More than half of the lichens recorded are cosmopolitan (35%) species or New Zealand endemics (20%), with the remainder showing the following affinities: australasian (17%), pantropical (13%), austral (7%), palaeotropical (5%) and Western Pacific (3%). A distinctive perlatolic acidcontaining strain of Neofuscelia pulla appears to be confined to the Three Kings Islands. Great Island is the type locality for Erioderma sorediatum. Endocarpon cf. adscendens, Phyllopsora cf. haemophaea and Pyxine cocoes are additions to the New Zealand lichen flora, and an undescribed species of Trapeliopsis occurs on Metrosideros excelsa bark.
