Neuropogonoid species in the lichen-forming fungal genus Usnea exhibit great
morphological variation that can be misleading for delimitation of species. We specifically …

Species delimitations in the predominantly Antarctic and South American group of
neuropogonoid species of the lichen-forming fungal genus Usnea are poorly understood …

Advancements in molecular genetics have revealed that hybridization may be common
among plants, animals, and fungi, playing a role in evolutionary dynamics and speciation …

Lichens are symbiotic associations consisting of a fungal (mycobiont) and one or more
photosynthetic (photobionts) partners and are the dominant component, and most important …

Species richness is not evenly distributed across the tree of life and a limited number of
lineages comprise an extraordinarily large number of species. In lichen-forming fungi, only …

Abstract Aim The Southern Ocean landmasses have intrigued biologists for centuries
because they share many taxonomic groups. Such disjunct taxa can provide insight into …

Aim The relative importance of long‐distance dispersal versus vicariance in determining the
distribution of lichen‐forming fungi remains unresolved. Here, we examined diversity and …

Aim The homogenisation of historically isolated gene pools has been recognised as one of
the most serious conservation problems in the Antarctic. Lichens are the dominant …

In traditional morphology-based concepts many species of lichenized fungi have world-wide
distributions. Molecular data have revolutionized the species delimitation in lichens and …

Biological processes such as hybridization, incomplete lineage sorting and gene flow can
obscure the recognition of distinct evolutionary lineages, particularly in groups of organisms …
