Rhizocarpon ozsoyae sp. nova (Rhizocarpaceae, lichenized Ascomycetes) from James Ross Island (Antarctic Peninsula)

Abstract

The new lichen species Rhizocarpon ozsoyae is described from James Ross Island, located in the north-eastern Antarctic Peninsula region. The nrITS and mtSSU gene regions of the new species are studied and the phylogenetic position of the species is in the Rhizocarpon geographicum group. It differs from the other species of the group by having mostly 1-septate and smaller ascospores, and from nearly all of them by containing norstictic acid.
