The present study is the first review of the foliose Parmeliaceae s. lat. lichens from andean and subandean Patagonia and Tierra del Fuego (southern South-America, 37°to 55° S). It covers habitats of Nothofagus forests includedin the Subantarctic Province (Antarctic Region) and theshrubby and gramin...

The present study is the first review of the foliose Parmeliaceae s. lat. lichens from andean and subandean Patagonia and Tierra del Fuego (southern South-America, 37°to 55° S). It covers habitats of Nothofagus forests includedin the Subantarctic Province (Antarctic Region) and theshrubby and graminean steppe of the Altoandinean and Patagonic Provinces (Neotropical Region). Six maps of the areaare included. The work is based on the study of ca. 500 specimenscollected by the author and herbarium collections from ASU, BAFC, BCRU, BM, BP, CHR, CTES, H, LIL, MB, MERL, SI, UPS. All collections have been studied in their morphology,anatomy and Chemistry, including TLC. The delimitation of Parmeliaceae s. lat. is discussedand a diagnosis is given. Forty seven species and two subspecies, included innineteen different genus are reported. Each genera ischaracterized and a key to identify the genera is presented,as well as a key to identify species within each genus. Morphological, anatomical and chemical features of eachspecies are given. When new features are decribed, they areillustrated. Taxonomic affinities, ecological behavior andintraspecific variability are discussed. The distribution ofeach taxa is given. The different habitats and species areillustrated by 92 photographs. Sixteen species are reported for the first time from Argentina, among which one for the first time for the Southern Hemisphere, three for southern-South America andthree for the first time outside Australasia. Severalsynonymies are discussed. Chemical data on Menegazzia species from southern South America are presented for the first time and somecollections are considered as possible new species. Biogeographically it was found that only three speciesare common to the centrally located Buenos Aires Province (Argentina), while two genera, twenty species belonging totwelve genera and three subspecies are shared with Australasia. This data are a further evidence of the resemblance ofthe cool temperate Nothofagus forests of circumantarcticterritories, formerly belonging to Gondwanaland. The work is considered a contribution to thebiodiversity of the area, due to the new taxa reported aswell as for the intraspecific variability described. It isalso considered as a good base to start researches on theuse of lichens as bioindicators, as done recently throughthe evaluation of elemental composition of some Parmeliaceaelichens.
