“…Some species were exclusively recorded in ultramafic or non-ultramafic areas, as previously reported in comparative analysis of serpentine and adjacent mafic outcrops (e.g. Sirois et al 1987;Paukov and Trapeznikova 2005;Favero-Longo and Piervittori 2009;Paukov 2009;Rajakaruna et al 2012) and similarity (S) in SDR analysis was slightly higher within ultramafic than in non-ultramafic areas, suggesting the possibility of some substrate-related species distributions. However, the species replacement (R) was the same for ultramafic and non-ultramafic areas, and the lower similarity in nonultramafic areas seems mostly related to differences in diversity richness rather than to peculiar species occurrences.…”

While higher plant communities found on ultramafics are known to display peculiar characteristics, the distinguishability of any peculiarity in lichen communities is still a matter of contention. Other biotic or abiotic factors, rather than substrate chemistry, may contribute to differences in species composition reported for lichens on adjacent ultramafic and non‐ultramafic areas. This work examines the lichen biota of ultramafics, at global and regional scales, with reference to species‐specific functional traits. An updated world list of lichens on ultramafic substrates was analyzed to verify potential relationships between diversity and functional traits of lichens in different Köppen–Geiger climate zones. Moreover, a survey of diversity and functional traits in saxicolous communities on ultramafic and non‐ultramafic substrates was conducted in Valle d'Aosta (North‐West Italy) to verify whether a relationship can be detected between substrate and functional traits that cannot be explained by other environmental factors related to altitude. Analyses (unweighted pair group mean average clustering, canonical correspondence analysis, similarity‐difference‐replacement simplex approach) of global lichen diversity on ultramafic substrates (2314 reports of 881 taxa from 43 areas) displayed a zonal species distribution in different climate zones rather than an azonal distribution driven by the shared substrate. Accordingly, variations in the frequency of functional attributes reflected reported adaptations to the climate conditions of the different geographic areas. At the regional scale, higher similarity and lower species replacement were detected at each altitude, independent from the substrate, suggesting that altitude‐related climate factors prevail over putative substrate–factors in driving community assemblages. In conclusion, data do not reveal peculiarities in lichen diversity or the frequency of functional traits in ultramafic areas.

“…With the addition of these species, the biodiversity of saxicolous lichens (including epigeic species permanently occurring in saxicolous environments, such as Cladoniaceae and Peltigeraceae) in the Middle and Southern Urals currently comprises above 550 species. This is twice higher than reported from the Middle Urals in our previous papers (Paukov & Trapeznikova, 2005;Paukov, 2009), but so far quite moderate compared to well-studied mountainous regions in Eurasia. The discovery of species with ranges extending to the Urals and distant from their previously known distributions will help to improve our knowledge of the lichen diversity of the region.…”

Ten species of lichenized ascomycetes are reported from the Urals. Aspicilia spermatomanes, Fuscidea praeruptorum, Lepra excludens, L. monogona, Metamelanea caesiella and Pertusaria amarescens are new to Russia while Bryobilimbia ahlesii, Lecanora orosthea, L. rouxii and Tephromela grumosa are new for the Urals. Our records considerably extend the ranges or fill gaps in the formerly disjunctive distributions of these species. The morphology, secondary chemistry and ecology of the species are discussed.

“…The Alps, together with the Mediterranean and sub-Mediterranean regions, have 10 species of Lobothallia (Roux 2012;Roux et al 2016;Nimis et al 2018), while territories situated north of latitude 50°N maintain a much lower diversity of Lobothallia. Only five species are known both from Fennoscandia and the Ural Mountains, with none endemic to these regions (Paukov & Trapeznikova 2005;Paukov 2009;Nordin et al 2011a).…”

Three species, Lobothallia brachyloba Paukov & I. V. Frolov, L. epiadelpha Paukov & A. Nordin and L. zogtii Paukov & Davydov, from arid regions of Eurasia (Russia, Kazakhstan, Kyrgyzstan, China and Mongolia) are described as new to science. Lobothallia brachyloba has flat, firmly attached lobes, immersed apothecia lacking a distinct thalline margin, and contains norstictic acid. Both Lobothallia epiadelpha and L. zogtii contain stictic acid and have a brown thallus and sessile apothecia. Lobothallia epiadelpha initially develops on crustose Circinaria spp, has thick lobes loosely attached to the substratum, and brown apothecial discs with constant thalline margins. Lobothallia zogtii is a free-living species with brownish black to jet black apothecial discs surrounded by a receding thalline margin. Lecanora bogdoënsis is synonymized with Lobothallia praeradiosa and Lobothallia helanensis is synonymized with L. subdiffracta. Three new combinations, Lobothallia hedinii (H. Magn.) Paukov, A. Nordin & Sohrabi, L. lacteola (Oxner) Şenkardeşler, Paukov, Davydov & Sohrabi, and L. subdiffracta (H. Magn.) Paukov, are proposed. Phylogenetic analyses of Lobothallia brachyloba, L. epiadelpha and L. subdiffracta (ITS, mtSSU) are presented, showing their relationships within Lobothallia. The lectotype of the name Aspicilia lacteola Oxner is designated. A key to 18 species of Lobothallia is provided.
