Abstract

The lichen flora of high ground in the west of Ireland is described by reference to four localities (Brandon Mountain, Muckanaght, Ben Bulben, Slieve League). These were selected on the basis of their reputation for calcicolous alpine vascular plants and for being some of the most highly oceanic mountains in Europe. The montane element in the lichen flora is strictly limited, populations being small and isolated, although sub-montane species are more frequent. A small group of 44 species has been identified, which is 30% fewer than is found in either the Lake District or Snowdonia; their distribution and ecology are described. The margin of high-level tarns on Brandon Mountain support communities of outstanding importance, including Rinodina fimbriata, new to the British Isles. Seventeen lichens are reported as being new to Ireland.
