Information on the diversity and ecology of arctic marine fungi is lacking. During a short visit to Longyearbyen (78°13'N 15°33'E), Svalbard, Norway, a new marine fungus growing on driftwood collected at the shore was encountered. This taxon belongs to the Halosphaeriales (Ascomycota), a fungal order of mostly marine species. Havispora longyearbyenensis gen. et sp. nov. is morphologically similar to Nautosphaeria and Nereiospora, all with tufts of appendages at polar and equatorial positions of the ascospore but differing in color and septation of the ascospore and morphology and ontogeny of the ascospore appendage.

Key words: Ascomycota, driftwood, Halosphaeriaceae, taxonomy
