Abstract

Inventory of epiphytic macrolichens on trees used in urban arborization in Curitiba, Paraná, Brazil.

Abstract

The floristic composition of epiphytic macrolichens on the following tree species used in urban arborization in Curitiba was analysed: Acer negundo, Lagerstroemia indica, Ligustrum lucidum, Parapiptadenia rigida, Cassia leptophylla, Syagrus romanzoffiana, Tabebuia alba, Tabebuia chrysotricha, Tabebuia heptaphylla, and Tipuana tipu. A total of 84 species are reported, from which 14 are recorded for the first time in Paraná State and Flavoparmelia soredians is recorded for the first time in Brazil. Parmeliaceae was the best represented family, with 45 species distributed in nine genera, followed by Physciaceae with 24 species in six genera. The native tree species showed greater lichen species richness and a higher number of exclusive lichen species than the exotic tree species. The highest lichen species richness was found in Tabebuia chrysotricha with 62 taxa, followed by Syagrus romanzoffiana with 47. Candelaria concolor, Canoparmelia crozalsiana, Canoparmelia texana, Dirinaria applanata, Dirinaria confluens, Heterodermia obscurata, Myelochroa lindmanii, Parmotrema pilosum, Physcia poncinsii, Punctelia borreri, Punctelia reddenda, Pyxine subcinerea, Ramalina celastri and Ramalina peruviana are suggested as macrolichen species with the greatest potential for future biomonitoring studies of air quality in Curitiba.
