“…A small number of LFF not studied here are also known from Basidiomycota, but these are restricted to five isolated lineages within Agaricomycetes, a group that postdates tracheophytes, and whose MRCA was not lichen-forming (Floudas et al, 2012;Kohler et al, 2015). Waters, & Chapman, 2002;Malavasi et al, 2016;Rindi & López-Bautista, 2008). Additionally, LFA are not obligately lichen-forming and may have persisted in the free-living state (Friedl & Büdel, 2008;Mukhtar, Garty, & Galun, 1994 as we know and understand them come later.…”

“…The 95% HPD of the Coccomyxa ‐ Elliptochloris clade slightly pre‐dates tracheophytes as does that of Trentepohliales. However, the ages of these clades likely overestimate the true age of LFA within them, as they contain non‐LFA (and aquatic algae in the case of the Coccomyxa ‐ Elliptochloris clade), suggesting lichenization may have evolved more recently than the MRCA of each clade (López‐Bautista, Waters, & Chapman, ; Malavasi et al, ; Rindi & López‐Bautista, ). Additionally, LFA are not obligately lichen‐forming and may have persisted in the free‐living state (Friedl & Büdel, ; Mukhtar, Garty, & Galun, ).…”

No support for the emergence of lichens prior to the evolution of vascular plants

The early‐successional status of lichens in modern terrestrial ecosystems, together with the role lichen‐mediated weathering plays in the carbon cycle, have contributed to the long and widely held assumption that lichens occupied early terrestrial ecosystems prior to the evolution of vascular plants and drove global change during this time. Their poor preservation potential and the classification of ambiguous fossils as lichens or other fungal–algal associations have further reinforced this view. As unambiguous fossil data are lacking to demonstrate the presence of lichens prior to vascular plants, we utilize an alternate approach to assess their historic presence in early terrestrial ecosystems. Here, we analyze new time‐calibrated phylogenies of ascomycete fungi and chlorophytan algae, that intensively sample lineages with lichen symbionts. Age estimates for several interacting clades show broad congruence and demonstrate that fungal origins of lichenization postdate the earliest tracheophytes. Coupled with the absence of unambiguous fossil data, our work finds no support for lichens having mediated global change during the Neoproterozoic‐early Paleozoic prior to vascular plants. We conclude by discussing our findings in the context of Neoproterozoic‐Paleozoic terrestrial ecosystem evolution and the paleoecological context in which vascular plants evolved.

“…Therefore, most fl oristic and taxonomic studies on tropical subaerial algae were concentrated on Trentepohliales (e.g. Hariot 1889, Thompson & Wujek 1997, Neustupa 2003, Rindi et al 2006a, Rindi & López-Bautista 2008. On the other hand, data on distribution and diversity of other algal groups from tropical subaerial habitats are still extremely scarce.…”

Background and aims -Knowledge on diversity and distribution of algae and cyanobacteria in subaerial habitats still lags behind those of freshwater and marine environments. Notably, data on diversity of microalgae in tropical corticolous habitats are still scarce. We investigated species composition of subaerial epixylic algae and cyanobacteria from two Singaporean rainforest localities. We asked whether there are differences in species composition and alpha-diversity of samples taken in different areas and in different habitat types (bark vs. decaying bare wood). In addition, we asked whether there are differences in species turnover (beta-diversity) among different habitat types and areas. Methods -The cultivation-based approach and the microscopic analysis of populations were used. In total, 20 samples of bark and decaying wood from two forested areas were analyzed. Statistical analyses involved the non-metric multidimensional scaling (NMDS) of species data. Signifi cance of differences in algal composition between groups of samples was evaluated by the non-parametric two-way ANOSIM (Analysis of Similarities) using the crossed design with permutations in blocks. The SIMPER method was used to identify species that characteristically discriminate between habitat types and sampling areas. Key results -In total, 57 species were identifi ed. Green algae (Trebouxiophyceae, Chlorophyceae, Trentepohliales) were dominant, and Cyanobacteria were the second most frequent group. The dominants of the subaerial assemblages differed from corresponding temperate habitats and, in addition, their alpha-diversity was considerably higher. Several green algal morphospecies were characteristic for the bark localities (e.g. Dictyochloropsis spp., Pseudomarvania aerophytica, Printzina effusa and Printzina lagenifera). The alpha-diversity was similar in both habitat types, but the species turnover among samples (beta-diversity) was signifi cantly higher in the decaying wood samples. Conclusions -Tropical corticolous habitats probably harbour higher diversity than corresponding temperate habitats. High beta-diversity of decaying wood illustrates general importance of this substrate for biodiversity of subaerial algae in the tropics.
