Phylogenetic hypotheses provide a context for examining the evolution of heterotrophic lifestyles. The lichen lifestyle, which is the symbiotic association of fungi with algae, is found in various representatives of Dicaryomycotina, both Ascomycetes and Basidiomycetes. A highly resolved parsimony analysis of small subunit ribosomal DNA (SSU rDNA) sequences suggests at least five independent origins of the lichen habit in disparate groups of Ascomycetes and Basidiomycetes. Because lichen… Expand
Lichen-Forming Fungi, Diversification of
TLDR
Molecular data helped to revise the species delimitation in fungi and showed that endemism occurs in these fungi and has arisen recently, there is a growing body of evidence that diversification events are correlated with climatic changes. Expand
A reclassification of Mycophycias ascophylli (Ascomycota) based on nuclear large ribosomal subunit DNA sequences
TLDR
Phylogenetic analysis indicates that Mycophycias ascophylli (phycobionts Ascophyllum nodosum, Pelvetia canaliculata) is misclassified in Verrucariales (Eurotiomycetes) and calls into question the current classification of the other species of Myc morphology, M. apophlaea. Expand
Group I introns in lichen forming fungi and their application for phylogenetic analysis
TLDR
There are multiple group I introns insertion sites in SSU rDNA of lichen forming fungi, and their secondary structures gives the evidences of transposition when group I intruder are in its nature states, demonstrating that group I intrusion are only suitable for the phylogenetic analysis at infraspecific levels.

Lichenized Fungi and the Evolution of Symbiotic Organization.
TLDR
Besides the morphologically recognizable diversity of the lichen mycobionts and lichenicolous (lichen-inhabiting) fungi, many other microorganisms including other fungi and bacterial communities are now detected in lichens by culture-dependent and culture-independent approaches. Expand
Early molecular investigations of lichen-forming symbionts: 1986-2001*.
  • P. DePriest
  • Biology, Medicine
  • Annual review of microbiology
  • 2004
TLDR
This review examines the influence of molecular investigation on lichenology during this first 15 years by examining the phylogenetic placement of the individual symbiotic partners with their free-living relatives, refining their nomenclature and classification. Expand
A Re-Examination of Generic Concepts of Baeomycetoid Lichens Based on Phylogenetic Analyses of Nuclear ssu and Lsu Ribosomal Dna
TLDR
Phylogenetic analyses of nucleotide sequence data support the resurrection of Dibaeis from its previous synonymy with Baeomyces based on the characters of ascocarp colour and ascus morphology, and the recognition of two distinct genera is consistent with character state distribution of unique lichen acids. Expand
Ecological and evolutionary role of photobiont-mediated guilds in lichens
TLDR
It is argued that the present diversity of lichen symbionts has evolved within an ecological kaleidoscope of photobiont-mediated guilds. Expand
Evolution of Ascomycota-Arthropoda Symbioses
TLDR
Whether it is for spore dispersal of the fungus or detoxification of recalcitrant and noxious plant compounds in arthropod diets, the evolutionary opportunities and symbionts’ abilities to establish fungal-arthropod symbioses are ever present and represent an on-going and dynamic process. Expand
Progress in understanding the evolution and classification of lichenized ascomycetes
TLDR
The current classification of ascomycetes is reviewed in the light of recent molecular data and a number of convergent phenotypic developments in lichenized ascomYcete are shown. Expand
Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi.
TLDR
The phylogenetic hypothesis supports the independent origin of lichenicolous fungi associated with climatic shifts at the Oligocene-Miocene boundary and provides novel insight into evolutionary relationships in this large and diverse family of Lichen-forming ascomycetes. Expand

Monophyletic origins of the metazoa: an evolutionary link with fungi
TLDR
A phylogenetic framework inferred from comparisons of small subunit ribosomal RNA sequences describes the evolutionary origin and early branching patterns of the kingdom Animalia and shows the animal lineage is monophyletic and includes choanoflagellates. Expand
Phylogenetic relationships among Taphrina, Saitoella, and other higher fungi.
TLDR
Taphrina wiesneri and Saitoella complicata form a monophyletic branch that diverged prior to the separation of other ascomycetes and could be accorded to Schizosaccharomyces pombe. Expand
Phylogeny of Discomycetes and early radiations of the apothecial Ascomycotina inferred from SSU rDNA sequence data.
TLDR
A phylogenetic hypothesis recognizes Pezizales as basal and supports Nannfeldt's hypothesis (1932) of a primitive apothecial ascomata with subsequent evolution of perithecial and cleistothecial forms and a most parsimonious tree (MPT) is determined. Expand
Evolutionary relationships within the fungi: analyses of nuclear small subunit rRNA sequences.
TLDR
Nucleotide sequences of the small subunit ribosomal RNA (18S) gene were used to investigate evolutionary relationships within the Fungi, suggesting that covariation of sites may be an important phenomenon in these genes. Expand

TLDR
The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters. Expand
