 abstract={The paper presents the results of taxonomical work concerning the lichen genus Cladonia Hill ex P. Browne from the Arctic island Spitsbergen (Svalbard). The work is based on studies of herbarium material collected during several Polish expeditions (deposited in Polish herbaria) and on the field work carried out by the author in 2002. The materials originate from the west coast of the island. Specimens were studied using methods of classical taxonomy supported by chemical analysis of the lichen substances. Twenty-seven taxa have been recognized in the materials examined. The description (morphological characters and chemistry), ecology and distribution of particular taxa are presented. An updated key for identification of taxa is included. Habitus photos of the species are submitted.},
