TL;DR: Most endangered species are restricted to the Atlantic Rainforest of southeastern Brazil, which is the diversity and endemism centre for mosses and liverworts.
Abstract: The bryoflora of Brazil comprises 1,524 species, 117 families, and 413 genera (11 hornworts, 633 liverworts, and 880 mosses). The most diverse families of liverworts are: Lejeuneaceae (285 species), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae and Metzgeriaceae (26 each), Lophocoleaceae (18), Aneuraceae (15), and Calypogeiaceae (13); while, for the mosses, we have: Sphagnaceae (83 species), Fissidentaceae (65) Pottiaceae (63), Dicranaceae (54), Bryaceae and Sematophyllaceae (53 each), Orthotrichaceae and Pilotrichaceae (51 each), Calymperaceae (48), and Hypnaceae (28). These large groups account for 71% of the Brazilian bryophyte species. Lejeuneaceae and Sphagnaceae are the families with highest number of endemic taxa (54 and 60 species). The Atlantic Rainforest presents the greatest number of species (1,337), followed by the Amazon Rainforest (570) and Cerrado (478). The highest number of endemic species (242) is associated with the Atlantic Rainforest, where the Dense Ombrophilous Forest concentrates 73% of the species with 62% endemism. The Southeastern region is the most diverse in number of species (1,228) and with more endemism (219). Most endangered species are restricted to the Atlantic Rainforest of southeastern Brazil, which is the diversity and endemism centre for mosses and liverworts. The information currently presented by the Brazilian List is close to the real bryophyte diversity found in the country.

TL;DR: The phylogeny indicates that KurZia, as defined by the presence of Microlepidozia-type branching, is polyphyletic, and 6 species previously assigned to Kurzia are transferred to Telaranea, and Progressive reduction in morphological complexity as a central evolutionary tendency in the genus is strongly supported.
Abstract: Telaranea is the third largest genus of Lepidoziaceae, after Bazzania (over 450 species) and Lepidozia (over 300 species). In this monograph, 98 species of Telaranea are recognized, 62 of which are extra-Australasian. Included are 11 new species, 2 new varieties, 27 new combinations (25 species and one variety), and one new name. New taxa are fully described and illustrated. Two subgenera of Telaranea are recognized (subg. Acrolepidozia, subg. Telaranea), and 7 sections within subg. Telaranea (sect. Neolepidozia (Fulf. & J. Tayl.) Engel & Merr. comb. nov., sect. Cancellatae Engel & Merr., sect. Ceraceae Engel & Merr. sect. nov., sect. Tricholepidozia (Schust.) Engel & Merr. comb. nov., sect. Transversae Engel & Merr., sect. Telaranea, sect. Tenuifoliae (Schust.) Engel & Merr. comb. nov.). A major part of this work is devoted to a phylogenetic study of the genus Telaranea, with a discussion of character evolution in the genus and a reconstruction of ancestral character states. An ancestral area an...

TL;DR: The liverworts and hornworts of New Caledonia is a sequel to the recent catalogue of the mosses and accepts 464 species and 18 infraspecific taxa, in 104 genera and 39 families, which is more similar to that of Indomalesia than of Australasia.

TL;DR: Divergence time estimates are obtained for a large family of leafy liverworts; the Lepidoziaceae (Jungermanniidae), and it is shown that, although there is great potential in synthetic dating analyses of sequence data, missing sequences can reduce the reliability of estimates, and that calibration priors should be interpreted with caution.
Abstract: Estimating the temporal origins of lineage diversity adds an important dimension to understanding diversity generating processes. In lineages with a sparse fossil record, molecular phylogenetic methods provide a means for estimating divergence times. In the present study, we use publicly available sequence data from the chloroplast genome of liverworts to simultaneously estimate significant divergence dates across all classes and orders of liverworts (Marchantiophyta). We show that, although there is great potential in synthetic dating analyses of sequence data, missing sequences can reduce the reliability of estimates, and that calibration priors should be interpreted with caution. Using the liverwort dataset as a broad outgroup, we obtain the first divergence time estimates for a large family of leafy liverworts; the Lepidoziaceae (Jungermanniidae). The Lepidoziaceae originated in the early Cretaceous with subsequent establishment of main lineages in the late Cretaceous. Divergence time estimates are consistent with Cenozoic diversification in Lepidozia, Telaranea, and Bazzania. Evidence was found for similar patterns of ancient origins followed by Cenozoic diversification in Ricciaceae (Marchantiopsida), Pelliaceae and Fossombroniaceae (Pelliidae), and Metzgeriaceae (Metzgeriidae), and adds to reports of similar patterns in Lejeuneaceae (Jungermanniidae, Porellales), and Plagiochilaceae (Jungermaniidae, Jungermanniales). The liverworts might be the living relatives of one of the earliest groups of land plants, but much of the extant diversity has evolved in the Cenozoic. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ••, ••‐••.

TL;DR: DiOC6 (3) offers a rapid means for identifying intracellular ascomycetous mycorrhizas and for determining the distribution of living hyphae within these associations and is a vital stain of fungal cytoplasm.
Abstract: SUMMARY The lipophilic fluorochrome 3,3'dihexyloxacarbocyanine iodine [DiOC6(3)], previously used to visualize mitochondria and ER in animal and plant cells, when applied at concentrations of 0-01-5 ,tg ml-l selectively stains ascomycetous hyphae in ericaceous roots and in the rhizoids of liverworts in the families Lepidoziaceae (both tropical and temperate species), Calypogeiaceae, Adelanthaceae, Cephaloziaceae and Cephaloziellaceae. Basidiomycetes forming endophytic associations with liverworts and ectomycorrhizas in seed plants, are stained with DiOC6(3) only at concentrations at and above 50 ,tg ml-'. VA mycorrhizal fungi in liverworts, pteridophytes and angiosperms fail to stain. Hyphae of the ericoid mycorrhizal fungus, Hymenoscyphus ericae, grown in axenic culture, are stained with much lower concentrations of DiOC6(3) than are those of a range of ectomycorrhizal fungi, an orchid fungus and Oidiodendron griseum which has been reported occasionally to form ericoid mycorrhizal associations. In contrast to other fluorescent probes that recognize fungal wall components, DiOC6(3) is a vital stain of fungal cytoplasm. Greater membrane permeability, compared to that in other fungi, is the likely basis for the selective staining of Hymenoscyphus ericae and the root and rhizoid-inhabiting ascomycetes with this dye. DiOC6(3) offers a rapid means for identifying intracellular ascomycetous mycorrhizas and for determining the distribution of living hyphae within these associations.
