Kondratyuk, SY/ Kärnefelt, I 2003: Revision of three natural groups of xanthorioid lichens (Teloschistaceae, Ascomycota). - Ukrayins'kyi Botanichnyi Zhurnal60(4): 427-437. [RLL Suppl.] Keywords: OXNERIA/ RUSAVSKIA/ XANTHOANAPTYCHIA
Abstract: Status of three natural groups of xanthorioid lichens (Teloschistaceae), namely Xanthomendoza ulophyllodes, Xanthoria elegans and Teloschistes villosus groups is revised. Their status is elevated to the generic level. They are segregated from other hitherto accepted groups, namely Oxneria (with type species Oxneria alfredii (S. Kondr. & Poelt) S. Kondratyuk & Karnefelt) from Xanthomendoza, Rusavskia (with type species Rusavskia elegans (Link) S. Kondratyuk. & Karnefelt) from Xanthoria; and Xanthoanaptychia (with type species Xanthoanaptychia villosa (Ach.) S. Kondratyuk & Karnefelt) from. Teloschistes. Descriptions and comparison. with allied lichen groups are provided. Totally 39 new combinations (21 for the representatives of the genus Oxneria, 14 species of the genus Rusavskia, and 6 of the genus Xanthoanaptychia) mainly for all Holarctic representatives of xanthorioid groups mentioned are proposed. Synonyms for some taxa are for the first time provided.
