“…However, many Graphidaceae behave differently, in that morphologically or ecologically unique lineages are phylogenetically close to other lineages, such as Cruentotrema , the Topeliopsis -like Chapsa meridensis , and the mazaediate Nadvornikia hawaiiensis ( Mangold et al, 2008 ;Rivas Plata and Lumbsch, 2011 ;Rivas Plata et al, 2012, 2013. Even Diploschistes is nested within Graphidoideae, although its correct position within the subfamily is unresolved ( Martín et al, 2003 ;Fernández-Brime et al, 2011 ;.…”

“…While the family is predominantly epiphytic, a few lineages deviate by their unique ecology, particularly the genus Diploschistes , which is mainly found in subtropical and tropical montane regions on exposed soil and rock substrata and also has a photobiont different from most other Graphidaceae ( Lumbsch, 1989 ;Guderley and Lumbsch, 1996 ;Lumbsch, 2002 ;Lumbsch and Elix, 2003 ). With the data available, ancestral character state analysis indicates a tropical-epiphytic ancestor for Graphidaceae, with lineages such as Diploschistes being derived ( Rivas Plata and Lumbsch, 2011 ). Thus far, it has been diffi cult to test this hypothesis further, since Diploschistes evolved on a very long stem branch and its closest living relative remains unknown ( Martín et al, 2003 ;Fernández-Brime et al, 2011 ;.…”

• Premise of the study: This study elucidates the phylogenetic position of a unique taxon of Graphidaceae occurring on rock in coastal desert areas, assessing its importance for our understanding of the evolution of the largest family of tropical lichenized fungi.• Methods: We used maximum likelihood and Bayesian approaches to reconstruct a three‐gene phylogeny of Graphidaceae and a Bayesian molecular clock approach to estimate divergence dates for major clades, as well as Bayesian ancestral ecogeography state analysis.• Key results: The new genus Redonographa represents a new subfamily, Redonographoideae, sister to subfamily Graphidoideae. Redonographa is exclusively saxicolous and restricted to the American Pacific coast from California to central Chile, including Galapagos. It contains four species: Redonographa chilensis comb. nov., R. saxiseda comb. nov., R. saxorum comb. nov., and R. galapagoensis sp. nov. The genus Gymnographopsis, with a similar ecogeography but differing in excipular carbonization and chemistry, is also included in Redonographoideae, with the species G. chilena from Chile and G. latispora from South Africa. Molecular clock analysis indicates that Redonographoideae diverged from Graphidoideae about 132 million years ago (Ma) in the Early Cretaceous.• Conclusions: The divergence date for subfamilies Redonographoideae and Graphidoideae coincides with the early breakup of Gondwana and ancient origin of the Atacama Desert. However, the common ancestor of Redonographoideae plus Graphidoideae was reconstructed to be tropical‐epiphytic. Thus, even if Redonographoideae is subtropical‐saxicolous, the hypothesis that Graphidoideae evolved from a subtropical‐saxicolous ancestor is not supported.

“…Sequence data of the two species of Cameronia were assembled with sequences of mitochondrial small subunit (mtSSU) and nuclear LSU rDNA downloaded from Genbank (Table 1). Sample preparation, DNA isolation, PCR and direct sequencing were performed as described previously (Mangold et al 2008;Rovas-Plata and Lumbsch 2011). Primers for amplification were: mr SSU1 (Zoller et al 1999) and MSU7 (Zhou and Stanosz 2001) for mtSSU, and AL2R (Mangold et al 2008) and nu-LSU-1125-3' (= LR6) (Vilgalys and Hester 1990) Sequence alignments and phylogenetic analysis…”

The phylogenetic position of the Tasmanian endemic genus Cameronia Kantvilas is studied using partial sequences of nuclear LSU and mitochondrial SSU ribosomal DNA. Monophyly of the genus is supported, as is its placement in Ostropomycetidae, although its position within this subclass remains uncertain. Given the lack of close relatives to Cameronia and its morphological differences compared to other families with perithecioid ascomata in Ostropomycetidae, the new family Cameroniaceae Kantvilas & Lumbsch is proposed.

“…These and other studies have provided strong evidence that many commonly used morphological and anatomical characters traditionally utilized to classify lichenized fungal taxa often are poor predictors of monophyletic groups. By contrast, traits traditionally considered less important in taxonomy are often better indicators of phylogenetic relationships in lichens Blanco et al, 2006;Gueidan et al, 2007; Schmitt et al, 2009a;Rivas-Plata et al, 2011).The Peltigerales is a group of fungi forming symbioses with cyanobacteria, and which earlier often were viewed as "ancient" and featuring many presumably "old" traits (Hawksworth, 1982; Galloway, 1994). These lichens have potentially a substantial impact on the ecosystems they inhabit by fixating atmospheric nitrogen (Cornelissen et al, 2007;Nash, 2008) and many species are rare and threatened by forestry management practices and air pollution.…”

This paper has been peer-reviewed but does not include the final publisher proof-corrections or journal pagination. Citation for the original published paper (version of record):Otálora, M., Aragón, G., Martínez, I., Wedin, M. (2013) Cardinal characters on a slippery slope -A re-evaluation of phylogeny, character evolution, and evolutionary rates in the jelly lichens (Collemataceae s. str.). Evolution, http://dx.doi.org/10. 1016/j.ympev.2013.04.004 Access to the published version may require subscription. Here we reconstruct the phylogeny of Collemataceae using Bayesian and maximum likelihood analyses based on mitochondrial (mtSSU rDNA) and nuclear (nuLSU rDNA, Betatubulin and MCM7) markers of 70 Collemataceae species. We studied the evolution of four morphological and ecological characters traditionally used to delimit genera and infra-generic Molecular Phylogenetics andgroups. Finally, we tested if differences in branch-lengths between clades are due to differences in rates of molecular evolution. Eleven strongly supported groups were recovered in the resulting well-resolved and well-supported phylogeny. The presence/absence of a eucortex, which is currently used as the cardinal character to define genera in the group, does not characterize monophyletic groups corresponding to the genera as currently circumscribed.Ancestral state reconstruction indicates that the most recent common ancestor of the jelly lichens most likely was saxicolous/terricolous, lacked a tomentum, and had transversally septate ascospores. Although the cortex state could not be reconstructed for the ancestor of the family, our observations indicate that a lack of cortex may have an evolutionary advantage in saxicolous/terricolous species in semi-arid environments, as non-corticate species tends to be larger and occur in higher frequency and abundance in such regions, compared to corticate species. A significant evidence for faster evolutionary rates was found in a lineage mainly including taxa that occur in the wet tropics and humid temperate regions, compared to other lineages. We suggest that this can explain the greater diversity of Collemataceae in tropical and humid areas.Key words: Accelerated evolutionary rates, ancestral state reconstruction, Collemataceae, cortex, habitat, lichen-forming fungi. 4 IntroductionLichens are fungi utilizing photosynthetic algae or cyanobacteria for the exploitation of carbohydrates. The symbiotic association allows both the fungal and algal partners to colonize a range of habitats which otherwise would be inhabitable to them. Molecular phylogenetic studies have recently led to significant advances in the understanding of relationships between fungal groups including lichen fungi (Lutzoni et al., 2004; Miadlikowska et al., 2006;Hibbett et al., 2007; Ekman et al., 2008). These and other studies have provided strong evidence that many commonly used morphological and anatomical characters traditionally...
