pleopsidium from China has four species. The taxonomic descriptions and distribution of each species are given in details, and a key is presented.
