A new revision of the lichen genus <i>Pleopsidium</i> (Acarosporales, Acarosporaceae) in China reveals two new species.

ABSTRACT: Based on a combination of morphological, chemical, and phylogenetic analyses, we present a new revision of the lichen genus Pleopsidium in China. Pleopsidiumtumidulum sp. nov. and P.corrugatulum sp. nov. are proposed as new species to science, both included in a distinctive clade (clade 1) together with P.gobiense. These three species are characterized by the absence of fatty acids, acaranoic and acarenoic acids, and share similar ecological traits. In contrast, species containing fatty acids, including Pleopsidiumflavum, P.chlorophanum, and P.discurrens, constitute a separate clade (clade 2). Fresh specimens of Pleopsidiumdiscurrens were collected from the type locality, Yulong Snow Mountain, and molecular data were gen
