Xanthoria elegans (Link) Th.Fr., with narrow and convex lobes, in contrast to wide and plane thalline
lobes of Xanthoria parietina (L.) Th.Fr. was recognized at the end of the 18 th century. The X. elegans group
including 12 species was segregated from the genus Xanthoria as a separate genus, Rusavskia S. Y. Kondr.
& Kärnefelt, in 2003 based on morphological and anatomical data (Kondratyuk & Kärnefelt 2003). Later it was
shown that the Rusavskia elegans group including R. elegans (Link) S.Y. Kondr. & Kärnefelt, R. sorediata (Vain.)
S.Y. Kondr. & Kärnefelt, R. papillifera (Vain.) S.Y. Kondr. & Kärnefelt and R. digitata (S.Y. Kondr.) S.Y. Kondr.
& Kärnefelt, forms a robust monophyletic branch in the family Teloschistaceae according to molecular data
(Fedorenko et al., 2009, 2011). Rusavskia elegans is frequently misidentified, and even gene bank sequences
ascribed to R. elegans in fact belong to the Caloplaca saxicola group. About ten morphologically similar to R.
elegans lichen groups shown to form separate robust monophyletic branches in the phylogenetic tree of the
Teloschistaceae (Kondratyuk et al. in prep.). Among them there are the following: Rusavskia resendei (Poelt)
S.Y. Kondr. & Kärnefelt, showing also similarity to Xanthoria parietina group, as well as the gasparrinioid (=placodioid)
species groups Caloplaca saxicola, C. regalis, C. aurantia, C. trachyphylla, C. elegantissima etc. Results
of phylogenetic analyses based on nuclear and mitochondrial DNA, and new morphological and anatomical
data, on groups mentioned above will be illustrated. Their taxonomic status will be especially discussed. New
Asian species of the Rusavskia elegans group and closely related groups of gasparrinioid lichens, i.e. C. trachyphylla
(Tuck.) Zahlbr., C. mogoltanica S.Y. Kondr. & Kudratov, C. scrobiculata H. Magn.), as well as taxa of C.
persica (J. Steiner) M. Steiner & Poelt and C. intrudens H. Magn. groups will be presented. Financial support of
the State Agency on Science, Innovation and Information of Ukraine (417/2011) is appreciated.
