Article
Full-text available
Mycocaliciales comprise non-lichenized either saprotrophic or lichenicolous fungi which occur in temperate and tropical regions. The mazaediate, saprotrophic and monospecific genus, Pyrgidium, is currently assigned to this order, yet the phylogenetic placement of the genus has remained uncertain due to the absence of molecular data. In order to inv...

Lichens are well known as pioneer organisms colonizing bare surfaces such as rocks and therefore have been hypothesized to play a role in the early formation of terrestrial ecosystems. Given the rarity of fossil evidence, our understanding of the evolutionary history of lichen-forming fungi is primarily based on molecular dating approaches. These s...
Article
Full-text available
Lichens are symbiotic associations resulting from interactions among fungi (primary and secondary mycobionts), algae and/or cyanobacteria (primary and secondary photobionts), and specific elements of the bacterial microbiome associated with the lichen thallus. The question of what is a species, both concerning the lichen as a whole and its main fun...
Article
Subandine and high Andean forests are often dominated by oak trees and these are recognized as suitable phorophytes for diverse epiphyte communities. Among the latter, lichens in the upper strata appear to be understudied. Here, we report the discovery of two new species of Astrothelium (Trypetheliaceae), a diverse genus of tropical crustose lichen...
