Abstract:

The known lichen diversity of Singapore, 296 species, is comparable with temperate lowland areas, but the taxa involved are different, even at high taxonomic levels: the commonest orders are Arthoniales and Graphidales instead of Lecanorales. Epiphytic species dominate, while saxicolous and terrestrial species are rare. Comparison with pre-2000 records and non-urbanized areas suggests a decrease in forest lichens, cyanophilous macrolichens, and the nitrophilous family Physciaceae.
