Abstract


This paper contributes 96 species to the biota of lichenicolous fungi in the South Shetland Islands archipelago. New to science are the following genera: Antarctosphaeria Alstrup & Olech, gen. nov., Dahawkswia Alstrup & Olech, gen. nov., Lichenohostes Alstrup & Olech, gen. nov., Llanorella Alstrup & Olech, gen. nov., Phaeosporodendron Alstrup & Olech, gen. nov., and Prostratomyces Alstrup & Olech, gen. nov. Additionally, 31 species are described as new to science. These are: Antarctosphaeria bireagens Alstrup & Olech, sp. nov., A. lichenicola Alstrup & Olech, sp. nov., Arthonia dufayelensis Alstrup & Olech, sp. nov., A. livingstonensis Alstrup & Olech, sp. nov., A. massalongiae Alstrup & Olech, sp. nov., A. pertusariicola Alstrup & Olech, sp. nov., A. rakusae Alstrup & Olech, sp. nov., Carbonea austroshetlandica Alstrup & Olech, sp. nov., Cercidospora pertusariicola Alstrup & Olech, sp. nov., Dactylospora antarctica Alstrup & Olech, sp. nov., D. haematommatis Alstrup & Olech, sp. nov., Dahawkswia lichenicola Alstrup & Olech, sp. nov., Dendrophoma acarosporae Alstrup & Olech, sp. nov., Didymellopsis antarctica Alstrup & Olech, sp. nov., Lichenohostes citrinospora Alstrup & Olech, sp. nov., Lichenostigma corymbosae Alstrup & Olech, sp. nov., Llanorella ramalinae Alstrup & Olech, sp. nov., Metasphaeria verrucosa Alstrup & Olech, sp. nov., Micarea lichenicola Alstrup & Olech, sp. nov., Phaeospora antarctica Alstrup & Olech, sp. nov., P. convolutae Alstrup & Olech, sp. nov., Phaeosporodendron badiae Alstrup & Olech, sp. nov., Phoma acarosporae Alstrup & Olech, sp. nov., Prostratomyces leprariae Alstrup & Olech, sp. nov., P. ochrolechiae Alstrup & Olech, sp. nov., P. rhizocarpicolae Alstrup & Olech, sp. nov., Rhagadostoma antarctica Alstrup & Olech, sp. nov., Sphaerellothecium placopsiicola Alstrup & Olech, sp. nov., Stigmidium placopsiicola Alstrup & Olech, sp. nov., Taeniolella frigidae Alstrup & Olech, sp. nov., and Tetramelas caloplacae 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.
