Bottom Line: However, there currently has been no revisional study performed until now.To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences.This study also presents a detailed description of each species and a key to the genus.

ABSTRACT
In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences. A thorough examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) confirmed that eight species of Xanthoparmelia occur inside South Korea. Our analysis further confirmed the colors of the lower surface and medullar chemistry are important taxonomic characters in Xanthoparmelia. This study also presents a detailed description of each species and a key to the genus.

Maximum parsimony tree of 8 species of Xanthoparmelia in Korea; Lecanora muralis and Flavoparmelia caperata as outgroups. Data matrix has 10 taxa and 40 characters. All characters are of 'unord' type and have equal weight. Character 6 is constant, 11 variable characters are parsimony-uninformative, number of parsimony-informative characters = 23. Tree length = 58, Consistency index (CI) = 0.59, Homoplasy index (HI) = 0.41.

Tree length = 58, Consistency index (CI) = 0.59, Homoplasy index (HI) = 0.41.

Mentions: A maximum parsimony tree was performed using PAUP (Swofford, 2002) (Fig. 1) for the phenotypic analysis of Xanthoparmelia. Within the Xanthoparmelia clade, the species can be separated into two groups that indicate the color of the lower surface is the most important phenotypic character to distinguish between the species. Group I was characterized by a dark brown to black lower surface while the lower surface of group II was characterized by a pale brown color.
