2008
Osyczka, Piotr | Węgrzyn, Michał
Eighteen species of eleven lichen genera were found on driftwood and worked timber deposited on the beaches in the Hornsund and Billefjorden regions (the west coast of Spitsbergen, Svalbard archipelago). Majority of them indicate low substrate specificity in the high arctic regions. Only three species (Caloplaca spitsbergensis, Lecanora mughicola, L. orae-frigidae) are typical for lignum. Most of the taxa are widespread in Svalbard. Species like: Caloplaca holocarpa, C. spitsbergensis, Protothelenella sphinctrinoidella, Rinodina archaea were sporadically reported till now. Lecanora mughicola was not reported from Svalbard up to the present and this is the first record of the species for the region.
