|Abstract: ||Abstract:Mycological information in the Arctic area is fragmentary and in the cataloguing phase. The first account of fungi from Svalbard has been published by Sommerfelt, while only the Basidiomycota groups were systematically studied. Recently, Aspergillus spp., Penicillium spp. and yeast species have been isolated from Arctic seawater, sea ice, snow in the tidal range and glacial ice. Diversity of soil and lignicolous marine fungi are well-documented in the tropical, subtropical and temperate areas, while that in the arctic region has not been researched. During two short visits to Troms?e, Longyearbyen (Svalbard) and Ny-?lesund (Svalbard) in Norway, 23 soil samples and 51 pieces of washed-up wood were collected to give a preliminary account of the diversity of soil and lignicolous marine fungi within the Arctic circle. For the lignicolous fungi, colonisation frequency was low as only 21 pieces of wood were colonised by marine fungi. Ascomycetes predominated on the wood and typical marine fungi of the temperate region, including Ceriosporopsis tubulifera and Lautosporopsis circumvestita, were collected at Troms?e. Two mitosporic fungi, Phoma sp. and Zalerion varium cf were also recorded from Troms?e. A different assemblage of marine fungi was recorded at Longyearbyen, where at least two new taxa were discovered. For the soil fungi, approximately 87 fungal taxa were recorded. Physiological studies on these fungi are essential to find out if these fungi are active in these environments and thus their roles in these hostile environments.|
