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 taxonomic(More)
Graphis scripta, or script lichen, is a well-known species of crustose lichenized fungi, widely distributed in the temperate region of the Northern Hemisphere. It is now considered to be a species complex, but because of the lack of secondary chemistry and paucity of measurable morphological characters, species delimitation within the complex has been(More)
A new species, Aspicilia tibetica Sohrabi & Owe-Larss., is described from Tibet, where it grows on soil and plant debris at altitudes between 4,600 and 5,400 m, and where it seems to be rather commonly distributed. It is characterized by a crustose, white thallus, 8-spored asci with small, globose to ellipsoid ascospores, a brown epihymenium, and(More)
We present ataxonomic revision of the ‘manna lichens’ based on morphological, chemical, ecological and molecular data. A large number of herbarium specimens and fresh collections were examined. Phylogenetic analyses were performed using nuclear ribosomal (nrITS, nrLSU) and mitochondrial small subunit (mtSSU) sequences. Some notable phenotypic characters(More)
Identifying factors that influence species interactions is central to research in symbiotic systems. While lichens represent iconic models of symbiosis and play important roles in understanding the biology of symbiotic interactions, patterns of interactions in lichen symbionts and mechanisms governing these relationships are not well characterized. This is(More)
