In order to evaluate substrate dependence of the symbiotic fungal associations in leafy liverworts (Jungermanniopsida), 28 species out of 12 families were investigated by transmission electron microscopy and molecular methods. Samples were obtained from the diverse substrates: from naked soil, from the forest floor on needle litter, from between peat moss,(More)
Mycorrhizas of vascular plants and mycorrhiza-like associations of liverworts and hornworts are integral parts of terrestrial ecosystems, but have rarely been studied in tropical mountain rain forests. The tropical mountain rain forest area of the Reserva Biolo´gica San Francisco in South Ecuador situated on the eastern slope of the Cordillera El Consuelo(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)
A total of 35 population samples of the liverwort genera Aneura (A. pinguis) and Riccardia (R. latifrons, R. multifida, and R. palmata) were sampled from diverse habitats and geographical provenances in Germany, Austria, and Switzerland. Light and transmission electron microscopy were used to characterise the morphological features of the associations, and(More)
Aneura pinguis (Aneuraceae) is a cosmopolitan thalloid liverwort that shows a specific mycorrhiza-like interaction with basidiomycetes. To date, tropical specimens have not been studied in great depth. Samples of A. pinguis were collected from 48 individuals in one plot in South Ecuador and 54 individuals in five European countries. Light and transmission(More)
to his new genus. A molecular phylogenetic study confirmed this treatment (Preussing et al. 2010). However, two recently recognized varieties from Australia and a species from New Zealand were not transferred as they do not occur in the area treated by the monograph (Furuki 1991). They are transferred as follows: Formal treatment The format of this note(More)
