Abstract

Mature as well as juvenile stages of thalli and apothecia occurring on numerous meteorite fragments found on Ella Island can be referred to 10 genera of lichens: Acarospora, Candelariella, Gyalidea, Lecanora, Lecidea, Physcia, Pseudephebe, Polysporina, Rinodina and Xanlhoria. In their colonization phase these lichens are influenced by the mineralogy and chemistry of the meteorite fragments. Thus Xanlhoria shows a distinct preference for the meteorite minerals rich in iron, whereas Candelariella appears to avoid these minerals.
