“…However, the biodiversity of lichens in the Antarctic regions is still not fully known. New species are continuing to be described, which has become possible especially through the use of modern techniques such as DNA barcoding (Ruprecht et al 2020;Halıcı et al 2021Halıcı et al , 2022Lagostina et al 2021). These techniques also have the potential to reveal whether species for which only an endemic distribution was previously indicated are in fact bipolar, along continents (South to North America) or even globally distributed.…”

Two new species of the genus Lecidella, one with a North American-maritime Antarctic distribution and one with a so far exclusively southern South American-maritime Antarctic distribution, are described using molecular and morphological tools. Lecidella ayazii is a species growing on soil and also on mosses and has so far been found on the Antarctic Peninsula, as well as in the alpine areas of the La Sal Mountains, Utah, USA and in the Kivalliq Region (Nunavut) in the north of Canada, whereas L. drakensis occurs mainly on siliceous rocks, rarely on mosses, and has been recorded on both sides of the Drake Passage in southern Patagonia and the Antarctic Peninsula. Phylogenetic analysis of the nrITS sequence data shows that both species belong in the L. elaeochroma clade, each forming a highly supported and distinct group. Furthermore, they also differ in morphological and chemical characters from the species described so far in this clade. In addition, five further accessions were recorded from the maritime Antarctic, which were placed in the cosmopolitan and heterogeneous L. stigmatea clade, of which one could be assigned to the bipolar species L. siplei.

“…In a project aiming to determine the lichen biodiversity of this island with the aid of DNAbarcoding, the first author collected lichens from Horseshoe Island during Turkish Antarctic Expedition VI, 2022. From these collections, Candelariella ruzgarii Halıcı, A.M. Kahraman & Güllü (Halıcı, Kahraman Yiğit, Bölükbaşı, & Güllü, 2023a) and Lendemeriella vaczii Halıcı, Kahraman Yiğit & Güllü (Halıcı, Bölükbaşı, Güllü, Kahraman Yiğit, & Barták, 2023b) have already been described and published.…”

The new terricolous lichen species Thamnolecania yunusii Halıcı, Güllü, Bölükbaşı & Kahraman, which is characterised by its cream to greyish brown granulose-crustose thallus without vegetative propagules, is described from Horseshoe Island in the South-West Antarctic Peninsula region. All Thamnolecania species are known only from the Antarctic. The only species of the genus with a crustose thallus is T. racovitzae, but it differs from T. yunusii by growing on rocks, having an effuse to subeffigurate thallus that is sometimes isidiate and with shorter and narrower ascospores (c. 15 × 3.5 µm vs. 15.5–19.5 × 3.5–5.5 µm). The nrITS, mtSSU and RPB1 gene regions of the new species were studied and the phylogenetic position of the species was shown to be in the same clade as Thamnolecania gerlachei, T. brialmontii and T. racovitzae, but occurs on a different branch from these species. As T. yunusii is an Antarctic endemic, like the other Thamnolecania species, and most of the morphological characters fit well with this genus, we describe this new species under the genus Thamnolecania.

“…Our lichen biodiversity studies started in 2016 on James Ross Island, which belongs to the North-East Antarctic Peninsula region and has a special location in the transition zone between maritime and continental climate types (Bednarek-Ochyra et al 2000), and Horseshoe Island located in the south-west Antarctic Peninsula, clearly show that Antarctic lichen biodiversity is far from being fully known. Since 2016, our project team has described using molecular techniques four new lichenized fungal species from James Ross Island; namely Toniniopsis bartakii (Halıcı et al 2021a), Leptogium pirireisii (Halıcı et al 2022a) Rhizocarpon ozsoyae (Halıcı et al 2022b), Shackletonia backorii (Halıcı et al 2022c), and reported from this island 12 lichen species as new to Antarctica (Halıcı et al, 2017(Halıcı et al, , 2018(Halıcı et al, , 2020(Halıcı et al, , 2021b(Halıcı et al, , 2022dHalıcı and Barták 2019;Kahraman and Halıcı 2021).…”

Previously, only three Candelariella species were known from Antarctica: C. aurella, C. flava and C. vitellina. After morphologically and phylogenetically examining our collections on soil from James Ross Island, located in the north-east Antarctic Peninsula region, and Horseshoe Island, a small rocky island in Bourgeois Fjord, Marguerite Bay in the south-west Antarctic Peninsula, we describe the lichen species Candelariella ruzgarii as new to science. Sequences of the nrITS, mtSSU and RPB1 gene regions of the new species were amplified and revealed that the phylogenetic position of the new species is in the C. aurella group, which is characterised by 8-spored asci and ± granular thalli. Candelariella ruzgarii is phylogenetically most closely related to C. aurella s. lat. but differs mainly in ecology as the new species grows on soil or on terricolous lichens, whereas the latter species grows on calcareous rocks, rarely on wood. Morphologically, C. ruzgarii is very similar to C. aggregata, a Northern Hemisphere species that grows on mosses and plant debris. Apart from the different phylogenetical position, C. ruzgarii has a thicker and sometimes slightly crenulated thalline margin and somewhat shorter ascospores than C. aggregata. We also report C. plumbea for the first time from Antarctica, a species with a thick and grey thallus that was previously known from Europe and Asia.
