Species delimitation in the Cladonia gracilis group has long been known to be difficult due to morphological variability of taxa. The present study addresses the circumscription of species within this group, examining a number of specimens of the currently accepted taxa Cladonia coniocraea, C. cornuta subsp. cornuta, C. cornuta subsp. groenlandica, C. ecmocyna subsp. ecmocyna, C. ecmocyna subsp. intermedia, C. gracilis subsp. gracilis, C. gracilis subsp. elongata, C. gracilis subsp. tenerrima…

Coalescent-Based Species Delimitation Approach Uncovers High Cryptic Diversity in the Cosmopolitan Lichen-Forming Fungal Genus Protoparmelia (Lecanorales, Ascomycota)
TLDR
This study inferred the phylogeny of 18 species currently assigned to this genus based on 160 specimens and six markers and suggested the presence of a tropical and an extra-tropical lineage, and eleven previously unrecognized distinct species-level lineages in Protoparmelia s.l.
Phylogeny of the family Cladoniaceae (Lecanoromycetes, Ascomycota) based on sequences of multiple loci
TLDR
A new phylogeny of Cladoniaceae is constructed using five loci from a worldwide sample of 643 specimens representing 304 species and proposes the new genera Pulchrocladia and Rexia, as segregates of Cladia, five new combinations, and the resurrection of the genus Heterodea.
Multilocus phylogeny of the lichen-forming fungal genus Melanohalea (Parmeliaceae, Ascomycota): insights on diversity, distributions, and a comparison of species tree and concatenated topologies.
TLDR
Traditional phenotype-based species boundaries are assessed, previously unrecognized species-level lineages are identified and relationships among taxa within one major clade were largely unresolved in the species tree.
Using Phylogenetic and Coalescent Methods to Understand the Species Diversity in the Cladia aggregata Complex (Ascomycota, Lecanorales)
TLDR
It is proposed that results from these analyses support a 12 species delimitation scenario in the Cladia aggregata complex, suggesting that there is a high level of species diversity in the complex.
DNA barcode identification of lichen-forming fungal species in the Rhizoplaca melanophthalma species-complex (Lecanorales, Lecanoraceae), including five new species
TLDR
Five new species are formally described within the phenotypically circumscribed taxon Rhizoplaca melanophthalma sensu lato using support from the coalescent-based species delimitation method implemented in the program Bayesian Phylogenetics and Phylogeography (BPP) as the diagnostic feature distinguishing new species.
The phenotypic features used for distinguishing species within the Cladonia furcata complex are highly homoplasious
TLDR
The distribution in the phylogeny of the phenotypic characters traditionally used to distinguish the species in this complex of Cladonia furcata turned out to be polyphyletic, with the exception of the podetium type.
Coalescence-based species delimitation using genome-wide data reveals hidden diversity in a cosmopolitan group of lichens
TLDR
This study uses assignment-free multispecies coalescent-based species delimitation (STACEY, tr2-delimitation, and BP&P), phylogenetic methods, and clustering algorithms to investigate the inter- and infraspecific relationships within a common and widespread group of lichens with contentious species boundaries.
Species delimitation in Cladonia (Ascomycota): a challenge to the DNA barcoding philosophy
TLDR
The loci IGS rDNA, ef1α, rpb2 and cox1 were studied to find other markers that, in combination with the ITS rDNA region, can be used for species identification in Cladonia.
Testing the correlation between norstictic acid content and species evolution in the Cetraria aculeata group in Europe
TLDR
It is concluded that the production of norstictic acid in the C. aculeata group is most likely triggered by the environment (climate, edaphic factors, associated symbionts) and Cetraria steppae might be a different evolutionary lineage restricted to warm temperate regions but it is not uniquely characterized by the presence of nor STC.
Phylogenetic relationships among reindeer lichens of North America
TLDR
The monophyly of selected members of sections Crustaceae, Tenues, and Impexae and their relationships in the genus Cladonia were examined using the internal transcribed spacer region of the nuclear ribosomal DNA (ITS rDNA) and the mitochondrial small subunit gene of the mtSSU (mtSSU).

Convergent evolution in Cladonia gracilis and allies
TLDR
It is concluded that monophyly of the C. gracilis complex can be supported if C. maxima, C. coniocraea and C. ochrochlora are included in the complex, and species hypotheses that are reflected in the ITS2 RNA model are reflected.
Nomenclatural Notes on Cladonia Species
TLDR
The nomenclature and in part also the taxonomy of the following European lichens is discussed; the African lichen ‘ Cladonia gorgonina (Bory) Eschw.’ is typified and its nomenClatural status reconsidered.
The delimitation of Antarctic and bipolar species of neuropogonoid Usnea (Ascomycota, Lecanorales): a cohesion approach of species recognition for the Usnea perpusilla complex.
TLDR
A phylogenetic analysis revealed three related complexes of mainly asexual lineages arranged around three fertile Usnea species: U. perpusilla, which could also delimit an undescribed fertile species with yellow apothecia and a new asexual species from the High Andes.
THE SPECIES PAIR CONCEPT IN THE LICHEN DENDROGRAPHA LEUCOPHAEA (ARTHONIALES) : ANALYSES BASED ON ITS SEQUENCES
The internal transcribed spacers (ITS) of the nuclear ribosomal DNA were sequenced for 16 specimens of the lichen Dendrographa leucophaea (Tuck.) Darb. (Roccellaceae) in order to determine whether…
Exploring phenotypic plasticity and biogeography in emerald moths: A phylogeny of the genus Nemoria (Lepidoptera: Geometridae).
TLDR
A comparative analysis of the biogeographic history of Nemoria supports a South American origin for the genus with multiple introductions into North America, and an application of published substitution rates to the phylogram provides an age estimate of 7.5 million years.
LICHENS AND LICHENICOLOUS FUNGI OF THE QUEEN CHARLOTTE ISLANDS, BRITISH COLUMBIA, CANADA. 2. THE CLADONIACEAE
TLDR
Chemical variation in the Cladoniaceae is examined critically, and many taxa formerly recognized at the species or infraspecific levels are reduced to unnamed chemotypes.
Phylogeny of the Genus Cladonia s.lat. (Cladoniaceae, Ascomycetes) Inferred from Molecular, Morphological, and Chemical Data
TLDR
Phylogenetic relationships within the genus Cladonia, including Cladina, were reconstructed based upon simultaneous analyses of DNA sequences and morphological and chemical data, and a new provisional classification for the genus is proposed.
Testing "species pair" hypotheses: evolutionary processes in the lichen-forming species complex Porpidia flavocoerulescens and Porpidia melinodes.
TLDR
It is proposed that the observed results can be explained by conflicting reproductive and nutritional requirements imposed by an obligate symbiotic lifestyle and are the main forces that shape the evolution within the investigated species pair.
Sequence insertions and ITS data provide congruent information on Roccella canariensis and R. tuberculata (Arthoniales, Euascomycetes) phylogeny.
Four Roccella species, R. canariensis, R. fimbriata, R. montagnei, and R. tuberculata, were found to possess sequence insertions in up to four locations in the first half of the SSU rDNA. Insertions…
Genetic Diversity and Structure of Neotyphodium Species and Their Host Achnatherum sibiricum in a Natural Grass–Endophyte System
TLDR
It is proposed that endophyte infection of A. sibiricum might confer the host some selective advantages under certain conditions, which could help to maintain high-endophyte-infection frequencies in host populations, even when their gene flows do not match each other.
