| Abstrakt: | In this study, two new species, Rhizoplacaadpressa Y. Y. Zhang & Li S. Wang and R.auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplacachrysoleuca -complex. Rhizoplacaadpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally non-constricted apothecia with orange discs that turn reddish-brown at maturity. Rhizoplacaauriculata is characterized by its squamulose to placodioid thallus, yellowish green and marginally pruinose squamules, wide (1-3 mm) and bluish-black free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally constricted apothecia with persistently orange discs. Rhizoplacaadpressa and R.auriculata share the same secondary metabolites of usnic and placodiolic acids. Competing Interests: The authors have declared that no competing interests exist.
