Abstract

New information about presence and features of some Lecanora species as well as their ecology and distribution in Antarctica are provided. Lecanora dispersa (Pers.) Sommerf. is confirmed to occur in the Antarctic region; L. sverdrupiana Řvst. is recorded for the first time from maritime Antarctica; L. torrida Vain. is reported as new for that Antarctic area and for the southern hemisphere. An attempt to summarize the present state of knowledge for the genus Lecanora in the Antarctic region is made. Several species, which require more in depth studies, are briefly discussed and an up-to-date list of species occurring in Antarctica is included.

Abstract

Lichens of relict penguin colonies and sites affected by active penguin colonies were investigated in Victoria Land, Ross Sea sector, continental Antarctica. A total of 17 coastal sites, seven in northern and ten in southern Victoria Land, have been investigated across 7 ° of latitude from 71 ° to 78 ° S. Altogether 40 taxa of lichens have been identified. Four of the recorded species are new to the Antarctic – Caloplaca erecta , C. soropelta , C. tominii and Physcia tenella ; two species are new to the Victoria Land area – Lecania nylanderiana and Lecanora polytropa . The first lichen records from Beaufort Island are also provided. Data presented here expand the knowledge on the occurrence, diversity and distribution of Victoria Land lichens.
