“…To date, over 1000 non-lichenized fungal species [7] and 500 lichenized fungal species [8] have been recorded by collection or isolation from Antarctica. In recent years, many studies have used the next-generation sequencing (NGS) technique to reveal fungal diversity in various habitats of Antarctica, such as soil [6,[9][10][11][12][13][14], sediment [15], vegetation [14,16], air [17], and freshwater [14,18].…”

Background In the ice-free area of maritime Antarctica, fungi are the essential functioning group in terrestrial and marine ecosystems. Until now, no study has been conducted to comprehensively assess fungal communities in various habitats in Antarctica. We aimed to characterize fungal communities in the eleven habitats (i.e., soil, seawater, vascular plant, dung, moss, marine alga, lichen, green alga, freshwater, feather) in the Fildes Region (maritime Antarctica) using next-generation sequencing. Results A total of 12 known phyla, 37 known classes, 85 known orders, 164 known families, 313 known genera, and 320 known species were detected. Habitat specificity rather than habitat overlap determined the composition of fungal communities, suggesting that, although fungal communities were connected by dispersal at the local scale, the environmental filter is a key factor driving fungal assemblages in the ice-free Antarctica. Furthermore, 20 fungal guilds and 6 growth forms were detected. Many significant differences in the functional guild (e.g., lichenized, algal parasite, litter saprotroph) and growth form (e.g., yeast, filamentous mycelium, thallus photosynthetic) existed among different habitat types. Conclusion The present study reveals the high diversity of fungal communities in the eleven ice-free Antarctic habitats and elucidates the ecological traits of fungal communities in this unique ice-free area of maritime Antarctica. The findings will help advance our understanding of fungal diversity and their ecological roles with respect to habitats on a neighbourhood scale in the ice-free area of maritime Antarctica.

“…Sterile crustose lichens containing a trentepohlioid photobiont have, in recent decades, often been tentatively described in genera of Arthoniomycetes such as Opegrapha and Schismatomma (e.g. James 1971; Coppins & James 1989; Coppins et al 1992; Øvstedal & Schaefer 2013; Diederich et al 2017). However, determining the systematic position of sterile lichens is difficult using only morphological and chemical data, rendering these generic placements highly uncertain.…”

Opegrapha multipuncta and Schismatomma quercicola are two sterile European lichens reproducing only vegetatively by means of soredia. RAxML and Bayesian analyses of newly generated sequence data from the mitochondrial ribosomal RNA small subunit provide clear evidence that these two species do not belong to the Arthoniomycetes, but to the Lecanoromycetes. In our phylogenetic analyses, O. multipuncta is nested in the genus Porina (Porinaceae) as sister to P. austroatlantica, while S. quercicola is nested in the genus Schizotrema (Graphidaceae) as sister to S. zebrinum. The following new combinations are introduced: Porina multipuncta (Coppins & P. James) Ertz, Coppins & Frisch and Schizotrema quercicola (Coppins & P. James) Ertz, Frisch & Sanderson. Schizotrema quercicola represents the first record of the genus Schizotrema for Europe and the first sorediate member in this genus. The species is newly recorded from Norway. The lichenicolous habit of Arthonia invadens is confirmed.
