摘要：
Three new crustose lichen species are described from Sri Lanka. Chapsa pulchella Wijeyaratne, Locking & Lumbsch is unique due to its bright red apothecial margin contrasting with the white-pruinose disc. Pyrenula ocellulata Wijeyaratne, Lucking & Lumbsch resembles Pyrenula interducta and P. mastophoroides in having an inspersed hymenium and medium-sized ascospores, but differs in its shiny, hemispherical perithecia with sharply delimited thalline cover. Thelotrema minisporum Wijeyaratne, Lucking & Lumbsch is identical with Thelotrema lepadinum in morphology but its ascospores are much smaller and the thallus contains stictic acid.
