The sister group relation of Parmeliaceae (Lecanorales, Ascomycota)
Mycologia, 2007The family Parmeliaceae (Lecanorales, Ascomycota) is possibly the largest, best known and most thoroughly studied lichen family within its order. Despite this fact the relationship between Parmeliaceae and other groups in Lecanorales is still poorly known.

A Conspectus of the Genus Phacopsis (Lecanorales)
The Bryologist, 1995Phacopsis is a genus of lichenicolous fungi distributed worldwide on members of the Parmeliaceae s. ampl. The genus is characterized using current concepts, and its delimitation and family position are discussed. Thirteen taxa are accepted and a key supplied together with new data on their host specificity and distribution.

Chemosyndromes in the lichen genus Teloschistes (Teloschistaceae, Lecanorales)
Mycological Progress, 2002The secondary metabolites of 150 specimens belonging to 29 species of Teloschistes were analysed with HPLC. Seven anthraquinones were detected of which parietin dominated with minor proportions of emodin, teloschistin, fallacinal and parietinic acid. The depsidones vicanicin, caloploicin, and isofulgidin occurred together with some compounds of unknown

Three Squamulose Species of Rimularia (Lecanorales)
The Bryologist, 2002Three species are placed in the lichen genus Rimularia Nyl.: R. michoacanensis (B. de Lesd.) comb. nov., R. paradoxa Timdal & W. A. Weber sp. nov., and R. subconcava (H. Magn.) comb. nov. The species differ from the previously recognized species of the genus in having squamulose thalli and filiform pycnoconidia.

Phylogeny of bipolar Cladonia arbuscula and Cladonia mitis (Lecanorales, Euascomycetes)
Molecular Phylogenetics and Evolution, 2003Phylogenetic relationships and levels of geographic differentiation of two closely related bipolar taxa, Cladonia arbuscula and Cladonia mitis, were cladistically examined with ITS regions, SSU rDNA introns, partial beta-tubulin, and partial glyceraldehyde 3-phosphate dehydrogenase (GAPDH) genes. In the combined analysis of the four genes, C. arbuscula

The cetrarioid core group revisited (Lecanorales: Parmeliaceae)
The Lichenologist, 2011AbstractThe cetrarioid core group has been the focus of numerous taxonomic and phylogenetic studies in recent years, yet the phylogenetic resolution and support among these clades remains unclear. Here we use four commonly employed loci to estimate if their use increases phylogenetic resolution and support.

Where does Lecanora Demissa (Ascomycota, Lecanorales) Belong?
The Lichenologist, 1999Abstract Lecanora demissa (Körb.) Zahlbr. is a crustose, lobate lichen that produces soredia and conidiomata but no apothecia. Its placement in Lecanora has long been questioned but nothing better has been proposed. We have studied the nuclear rDNA of the ITS regions and the SSU of L. demissa.

Problems in Lecanorales Systematics
1994A further attempt to circumscribe the order Lecanorales is made. So far the only distinguishing characters for lecanoralean fungi are connected with the ascus-type, the peculiarities of which are pointed out. Some other features which might influence details in ascus structure are discussed as well as some problems of character selection and their ...
