Abstract Some definitions of the term ‘lichen’ have often emphasized the role of the mycobiont as exhabitant in the symbiosis. Mastodia tessellata and Turgidosculum ulvae, both forming lichen-like associations with foliose algae, have traditionally defied that definition. In this study, we delve into the poorly known association of T. ulvae with Blidingia minima. Using four molecular markers (nrLSU, nrSSU, RPB1, mtSSU) we show that T. ulvae is a member of the family Verrucariaceae, closely… Expand

Symbiosis at its limits: ecophysiological consequences of lichenization to the genus Prasiola in Antarctica.
TLDR
The results support an improved tolerance to subzero temperature as main benefit of lichenization for the photobiont, but highlight thatLichenization represents a delicate equilibrium between a mutualistic and a less reciprocal relationship. Expand
Amphitropical variation of the algal partners of Pseudephebe (Parmeliaceae, lichenized fungi)
TLDR
The phylogeographic structure of green algae engaged in symbiosis with species in the genus Pseudephebe, including the Arctic and Antarctica, is explored to identify genetic lineages and their phylogenetic assignment and infer the haplotype distribution in relation with geography and the mycobiont’s identity. Expand
Differential responses to salt concentrations of lichen photobiont strains isolated from lichens occurring in different littoral zones
TLDR
The results highlight the role of photobionts in determining lichen zonation on rocky seashores and indicate differences in physiological behavior between supralittoral-dwelling and intertidal-Dwelling species. Expand

Lichen algae: the photosynthetic partners in lichen symbioses
Abstract A review of algal (including cyanobacterial) symbionts associated with lichen-forming fungi is presented. General aspects of their biology relevant to lichen symbioses are summarized. TheExpand

From Alaska to Antarctica: Species boundaries and genetic diversity of Prasiola (Trebouxiophyceae), a foliose chlorophyte associated with the bipolar lichen-forming fungus Mastodia tessellata.
TLDR
This study focuses on the photobiont partner of this lichen and was designed to explore and compare its genetic diversity along a latitudinal axis from Alaska to Antarctica, and proposes that at least two species of Prasiola associate with the lichen-forming fungus Mastodia tessellata. Expand
Revisiting photobiont diversity in the lichen family Verrucariaceae (Ascomycota)
TLDR
The diversity of photobionts in this lichen family was investigated using molecular markers amplified from DNA extracts of lichen thalli and cultured isolates to explore patterns of association between fungal and algal partners. Expand
Phylogenetic placement of some morphologically unusual members of Verrucariales
TLDR
The phylogenetic relationship of Flakea and Normandina with other lineages in Verrucariaceae remains elusive with the authors' multilocus dataset, and sequence data of protein-coding loci are required to increase phylogenetic resolution because morphological evolution seems to be dynamic inVerrucariales. Expand
The intertidal marine lichen formed by the pyrenomycete fungus Verrucaria tavaresiae (Ascomycotina) and the brown alga Petroderma maculiforme (Phaeophyceae): thallus organization and symbiont interaction.
TLDR
Despite the exceptional nature of the phycobiont involved, the Verrucaria tavaresiae-Petroderma maculiforme symbiosis unequivocally fits the prevailing concept of a lichen. Expand

The biological nature of some symbioses is unclear because it is often not easy to discern whether the symbionts obtain any benefits from the association. Mastodia tessellata, a symbiosis between aExpand
tufA phylogeny and species boundaries in the green algal order Prasiolales (Trebouxiophyceae, Chlorophyta)
TLDR
The results suggested that the species of Prasiola commonly involved in associations with fungi were probably P. delicata rather than P. crispa, as was formerly believed, and this gene may be a valuable phylogenetic marker at lower taxonomic levels in the Trebouxiophyceae and Ulvophycesae. Expand
Using a multigene phylogenetic analysis to assess generic delineation and character evolution in Verrucariaceae (Verrucariales, Ascomycota).
TLDR
The use of symplesiomorphic traits to define Verrucaria, the largest and type genus for the Verrucariaceae, as well as the non monophyly of the genera Polyblastia, Staurothele and Thelidium, explain most of the discrepancies between the current classification based on morphological similarity and a classification usingmonophyly as a grouping criterion.

Trouble with lichen: the re-evaluation and re-interpretation of thallus form and fruit body types in the molecular era.
TLDR
It is concluded that the lichen thallus is best interpreted as a novel phenotype with no exact homologue, and the critical position of lichens in developing an integrated approach to ascomycete evolution is emphasized. Expand
Phylogeny of the Gyalectales and Ostropales (Ascomycota, Fungi): among and within order relationships based on nuclear ribosomal RNA small and large subunits.
TLDR
Bayesian inference of phylogeny recovered the same topology as a conventional heuristic search using Maximum Likelihood as the optimization criterion and seems superior to bootstrapping in estimating support for short internal branches. Expand
Phylogenetic position of the brown algae-associated lichenized fungus Verrucaria tavaresiae (Verrucariaceae)
TLDR
Phylogenetic inferences from two nuclear and one mitochondrial loci confirm the placement of Verrucaria tavaresiae within the lichen family Verrucariaceae and more specifically within the marine genus Wahlenbergiella. Expand
