Three genera new for science, i.e. Candelinella S. Y. Kondr. for the Candelariella makarevichiae group, Opeltiella S. Y. Kondr. for the Candelaria fraudans group, as well as Protocandelariella Poelt, D. Liu, J.-S. Hur et S. Y. Kondr. for the Candelariella subdeflexa group are proposed for robust monophyletic branches of the Candelariaceae on the basis of three-gene phylo- geny (i.e. concatenated nrITS, 12S mtSSU and 28S nrLSU sequences). Eight new combinations, i.e. Candelinella makarevichiae (for Candelariella makarevichiae S. Y. Kondr., L. Lokos et J.-S. Hur), Candelinella deppeanae (for Candelariella deppeanae M. Westb.), Opeltiella fraudans (for Candelaria fraudans Poelt et Oberw.), Opeltiella fibrosoides (for Candelaria fibrosoides M. Westb. et Froden), Opeltiella rubrisoli (for Candelariella rubrisoli D. Liu et J.-S. Hur), Opeltiella canadensis (for Candelariella canadensis H. Magn.), Protocandelariella subdeflexa (for Lecanora subdeflexa Nyl.), Protocandelariella blastidiata (for Candelariella blastidiata L. Yakovchenko) are provided.
Molecular data provided for Candelinella makarevichiae (including holotype and iso- type), as well as additional specimens of Candelaria asiatica from South Korea for the first time. The latter species (Candelaria asiatica) from China, as well as’Candelaria’ murrayi from Argentina, South America are recorded for the first time. Voucher of Candelariella vitellina from Antarctica is also identified based on molecular phylogeny. It is for the first time shown that ’Candelaria’murrayi is positioned in the outermost position to Candelaria s. str. branch of the phylogenetic tree of the Candelariaceae, and may belong to another genus. Status of the ’Candelariella’medians group, the’Candelariella’ placodizans group, as well as single species ’Candelariella’reflexa and’Candelaria’ pacifica, forming separate branches outside the Candelariella s. str. and Candelaria s. str. clades, will be clarified when additional molecular data will be accumulated. Candelariella subsquamulosa D. Liu et Hur, recently described from South Korea (Liu et al. 2019), proved to be a new synonym of Candelinella makarevichiae.
