Mutually beneficial associations between plants and soil fungi, mycorrhizas, are one of the most important terrestrial symbioses. These partnerships are thought to have propelled plant terrestrialisation some 500 million years ago and today they play major roles in ecosystem functioning. It has long been known that bryophytes harbour, in their living tissues, fungal symbionts, recently identified as belonging to the three mycorrhizal fungal lineages Glomeromycotina, Ascomycota and Basidiomycota. Latest advances in understanding of fungal associations in bryophytes have been largely driven by the discovery, nearly a decade ago, that early divergent liverwort clades, including the most basal Haplomitriopsida, and some hornworts, engage with a wider repertoire of fungal symbionts than previously thought, including endogonaceous members of the ancient sub-phylum Mucoromycotina. Subsequent global molecular and cytological studies have revealed that Mucoromycotina symbionts, alongside Glomeromycotina, are widespread in both complex and simple thalloid liverworts and throughout hornworts, with physiological studies confirming that, in liverworts at least, these associations are mycorrhizal-like, and highlighting important functional differences between Mucoromycotina and Glomeromycotina symbioses. Whether a more prominent role of Mucoromycotina symbionts in plant nitrogen nutrition, as identified in liverworts, extends to other plant lineages, including the flowering plants, is a major topic for future research. The latest finding that ascomycete symbionts of leafy liverworts are not restricted to one fungus, Rhizoscyphus ericae, but include species in the genus Meliniomyces, as shown here in Mylia anomala, together with the recent demonstration that R. ericae forms nutritional mutualisms with the rhizoids of Cephalozia bicuspidata, fill other major gaps in our growing knowledge of fungal associations across land plants.

The International Association of Bryologists (IAB) has been close to my heart during half of a century. Following the establishment of the IAB at the International Botanical Congress in Seattle in 1969, I served as its first secretary-treasurer for eighteen years and helped setting it up. Now, a half-century later, it is a joy and great satisfaction to see a vigorous and healthy IAB continuing on the path of promoting communication and collaboration among the world’s bryologists. It is a pleasure therefore to write a few lines on the history of the organization for this special Golden Jubilee issue of Bryophyte Diversity and Evolution. In doing so, I lean heavily on my account of the early history of the Association (https://bryology.org/history-of-iab/) and my talk on the history of international collaboration at the IAB congress in Madrid (Gradstein 2000).

The moss fossil records from the Paleozoic age to the Eocene epoch are reviewed and their putative relationships to extant moss groups discussed. The incomplete preservation and lack of key characters that could define the position of an ancient moss in modern classification remain the problem. Carboniferous records are still impossible to refer to any of the modern moss taxa. Numerous Permian protosphagnalean mosses possess traits that are absent in any extant group and they are therefore treated here as an extinct lineage, whose descendants, if any remain, cannot be recognized among contemporary taxa. Non-protosphagnalean Permian mosses were also fairly diverse, representing morphotypes comparable with Dicranidae and acrocarpous Bryidae, although unequivocal representatives of these subclasses are known only since Cretaceous and Jurassic. Even though Sphagnales is one of two oldest lineages separated from the main trunk of moss phylogenetic tree, it appears in fossil state regularly only since Late Cretaceous, ca. 70 million years ago (Ma), while earlier they were found twice as small leaf fragments from Lower Jurassic (ca. 200 Ma) and Late Ordovician (ca. 455 Ma). Pleurocarpous mosses appear in fossil state near the border between Jurassic and Cretaceous, although most Cretaceous mosses belong to acrocarps. Only in Eocene amber pleurocarps become more numerous than acrocarps. Some Eocene mosses can be assigned to extant families and sometimes genera, although the majority of Eocene pleurocarps are difficult to identify up to the family, as their morphology often allows placement of a particular specimen into several different families.

