Abstract

To this day, merely 8% of all estimated fungi species are documented and, in certain regions, its biodiversity is practically unknown. Inside the Fungi Kingdom, macrofungi andlichens assume a critical part in the ecosystem functionality and have a historicalconnection to mankind's social, clinical and nutritious uses. Despite their importance, thediversity of these groups has been widely overlooked in the sub-Antarctic Region of Chile,a crucial area in the study of climate change due to its extraordinary biodiversity and itsproximity to Antarctica. Few studies regarding both groups have been conducted in thissub-Antarctic Region and the data are still scarce and inaccessible, as these are onlypublished in specialised journals, unreachable to local communities New informationThis publication presents a records compilation available in previous published scientificand technical reports on macrofungi and lichen diversity. In total, 1263 occurrence recordsof 618 species (341 records of 251 macrofungi species and 922 records of 367 lichenspecies) were digitised and integrated into the regional platform Biodiversity InformationSystem for Aysén (SIB-Aysén) and into GBIF. Here, we provide the fullest dataset on oneof the most diverse group of living beings in one of the the least-known world regions
