Article
Full-text available
As part of a comprehensive revision of the Rhizocarpon geographicum species group using molecular and morphological approaches, we examined the name-bearing types of 15 species. We report ambiguities and inconsistencies with the reported features of some type specimens, original descriptions, and circumscriptions employed in keys for the identifica...
Article
Full-text available
We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assembled a six-locus data set including nuclear, mitochondrial and low-copy protein-coding genes from 293 operational taxon...
Article
Full-text available
Here we provide an example of a combined genetic and morphologic approach in a taxonomic re-evaluation in lichen forming fungi to re-solve a log-standing controversy. We used nuclear ITS and mitochondrial SSU rDNA sequences to determine species delimitation in Parmotrema tinctorum, sensu M. Hale. We sampled 50 specimens representing the morphospeci...
Article
Full-text available
Parmelioid lichens are a diverse and ubiquitous group of foliose lichens. Generic delimitation in parmelioid lichens has been in a state of flux since the late 1960s with the segregation of the large, heterogeneous genus Parmelia into numerous smaller genera. Recent molecular phylogenetic studies have demonstrated that some of these new genera were...
