Journal ArticleDOI
High performance thin layer chromatography (HPTLC), an improved technique for screening lichen substances.
TL;DR: High performance thin layer chromatography (HPTLC) is an improved technique for screening lichen substances and it is shown that it can improve the quality of results and reduce the number of errors.
Journal ArticleDOI
Phylogenetic generic classification of parmelioid lichens (Parmeliaceae, Ascomycota) based on molecular, morphological and chemical evidence

TL;DR: An overview of current knowledge of the major clades of all parmelioid lichens is given and 27 genera within nine main clades are accepted, including 31 of 33 currently accepted parMelioid genera (and 63 of 84 accepted genera of Parmeliaceae).
Journal ArticleDOI
Testing morphology-based hypotheses of phylogenetic relationships in Parmeliaceae (Ascomycota) using three ribosomal markers and the nuclear RPB1 gene.
Ana Crespo,H. Thorsten Lumbsch,Jan-Eric Mattsson,Oscar Blanco,Pradeep K. Divakar,Kristina Articus,Elisabeth Wiklund,Paulina A. Bawingan,Mats Wedin +8 more
TL;DR: Testing morphology-based groupings using DNA sequence data from 120 taxa that include 59 genera and represent the morphological and chemical diversity in Parmeliaceae supports morphological characters as important for the identification of monophyletic clades within the family.
Journal ArticleDOI
Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi

TL;DR: The phylogenetic hypothesis supports the independent origin of lichenicolous fungi associated with climatic shifts at the Oligocene-Miocene boundary and provides novel insight into evolutionary relationships in this large and diverse family of Lichen-forming ascomycetes.
Journal ArticleDOI
Ribosomal DNA and β-tubulin data do not support the separation of the lichens Usnea florida and U. subfloridana as distinct species
TL;DR: The lichens Usnea florida and U. subfloridana have since long been recognised as distinct species, but they show many similarities in morphology, but have different reproductive strategies.
