The phylogenetic placement of Ostropales within Lecanoromycetes (Ascomycota) revisited

Molecular data support placement of Cameronia in Ostropomycetidae (Lecanoromycetes, Ascomycota)

“…The ML tree and the tree from the B/MCMC tree sampling were almost identical, with no differences in well-supported clades. Furthermore, taxon sampling was very similar to that of previous studies focusing on the phylogeny of Ostropomycetidae (Baloch et al 2010;Lumbsch et al 2007a;Lumbsch et al 2007b;Wedin et al 2005). Thus, only a simplified ML tree, with samples of well-supported families, genera or generic groups collapsed, is shown here (Fig.…”

“…Phylogenetic placement of Cameronia as inferred from a concatenated alignment of mtSSU and nuLSU DNA sequences. This is a simplified cartoon of the optimal tree under maximum likelihood with well supported families and species groups collapsed that were shown in previous studies (Baloch et al 2010;Lumbsch et al 2007a;Lumbsch et al 2007b;Wedin et al 2005). Asterisks indicate branches with likelihood bootstrap support values above 70% and posterior probabilities equal or above 0.95.…”

“…1 nuLSU mtSSU e+Ostropomycetidae (Lumbsch et al 2007a;Miadlikowska et al 2006;Spatafora et al 2006;Wedin et al 2005). 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).…”

A molecular phylogeny of the Lecanora varia group, including a new species from western North America

“…As the backbone of clade three is still poorly supported, more gene loci should be included in future studies. Finally, taxon sampling may have to be improved to come to a stable systematic solution for the Lecanora varia group, as has been demonstrated in other taxonomic groups (Lumbsch et al 2007). In order to achieve this, intense field work, even in the comparatively well-explored regions of Europe and western North America, will be necessary.…”

Journey from the West: Did tropical Graphidaceae (lichenized Ascomycota: Ostropales) evolve from a saxicolous ancestor along the American Pacific coast?

“…However, since the tropical-epiphytic subfamily Fissurinoideae is sister to Redonographoideae plus Graphidoideae, the ancestral ecogeography state analysis employed here rejects this hypothesis and instead indicates that the subtropical-saxicolous ecogeography evolved secondarily within the subfamily. This is supported by the fact that Graphidaceae, and hence Redonographoideae, are nested deep within the Ostropales, which are predominantly wet-tropical ( Kauff and Lutzoni, 2002 ;Lumbsch et al, 2007 ;Baloch et al, 2010 ). Also, the early divergence dates of Graphidaceae as a whole agree with the early evolution of extensive tropical rain forests in the Early to Middle Jurassic (E. Rivas Plata et al, unpublished manuscript ), and three of the four subfamilies (Fissurinoideae, Gomphilloideae, Graphidoideae) have largely or entirely retained this ecology.…”
