The lichenicolous fungi of the South Shetland Islands, Antarctica: species diversity and identification guide
This paper contributes 96 species to the biota of lichenicolous fungi in the South Shetland Islands archipelago. New to science are the following genera: <em>Antarctosphaeria</em> Alstrup & Olech, gen. nov., <em>Dahawkswia</em> Alstrup & Olech, gen. nov., <em>Lichenohostes</em> Alstrup & Olech, gen. nov., <em>Llanorella</em> Alstrup & Olech, gen. nov., <em>Phaeosporodendron</em> Alstrup & Olech, gen. nov., and <em>Prostratomyces</em> Alstrup & Olech, gen. nov. Additionally, 31 species are described as new to science. These are: <em>Antarctosphaeria bireagens</em> Alstrup & Olech, sp. nov., <em>A. lichenicola</em> Alstrup & Olech, sp. nov., <em>Arthonia dufayelensis</em> Alstrup & Olech, sp. nov., <em>A. livingstonensis</em> Alstrup & Olech, sp. nov., <em>A. massalongiae</em> Alstrup & Olech, sp. nov., <em>A. pertusariicola</em> Alstrup & Olech, sp. nov., <em>A. rakusae</em> Alstrup & Olech, sp. nov., <em>Carbonea austroshetlandica</em> Alstrup & Olech, sp. nov., <em>Cercidospora pertusariicola</em> Alstrup & Olech, sp. nov., <em>Dactylospora antarctica</em> Alstrup & Olech, sp. nov., <em>D. haematommatis</em> Alstrup & Olech, sp. nov., <em>Dahawkswia lichenicola</em> Alstrup & Olech, sp. nov., <em>Dendrophoma acarosporae</em> Alstrup & Olech, sp. nov., <em>Didymellopsis antarctica</em> Alstrup & Olech, sp. nov., <em>Lichenohostes citrinospora</em> Alstrup & Olech, sp. nov., <em>Lichenostigma corymbosae</em> Alstrup & Olech, sp. nov., <em>Llanorella ramalinae</em> Alstrup & Olech, sp. nov., <em>Metasphaeria verrucosa</em> Alstrup & Olech, sp. nov., <em>Micarea lichenicola</em> Alstrup & Olech, sp. nov., <em>Phaeospora antarctica</em> Alstrup & Olech, sp. nov., <em>P. convolutae</em> Alstrup & Olech, sp. nov., <em>Phaeosporodendron badiae</em> Alstrup & Olech, sp. nov., <em>Phoma acarosporae</em> Alstrup & Olech, sp. nov., <em>Prostratomyces leprariae</em> Alstrup & Olech, sp. nov., <em>P. ochrolechiae</em> Alstrup & Olech, sp. nov., <em>P. rhizocarpicolae</em> Alstrup & Olech, sp. nov., <em>Rhagadostoma antarctica</em> Alstrup & Olech, sp. nov., <em>Sphaerellothecium placopsiicola</em> Alstrup & Olech, sp. nov., <em>Stigmidium placopsiicola</em> Alstrup & Olech, sp. nov., <em>Taeniolella frigidae</em> Alstrup & Olech, sp. nov., and <em>Tetramelas caloplacae</em> Alstrup & Olech, sp. nov. Furthermore, a literature survey was undertaken, which resulted in the preparation of an identification guide for the lichenicolous species occurring in the South Shetlands Islands.
