Polar Research 27
ABSTRACT: The paper presents the results
of taxonomical work concerning the lichen genus Cladonia Hill ex
P. Browne from the Arctic island Spitsbergen (
). 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.
