“…Indeed, although it is sensitive to the choice of priors, it can explore the entire space of species trees including evolutionary processes causing discordance, such as ILS (Incomplete Lineage Sorting). The STACEY approach has been successfully applied to species delimitation in several lichen groups (Boluda et al 2019;Gerlach et al 2019;Mark et al 2019;Lutsak et al 2020) and seems to avoid the overestimation of the number of potential species usually encountered with BPP (Edwards et al 2016).…”

We present phylogenetic analyses of the fruticose Ramalinaceae based on extensive collections from many parts of the world, with a special focus on the Vizcaíno deserts in north-western Mexico and the coastal desert in Namibia. We generate a four-locus DNA sequence dataset for accessions of Ramalina and two additional loci for Niebla and Vermilacinia. Four genera are strongly supported: the subcosmopolitan Ramalina, the new genus Namibialina endemic to SW Africa, and a duo formed by Niebla and Vermilacinia, endemic to the New World except the sorediate V. zebrina that disjunctly occurs in Namibia. The latter three genera are restricted to coastal desert and chaparral where vegetation depends on moisture from ocean fog. Ramalina is subcosmopolitan and much more diverse in its ecology. We show that Ramalina and its sister genus Namibialina diverged from each other at c. 48 Myrs, whereas Vermilacinia and Niebla split at c. 30 Myrs. The phylogeny of the fruticose genera remains unresolved to their ancestral crustose genera. Species delimitation within Namibialina and Ramalina is rather straightforward. The phylogeny and taxonomy of Vermilacinia are fully resolved, except for the two youngest clades of corticolous taxa, and support current taxonomy, including four new taxa described here. Secondary metabolite variation in Niebla generally coincides with major clades which are comprised of species complexes with still unresolved phylogenetic relationships. A micro-endemism pattern of allopatric species is strongly suspected for both genera, except for the corticolous taxa within Vermilacinia. Both Niebla and saxicolous Vermilacinia have chemotypes unique to species clades that are largely endemic to the Vizcaíno deserts. The following new taxa are described: Namibialinagen. nov. with N. melanothrix (comb. nov.) as type species, a single new species of Ramalina (R. krogiae) and four new species of Vermilacinia (V. breviloba, V. lacunosa, V. pustulata and V. reticulata). The new combination V. granulans is introduced. Two epithets are re-introduced for European Ramalina species: R. crispans (= R. peruviana auct. eur.) and R. rosacea (= R. bourgeana auct. p.p). A lectotype is designated for Vermilacinia procera. A key to saxicolous species of Vermilacinia is presented.

“…This fact may apply among others to the genus Rhizoplaca for which high chemical variability has been shown ( Wei & Wei, 2005 ; Zhou et al, 2006 ; Leavitt et al, 2013a ). On the other hand, in many cases chemistry may be successfully used as a character to support the circumscription of particular lichen taxa ( Elix, Corush & Lumbsch, 2009 ; Leavitt, Johnson & St. Clair, 2011 ; Molina et al, 2011 ; Spribille, Klug & Mayrhofer, 2011 ; Onut-Brännström, Johannesson & Tibell, 2018 ; Mark et al, 2019 ). This was demonstrated within the R. melanophthalma species complex in the case of R. parilis S.…”

Background Rhizoplaca subdiscrepans (Nyl.) R. Sant., a saxicolous, placodioid lichen, is considered to have a worldwide distribution in warm-temperate to boreal-arctic areas in Asia, Europe and North America. However, recent studies have revealed that this species includes five unrecognized species-level lineages—‘subd A, B, C, D and E’. During research focused on the diversity of saxicolous lichens in mountainous areas of southern Poland, some interesting representatives of the genus Rhizoplaca were found. The main aim of our study was to determine the taxonomic status of the collected specimens by means of molecular tools and a comparative analysis of similar herbarium materials. Methods Detailed morphological, anatomical and chemical examinations of reference material from Asia, Europe and North and South America focused primarily on a selected group of lecanoroid taxa with a placodioid thallus. In addition, 21 new generated sequences representing Lecanora pseudomellea, Protoparmeliopsis muralis, Rhizoplaca opiniconensis, R. subdiscrepans s. lat. and R. phaedrophthalma were selected for molecular study using the internal transcribed spacer region (ITS rDNA), together with 95 available GenBank sequences mainly from the genus Rhizoplaca. Results Polish specimens that clustered with members of a potential species-level lineage ‘subd E’ of Rhizoplaca subdiscrepans complex were recovered. Comprehensive analyses of the lichen group led us to the conclusion that lineage ‘subd E’ represents R. subdiscrepans s. str. and that the taxon appears to have a limited geographical distribution and specific habitat preferences. Furthermore, some of the recently defined species candidates within R. subdiscrepans s. lat.—‘subd D’ and ‘subd A’—should be assigned to two previously known species of Rhizoplaca, namely R. opiniconensis (Brodo) Leavitt, Zhao Xin & Lumbsch and R. phaedrophthalma (Poelt) Leavitt, Zhao Xin & Lumbsch, respectively. These two species are characterized by phenotypic features observed as well in analyzed specimens representing lineages ’subd D’ and ’subd A’. Moreover, the representatives of these lineages demonstrate some differences in occupied habitat and geographical range that also correspond with the indicated species. Additionally, it was found that Lecanora pseudomellea B.D. Ryan is a strongly supported monophyletic lineage within Rhizoplaca, and therefore an appropriate new combination for the species is proposed.

DNA barcodes are increasingly being used for species identification amongst the lichenised fungi. This paper presents a dataset aiming to provide an authoritative DNA barcode sequence library for a wide array of Nordic lichens. We present 1324 DNA barcode sequences (nrITS) for 507 species in 175 genera and 25 orders. Thirty-eight species are new to GenBank and, for 25 additional species, ITS sequences are here presented for the first time. The dataset covers 20–21% of the Nordic lichenised species. Barcode gap analyses are given and discussed for the three genera Cladonia, Ramalina and Umbilicaria. The new combination Bryobilimbia fissuriseda (Poelt) Timdal, Marthinsen & Rui is proposed for Mycobilimbia fissuriseda and Nordic material of the species, currently referred to as Pseudocyphellaria crocata and Psoroma tenue ssp. boreale, are shown to belong in Pseudocyphellaria citrina and Psoroma cinnamomeum, respectively.
