A Revised taxonomy for the subfamily Xanthorioideae (Teloschistaceae, Ascomycota) based on molecular phylogeny

Research output: Contribution to journalArticle

Abstract

The phylogeny of the subfamily Xanthorioideae (Teloschistaceae) is re-analysed based on ITS, LSU and mtSSU sequences, including a new set of specimens representing 31 genera, of which five are proposed as new: Golubkovia, Igneoplaca, Langeottia, Scythioria and Verrucoplaca. Two new species, Ovealmbornia volkmarwirthii from South Africa and Gondwania sejongensis from Antarctica are described, illustrated and compared with closely related taxa. Eleven new combinations are proposed in the genera Calogaya, Cerothallia, Flavoplaca, Gondwania, Igneoplaca, Scythioria and Verrucoplaca, but the status of four earlier established genera, Pachypeltis, Parvoplaca, Solitaria and Xanthopeltis, remains uncertain and needs further studies.
