The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualistic associations such as mycorrhizae and lichens have evolved in this group, which are regarded as key innovations that supported the evolution of land plants. Only a few attempts have been made to date the origin of Ascomycota lineages by using molecular(More)
Recent studies have provided evidence for pulses in the diversification of angiosperms, ferns, gymnosperms, and mosses as well as various groups of animals during the Cretaceous revolution of terrestrial ecosystems. However, evidence for such pulses has not been reported so far for liverworts. Here we provide new insight into liverwort evolution by(More)
In this study, we evaluate the impact of fossil assignments and different models of calibration on divergence time estimates carried out as Bayesian analyses. Estimated ages from preceding studies and liverwort inclusions from Baltic amber are used as constraints on a molecular phylogeny of Cephaloziineae (Jungermanniopsida) obtained from sequences of two(More)
BACKGROUND Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history and diversification through time are largely unknown. METHODOLOGY AND RESULTS We employed sequences of two chloroplast regions (trnL-trnF, rbcL) and(More)
A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera(More)
The Neotropical genus Bromeliophila includes two species that grow exclusively in the water-filled leaf axils of Bromeliaceae. Phylogenetic analyses of a three marker dataset (chloroplast genome rbcL gene and trnL-F region, and nuclear ribosomal ITS1-5.8S-ITS-2 region) confirmed the monophyly of Bromeliophila and provided evidence for a sister relationship(More)
The Lophocoleaceae-Plagiochilaceae-Brevianthaceae clade is a largely terrestrial, subcosmopolitan lineage of jungermannialean leafy liverworts that may include significantly more than 1000 species. Here we present the most comprehensively sampled phylogeny available to date based on the nuclear ribosomal internal transcribed spacer region and the(More)
Cephaloziaceae represent a subcosmopolitan lineage of largely terrestrial leafy liverworts with three-keeled perianths, a reduced seta, capsules with bistratose walls, filamentous sporelings, large, thin-walled cells, and vegetative distribution by gemmae. Here we present the most comprehensively sampled phylogeny available to date based on the nuclear(More)
