TL;DR: A total of 100 new species of lichenized fungi are described, representing a wide taxonomic and geographic range, and emphasizing the dire need for taxonomic expertise in lichenology.
Journal ArticleDOI
The delimitation of Antarctic and bipolar species of neuropogonoid Usnea (Ascomycota, Lecanorales): a cohesion approach of species recognition for the Usnea perpusilla complex
TL;DR: A phylogenetic analysis revealed three related complexes of mainly asexual lineages arranged around three fertile Usnea species: U. perpusilla, which could also delimit an undescribed fertile species with yellow apothecia and a new asexual species from the High Andes.
Journal ArticleDOI
Lichen fungi have low cyanobiont selectivity in maritime Antarctica
Nora Wirtz,H. Thorsten Lumbsch,H. Thorsten Lumbsch,T. G. Allan Green,Roman Türk,Ana Pintado,Leopoldo G. Sancho,B. Schroeter +7 more
TL;DR: The Antarctic lichen species here did not use species-specific cyanobionts; this could be because of a selection pressure in this extreme environment, which results in selection against photobiont specificity, a selection Pressure that may be more important for lichen distribution than the effect of cold temperatures on metabolism.
Journal ArticleDOI
Phylogenetic and morphological analysis of Antarctic lichen-forming Usnea species in the group Neuropogon
Fabian A. Seymour,Peter D. Crittenden,Nora Wirtz,Dag Olav Øvstedal,Paul S. Dyer,H. Thorsten Lumbsch +5 more
TL;DR: Phylogenetic analyses indicated that species circumscription in the Neuropogon group needs revision, with the principal species being non-monophyletic, and none of the morphological characters, or groups of characters, used in this study proved to be completely unambiguous markers for a single species.
Journal ArticleDOI
Using haplotype networks, estimation of gene flow and phenotypic characters to understand species delimitation in fungi of a predominantly Antarctic Usnea group (Ascomycota, Parmeliaceae)
TL;DR: Examination of species boundaries in the predominantly Antarctic and South American group of neuropogonoid species of the lichen-forming fungal genus Usnea identified several clades that were significantly associated with phenotypic characters, but did not necessarily agree with current species circumscriptions.
