Catalogue of saxicolous lichens (Ascomycota) of the archaeological area of Siega Verde (Salamanca, Spain)
We here present the partial results of a research project focusing on the lichen diversity and lichen-induced biodeterioration processes in two archaeological places -Siega Verde, Spain, and Foz-Côa, Portugal, both declared World Heritage sites by the UNESCO-. In this article the floristic results corresponding to the area of Siega Verde -Salamanca- are presented. In total, 97 taxa of lichens and two lichenicolous fungi have been identified. The presence of Peltula lobata J.Marques & al., Cyphelium lecideinum (Nyl.) Trevis., Variospora cancarixiticola (Nav.-Ros. & al.) Arup & al., and the lichenicolous fungus Llimoniella phaeophysciae Diederich & al. is particularly relevant. Somedifferences have been observed between the floristic composition of this area and that of the neighbor of Foz-Côa, attributable to the eutrophicationof Siega Verde.
