New insights into classification and evolution of the Lecanoromycetes (Pezizomycotina, Ascomycota) from phylogenetic analyses of three ribosomal RNA- and two protein-coding genes.
The phylogenies confirm that ascus morphology cannot be applied consistently to shape the classification of lichen-forming fungi and conclude that a phylogenetic synthesis for a chosen taxonomic group should include a comprehensive assessment of phylogenetic confidence based on multiple estimates using different methods and on a progressive taxon sampling with an increasing number of taxa, even if it involves an increasing amount of missing data.

Molecular systematics and character evolution in the lichen family Ramalinaceae (Ascomycota: Lecanorales)
The Ramalinaceae is the fourth-largest family of lichenized ascomycetes with 42 genera and 913 species exhibiting considerable morphological variation. Historically, generic boundaries in the RamalExpand
Notes for genera: Ascomycota
This work is intended to provide the foundation for updating the ascomycete component of the “Without prejudice list of generic names of Fungi” published in 2013, which will be developed into a list of protected generic names. Expand
One hundred new species of lichenized fungi : a signature of undiscovered global diversity
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. Expand

Taxonomy in a Changing World: Seeking Solutions for a Science in Crisis
The author reveals new insights into classification and evolution of the Lecanoromycetes (Pezizomycotina, Ascomycota) from phylo-genetic analyses of three ribosomal RNA- and two protein-codinggenes. Expand
Studies on Phyllopsora (Ramalinaceae) in Peru
Twenty species of Phyllopsora are recognized in Peru, 8 of which are described as new, and four new combinations are proposed: P. glaucella and P. leucophyllina are new to Peru, while P. swinscowii, and the acid deficient chemotype of P. furfuracea arenew to the neotropics. Expand
