Four lichen species new to the Antarctic and sub-Antarctic South Georgia are reported. One is new to science: a species of Leciophysma with rough, non-granular thallus and reduced proper exciple. A total of 484 lichenized fungal taxa have now been reported from Antarctica and South Georgia.

New records of Antarctic lichens
Recent collections from King George Island, Deception Island and the Antarctic Peninsula provide evidence of the presence of previously unrecorded lichen taxa in the Antarctic flora. Parmelia
Freshwater diatom biogeography and the genus Luticola: an extreme case of endemism in Antarctica
TLDR
It is reported that Luticola has one of the highest endemic rates of any diatom genus in Antarctica, in terms of total number of species (taxon endemism) and percentage of the entire genus (phylogenetic end emism).
Psoroma antarcticum, a new lichen species from Antarctica and neighbouring areas
TLDR
The aim of the present study is to describe Psoroma antarcticum as new to science, study its habitat ecology and total distribution, and include a genetic analysis with respect to its internal variation and relationship to other species.
Lecanora muscigena (Lichenized Ascomycota, Lecanorales), a new lichen species in the Lecanora fuscescens group from South Georgia
TLDR
A new species is described from the subantarctic island of South Georgia from a collection made in 1980 that was previously included as Trapeliopsis sp.
The lichenicolous fungi of the South Shetland Islands, Antarctica: species diversity and identification guide
TLDR
This paper contributes 96 species to the biota of lichenicolous fungi in the South Shetland Islands archipelago, including 31 species described as new to science.
Yeasts from macroalgae and lichens that inhabit the South Shetland Islands, Antarctica.
TLDR
Results suggest that Antarctic phyco and lichensphere represent a huge substrate for cold-adapted yeasts and enhanced the knowledge of the microbiota from extreme environments.
A new lichen species from the Heritage Range, Ellsworth Mountains, Antarctica
Uma nova especie de liquen, com soralia e acido norstictico, Opegrapha edsonii e descrita, ocorrendo nas Montanhas Ellsworth, Antartica continental.
Biometrical analysis and thallus morphology characteristics of Placopsis antarctica from King George Island, Antarctica ( Short Communication )
Placopsis antarctica is an ornithocoprophilous lichen that has been for a long time confused with P. contortuplicata I. M. Lamb. In our study, we focused on morphological characteristics of P.
The lithic microbial ecosystems of Antarctica’s McMurdo Dry Valleys
Abstract We review the lithic microbial ecosystems of the McMurdo Dry Valleys as the main form of terrestrial colonization in this region, and assess the role of environmental controls such as
The joint action in the bioactivity studies of Antarctic lichen Umbilicaria antarctica: Synergic-biodirected isolation in a preliminary holistic ecological study
TLDR
A phytochemical study of Antarctic lichen collected from maritime Antarctica has been carried out and joint action studies on mixtures of the compounds carried out − a methodology that may be the way to a holistic approach in the ecological studies of lichens.

A new species of the genus Porpidia from Antarctica
TLDR
A new endemic species, Porpidia submelinodes Osyczka & Olech, recognized in the South Shetlands and South Orkneys, is described, primarily characterized by its rusty orange, sorediate thallus and the absence of lichen secondary products detectable by TLC.
Notes on the lichen genus Rhizoplaca from continental Antarctica and on some other species from northern Victoria Land
Abstract Five taxa of the genera Omphalodina and Rhizoplaca known from continental Antarctica are reassessed in order to identify a remarkable species collected from northern Victoria Land, for which
A new species of Placopsis (Agyriaceae: Ascomycota) from Antarctica
Placopsis antarctica, which is apparently endemic to antarctic regions south of lat. 60°S (South Orkney Is, South Shetland Is and the Antarctic Peninsula), is described. Details of its morphology,

TLDR
Environment and lichen ecology of Antarctica and South Georgia and ecological accounts of the genera and species are summarized and described.
Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters
TLDR
Maximum parsimony, maximum likelihood and Bayesian analyses agreed in placing the samples from continental Antarctica into four major groups, which are identified as the following species Lecidea cancriformis, L. andersonii as well as the new species L. polypycnidophora Ruprecht & Türk sp.
Phylogenetic and morphological analysis of Antarctic lichen-forming Usnea species in the group Neuropogon
TLDR
Phylogenetic analyses indicated that species circumscription in the Neuropogon group needs revision, with the principal species being non-monophyletic, and none of the morphological characters, or groups of characters, used in this study proved to be completely unambiguous markers for a single species.
The phylogeny and classification of Neuropogon and Usnea (Parmeliaceae, Ascomycota) revisited
TLDR
The phylogeny of usneoid lichens with black pigmentation in the cortex was reconstructed using Bayesian and maximum parsimony analyses of nuclear ITS rDNA sequences and indicates that Neuropogon is polyphyletic with a core group nested within Usnea subgen.
New species and combinations in Calvitimela and Tephromela from the southern subpolar region
TLDR
The new species Calvitimela austrochilenis Fryday and Tephromela superba Fryday are described: the former from several collections from southern Chile and one from Marion Island, and the latter from southern South America, Campbell Island, New Zealand, and Antarctica.
Slippery when wet: phylogeny and character evolution in the gelatinous cyanobacterial lichens (Peltigerales, Ascomycetes).
TLDR
Reconstructions of the number of character state transformations in exciple structure, thallus gelatinosity, and ascus apex structure indicate that thenumber of transformations is distinctly higher than the minimum possible.
