New records of lichenicolous fungi and lichenicolous lichens from the Iberian Peninsula, with the description of four new species and one new genus

(ENG) 110 records of lichenicolous fungi are reported from Andorra, Portugal and Spain, (mostly the latter country). One genus and four species are described as new to science: Phaeospora everniae on Evernia prunastri, Polycoccum ibericum on Rinodina sp., Zwackhiomacromyces constrictocarpus gen. et. sp. nov. on Megalospora, and Zwackhiomyces melanohaleae on Melanohalea exasperata. Pronectria septemseptata, is combined into the genus Xenonectriella as X. septemseptata (Etayo) Etayo & van den Boom. Lichenostigma canariense and Sarcopyrenia bacillosa are newly reported for Europe. Further new records for mainland Spain are Neolamya peltigerae, Niesslia cladoniicola, Obryzum corniculatum, Phacopsis fusca, Phoma grumantiana, Polycoccum umbilicariae, Sclerococcum leuckertii, Sphaerellothecium atryneae, Stigmidium cerinae, S. ramalinae and Taeniolella beschiana. A second world record of Pronectria casaresii is reported from northern Spain. The known distributions of many species are extended and discussed.
