Genera of xanthorioid lichens (Teloschistaceae, Ascomycota) supported by molecular phylogeny (list, key to identification, position)

Key to genera of the xanthorioid lichens proposed during last 15 years (Kondratyuk & Kärnefelt 1997, 2003; Fedorenko et al.2009, 2012) and having support after molecular phylogeny (Fedorenko et al.2009, 2012; Кондратюк и др. 2013) and after data of morphological and anatomical revision, as well as a list of all 15 genera accepted (Gallowayella, Jackelixia, Jesmurraya, Josefpoeltia, Honeggeria, Martinjahnsia, Massjukiella, Oxneria, Ovealmbornia, Rusavskia, Seirophora, Xanthodactylon, Xanthokarrooa, Xanthomendoza andXanthoria) with references to original description and type species is provided. Position of xanthorioid lichens in two subfamilies (Caloplacoideae and Xanthorioideae) of the family Teloschistaceae is discussed.