The placenta of hornworts is unique among bryophytes in the restriction of transfer cells that are characterized by elaborate wall labyrinths to the gametophyte generation. During development, cells around the periphery of the sporophyte foot elongate, forming smooth-walled haustorial cells that interdigitate with gametophyte cells. Using immunogold labeling with 22 antibodies to diverse cell wall polymers, we examined compositional differences in the developmentally and morphologically distinct cell walls of gametophyte transfer cells and sporophyte haustorial cells in the placenta of Phaeoceros. As detected by Calcofluor White fluorescence, cellulose forms the cell wall scaffolding in cells on both sides of the placenta. Homogalacturonan (HG) and rhamnogalacturonan I (RG-I) pectins are abundant in both cell types, and haustrorial cells are further enriched in methyl-esterified HGs. The abundance of pectins in placental cell walls is consistent with the postulated roles of these polymers in cell wall porosity and in maintaining an acidic apoplastic pH favorable to solute transport. Xyloglucan hemicellulose, but not mannans or glucuronoxylans, are present in cell walls at the interface between the two generations with a lower density in gametophytic wall ingrowths. Arabinogalactan proteins (AGPs) are diverse along the plasmalemma of placental cells and are absent in surrounding cells in both generations. AGPs in placental cell walls may play a role in calcium binding and release associated with signal transduction as has been speculated for these glycoproteins in other plants. Callose is restricted to thin areas in cell walls of gametophyte transfer cells. In contrast to studies of transfer cells in other systems, no reaction to the JIM12 antibody against extensin was observed in Phaeoceros.

In 1969, an international group of bryologists established an association welcoming everyone seeking to further our knowledge on the biology of bryophytes. Fifty years later, the International Association of Bryologists (IAB) has slightly over 350 active members worldwide. Over the past decades, IAB has promoted bryology by establishing bryonet, a forum for discussions and questions, managed by Dr. Janice Glime, by publishing a regular newsletter, The Bryological Times sharing information about various developments in bryology, by publishing major reviews on specific subjects through the Advances in Bryology, by disseminating contributions to the diversification of bryophytes through Bryophyte Diversity and Evolution, by organizing biennial meetings, including in association with the sexennial International Botanical Congress, and by honoring colleagues for their achievements and stimulating research through grants. All these are made possible through the exemplary commitment by colleagues serving on the council, the editorial boards and the various ad hoc adjudication committees. To all, my and the members’ sincere gratitude.

A Cheilolejeunea species with peculiar leaf shape is described from Madagascar, as new to science, which belongs to Sect. Cyrtolejeunea. This encouraged the author to reinvestigate other African members of this section, and to transfer the former described Neurolejeunea breutelii var. africana into the genus of Cheilolejeunea sect. Cyrtolejeunea under the name of Cheilolejeunea shevockii and to re-establish the identity of Cheilolejeunea ulugurica. As a consequence, three species of the ten members of Sect. Cyrtolejeunea occur in Africa, while the genus Neurolejeunea remains restricted only to the Neotropics.

Inter-relationship among the cryptic species in the genus Conocephalum Hill was studied using rbcL + rps4 sequences as well as morphological features. Samples used in this study originated from 1) the long-cultivated strains from Europe, North America, and Asia used for previous allozymes and molecular studies and 2) newly gathered plants mainly from Japan and Taiwan used for both molecular and morphological study. For the C. conicum/ salebrosum complex, a total of six species were confirmed, including a new species previously recognized as R type or Chemotype III (Toyota 1994, Kim et al. 2001 Miwa et al 2009). The R type has unique volatile component and morphological features; presence of Methyl cinnamate in natural conditions and absence of mucilage cavity in the central part of thallus. As for the C. japonicum complex, three cryptic species formerly recognized by allozymes and molecular analyses were confirmed. These three species are remotely distant from all the members of the C. conicum/ salebrosum complex. Conocephalum japonicum is here reinstated in the genus Sandea Lindb., as Sandea japonica Steph. ex Yoshin.
