The new species Xenolecia cataractarum Fryday is described from Campbell Island. It differs from X. spadicomma, the only other species of the genus, in having much smaller apothecia and ascospores, an olivaceously pigmented epihymenium (brown in X. spadicomma), and a thallus with a non-amyloid medulla and norstictic acid (amyloid medulla and confluentic acid in X. spadicomma). Xenolecia spadicomma is reported here from several localities on the Falkland Islands and three from the Región de Los Lagos, Chile, which are the first reports of this species since its description from Isla Wellington in the south-west of Patagonia in 1868. A full description of X. spadicomma is also provided.
