“…2), but perhaps not unexpected considering earlier studies that had highlighted a phylogenetic structure indicative of several species complexes (e.g., Goffinet & al., 2003;. Furthermore, the dramatic increase in species richness in this section parallels the trend emerging from inferences based on DNA data in other lineages of Peltigerales Lücking & al., 2017;Magain & al., 2017a, b;Simon & al., 2018), as well as in other groups of lichen-forming fungi.…”

This comprehensive phylogenetic revision of sections Peltigera and Retifoveatae of the cyanolichen genus Peltigera is based on DNA sequences from more than 500 specimens from five continents. We amplified five loci (nrITS, β-tubulin and three intergenic spacers part of colinear orthologous regions [COR]) for the mycobiont, and the rbcLX locus for the cyanobacterial partner Nostoc. Phylogenetic inferences (RAxML, BEAST) and species delimitation methods (bGMYC, bPTP, bPP) suggest the presence of 88 species in section Peltigera, including 50 species new to science, hence uncovering a surprisingly high proportion of previously unnoticed biodiversity. The hypervariable region in ITS1 (ITS1-HR) is a powerful marker to identify species within sections Peltigera and Retifoveatae. Most newly delimited species are restricted to a single biogeographic region, however, up to ten species have a nearly cosmopolitan distribution. The specificity of mycobionts in their association with Nostoc cyanobionts ranges from strict specialists (associate with only one Nostoc phylogroup) to broad generalists (up to eight Nostoc phylogroups uncovered), with widespread species recruiting a broader selection of Nostoc phylogroups than species with limited distributions. In contrast, species from the P. didactyla clade characterized by small thalli and asexual vegetative propagules (soredia) associate with fewer Nostoc phylogroups (i.e., are more specialized) despite their broad distributions, and show significantly higher rates of nucleotide substitutions.

“…Many cyanolichen groups related to Rostania have recently been the subject of major studies, where substantial amounts of overlooked biodiversity has been recovered. Examples include large foliose lichen groups such as Pseudocyphellaria [32,33] Sticta [34] and Peltigera [35] but also more closely related groups in the Collemataceae like Leptogium [36]. Considering the substantial morphological variation and the indications from our earlier phylogenetic studies, Rostania is likely to contain several yet unrecognised species, even in a well-documented area like Europe.…”

Species delimitation in the cyanolichen genus Rostania

Background In this study, we investigate species limits in the cyanobacterial lichen genus Rostania (Collemataceae, Peltigerales, Lecanoromycetes). Four molecular markers (mtSSU rDNA, β-tubulin, MCM7, RPB2) were sequenced and analysed with two coalescent-based species delimitation methods: the Generalized Mixed Yule Coalescent model (GMYC) and a Bayesian species delimitation method (BPP) using a multispecies coalescence model (MSC), the latter with or without an a priori defined guide tree. Results Species delimitation analyses indicate the presence of eight strongly supported candidate species. Conclusive correlation between morphological/ecological characters and genetic delimitation could be found for six of these. Of the two additional candidate species, one is represented by a single sterile specimen and the other currently lacks morphological or ecological supporting evidence. Conclusions We conclude that Rostania includes a minimum of six species: R. ceranisca, R. multipunctata, R. occultata 1, R. occultata 2, R. occultata 3, and R. occultata 4,5,6. Three distinct Nostoc morphotypes occur in Rostania, and there is substantial correlation between these morphotypes and Rostania thallus morphology.

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.
