Abstract

Halici, M. G., Möller, E., Timdal, E., Kahraman Yiğit, M. & Bölükbaşi, E. 2022. Rhizocarpon ozsoyae sp. nova (Rhizocarpaceae, lichenized Ascomycetes) from James Ross Island (Antarctic Peninsula). – Herzogia 35: 105 –114.

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.

Die neue Flechtenart Rhizocarpon ozsoyae wird von James Ross Island in der nordöstlichen antarktischen Halbinselregion beschrieben. Die nrITS- und mtSSU-Genregionen der neuen Art wurden untersucht; die phylogenetische Position der Art liegt in der Rhizocarpon geographicum-Gruppe. Sie unterscheidet sich von den anderen Arten der Gruppe dadurch, dass sie meist 1-septierte und kleinere Ascosporen aufweist und von fast allen dadurch, dass sie Norstinsäure enthält.
