The total area is 2.175.600 km2 of which 341.700 km2 is free from permanent ice. The distance from south to north is 2670 km and from east to west 1050 km. The inland-ice covers 84% of the total area, and it is more than three km thick in the central part. The biggest ice-free areas are in the north- and northeast parts of the country, with other big areas in central west Greenland, and a substantial part also in the south, the target area of the present paper. The precipitation is highest in the south with more than 3000 mm/year, and only about 30 mm in the driest parts in the north. Mean temperatures in July vary between above 10ºC in the warm- 2 Folia Cryptog. Estonica est parts of the south and 2Cº in the coldest parts of the north. There are seven species of land-mammals in Greenland, but no reptiles or amphibians. The total population of Greenland is c. 50.000 persons of which c. 40.000 are Inuits, a mixture of Eskimos and Europeans. The economy is mainly based on ishing industry, with pastoralism (sheep, reindeer) being found in the southwestern part, and hunting in the northern areas. Agriculture is restricted to the inland area and is almost exclusively restricted to production of grass for winter fodder for the sheep. The geology of the study area is very complex with a variety of gneisses, granites, syenites, basalt, sandstones, limestones, and the special rocks of the Gardar-intrusion which contain high concentrations of a number of heavy metals and rare earth elements. The inland is dominated by high mountains dissected by valleys, while the coastal area is relatively lat and dissected by iords. The climatic variation is also considerable with the protected inland localities having temperatures reaching above 10ºC in July, which is enough for tree growth. The most important trees are Betula pubescens Erhr., B. glandulosa Michx., Salix glauca L. coll., and Juniperus communis L. ssp. nana Syme. Sorbus groenlandica (Schneid.) Löve & Löve, and Alnus crispa (Ait.) Pursh are found in some places. The moister and cooler coastal areas are free of tree growth but covered with different types of heathland, low scrubs, and moors (Böcher, 1975). The study area is approximately 3000 km², but almost half of it is sea, and other areas are inaccessible by foot. Roads are virtually absent outside settlements, and collections can only be made on daytrips by feet and boat, which means that many areas have never been visited by lichenologists. Therefore there is reason to believe, that many more species could be found in the area. Branth (1887) published the irst (and so far the only) lichen lora of the entire Greenland, with much information on South Greenland. The macrolichen lora of the area is quite well known especially due to studies by Eilif Dahl (Dahl, 1950). Dahl also collected microlichens but they have been worked up to a limited degree only, and have not been published before. Also Kjeld Hansen (K. Hansen, 1971) collected macrolichens in the area. Eric Steen Hansen (E. S. Hansen, 1978) made a comparative study of lichens on costal and inland localities of the area and also made several loristic papers in different parts of Greenland. Together with Pipaluk Lund he studied a grazing area for reindeer (E. S. Hansen & Lund 2003). Vagn Alstrup collected lichens in the Ilímaussaq-intrusion in the central part of the area in 1978 and 1980 and published some loristic contributions. Svanhildur Svane collected in the area in 1982, and some of her collections are reported by E. S. Hansen (2006a, 2006b). In 2005 the Nordic Lichen Society (NLS) held an excursion in the interior area around Narsarsuaq, with a postexcursion to a more coastal area. The area is probably the richest in lichens in Greenland due to the big climatic and geological variation, and because only here a rather well-developed epiphytic lichen lora is present. The panarctic lichen checklist (Kristinssson et al., 2006) divides Greenland into three regions. The present area is in the southern part of West Greenland, WG. Species reported new to the area (*) may be found in other areas of WG. MATERIALS AND METHODS The following list is based on the earlier publications and on observations and collections made mainly in connection with the NLS meeting in 2005. Furthermore, the list is supplemented with parts of Eilif Dahl´s collections, which have been identiied by the irst author. The not identiied yet part of Dahl´s collections is supposed to include common species in the genera Acarospora, Aspicilia, Buellia, Lecidea, Lecidella, Porpidia and Rhizocarpon. In addition, some interesting but unpublished inds from the material which had been collected by Vagn Alstrup in 1978 and 1980 (especially saxicolous taxa of the Ilímaussaq-intrusion in the central part of the study area) are also included here. In the species list references to earlier reports are only cited for rarer species; for that reason the following papers containing information on lichens in the area are not otherwise cited: Ahti & Hyvönen, 1985; Czeczuga & Alstrup, 1987; E. S. Hansen, 1975, 1984; Kärnefelt, 1979, 1986. 3 The localities For location of collecting sites, see the map (Fig. 1). Geology according to Escher & Pulvertaft (1995).

RESULTS This list enumerates all lichenized and lichenicolous fungi known from the west coast of South Greenland between 60º10’N and 61º20’N. Before the NLS excursion around 570 lichen species, varieties and forms, and 59 species of lichenicolous fungi were known from the area. These numbers have now grown to 744 and 156, respectively. Only three macrolichens are reported new to Greenland, while 50 microlichens and 31 lichenicolous fungi are new. Some new species collected during the excursion have been published elsewhere (Alstrup, 2009; Kocourková, 2009; Kowalewska et al., 2008; Savic & Tibell, 2007; Zhurbenko, 2009). Some of the collections reported here have not been identiied to species level. Further, a number of supposed undescribed lichenicolous fungi and lichens are known from the area. The lichen lora is rich and in general not much disturbed except in built up areas. However, sheep grazing and cultivation of grass for winter-fodder has a negative effect on shrub vegetation and therefore some lichens conined to shrubs of Betula and Salix become endangered, e.g. Fuscopannaria ahlneri, Lobaria scrobiculata, Nephroma spp., Peltigera collina, to name a few. There are also lichens restricted to metal-rich rocks which may be mined in the future. 5 The list *# ABROTHALLUS BERTIANUS De Not. – 6 (WvB), on Melanelia stygia.
