“…Indeed, cytologically the associations in gametophytes of lycopods and basal ferns (Duckett & Ligrone 1992, 2005Schmid & Oberwinkler 1993 are virtually identical to those in the liverworts. The near basal position of the Marchantiopsida and Metzgeriidae in embryophyte phylogeny and the widespread occurrence of glomeromycetes within them fit the notion that the co-evolution of liverworts with these fungi predated the appearance of arbuscular mycorrhizas in tracheophytes (Kottke & Nebel 2005;Wang & Qiu 2006). However, the fact that members of Glomus Group A, a derived clade within the genus that also forms mycorrhizas in tracheophytes, are widespread in these liverwort taxa that are widely separate both geographically and phylogenetically led Selosse (2005) to an alternative hypothesis: host shifting from tracheophytes to liverworts.…”

“…The recent discovery of mycorrhizal genes, probably homologous across all lineages of land plants (Wang et al 2010, but also see the critique by Bonfante & Selosse 2010), provides a striking reaffirmation of the notion first proposed by Pirozynski & Malloch (1975) and variously elaborated subsequently with a liverwortcentred-focus (Selosse & LeTacon 1998;Nebel et al 2004;Kottke & Nebel 2005) that fungal symbioses rank alongside stomata, cuticles, matrotrophy and conducting tissues as one of the key innovations of land plants. Since bryophytes are now firmly fixed at the base of the land plant tree of life, studies on their fungal symbioses probably represent the most likely source for new insights into the evolution of this phenomenon.…”

Fungal symbioses are one of the key attributes of land plants. The twenty first century has witnessed the increasing use of molecular data complemented by cytological studies in understanding the nature of bryophyte-fungal associations and unravelling the early evolution of fungal symbioses at the foot of the land plant tree. Isolation and resynthesis experiments have shed considerable light on host ranges and very recently have produced an incisive insight into functional relationships. Fungi with distinctive cytology embracing short-lived intracellular fungal lumps, intercellular hyphae and thick-walled spores in Treubia and Haplomitrium are currently being identified as belonging to a more ancient group of fungi than the glomeromycetes, previously assumed to be the most primitive fungi forming symbioses with land plants. Glomeromycetes, like those in lower tracheophytes, are widespread in complex and simple thalloid liverworts. Limited molecular identification of these as belonging to the derived clade Glomus Group A has led to the suggestion of host swapping from tracheophytes. Ascomycetes, all identified to date as Rhizoscyphus ericae and having an extremely wide host range extending into the Ericales, occur in the rhizoids of a range of leafy liverwort families that are sister to the Schistochilaceae, where the fungus induces rhizoid branching and septation. Dating of the Schistochilaceae suggests that these liverwort rhizoid associations predated ericoid mycorrhizas. A more restricted distribution of basidiomycetes, all identified as members of the genus Sebacina, is interpreted as a secondary acquisition in leafy liverworts following the loss of ascomycetes. Unlike the latter and ectomycorrhizal basidiomycetes in tracheophytes, these are host specific. Whereas there is no evidence of host digestion for either the ascomycetes or basidiomycetes in leafy liverworts, basidiomycetes in the Aneuraceae display regular colonization and digestion cycles. Considerable molecular diversity in the aneuracean fungi, mainly in the genus Tulasnella with occasional sebacinoids, mirrors the same in the host liverworts. Nesting of the only mycoheterotrophic liverwort Cryptothallus within Aneura is congruent with the phylogeny of the endophytes. Glomeromycete fungi have been identified in Phaeoceros and Anthoceros whereas Dendroceros, Megaceros and Nothoceros lack endophytes but the distribution of fungi across hornworts has yet to be explored. In contrast to liverworts and hornworts, there is no evidence of mycorrhiza-like associations in mosses. Claims that the fossil Prototaxites was a fossil fungus-associated liverwort are discounted.

A historical retrospect and a taxonomic update will deal with Sebacina s.l. and s.str., Craterocolla, Efibulobasidium, Serendipita, Trem ell odendron, Trem ell oscypha, Tremellostereum, and Piriformospora, the Sebacinaceae, and the Sebacinales. Phylogenetic hypotheses for the order and subordinal taxa are discussed, including environmental sequence taxa. The cryptic biodiversity in Sebacinales is extensive but mostly unresolved with respect to the species involved.

“…Most plant families are able to form this type of relationship (Brundrett 2009;Wang & Qiu 2006), including nonvascular plants such as liverworts Ligrone et al 2007;Fonseca et al 2009). In the case of such plants, the relationships is referred to as arbuscular mycorrhiza-like (AML) symbiosis Moreira & Siqueira 2006;Souza et al 2010;Kottke & Nebel 2005, Humphreys et al 2010.…”

In this study, we evaluated the growth of the liverwort Lunularia cruciata, inoculated or not with the arbuscular mycorrhizal fungi (AMF) Glomus proliferum (15 spores per Petri dish), in Strullu-Romand Variant (SRV) medium modified and enriched with humic acid (HA) at different concentrations (0, 20, 40 and 80 mg C L −1 ), as well as the sporulation of the AMF. We assessed the absolute growth rate (AGR) and relative growth rate (RGR) at inoculation, as well as at 7, 14, 21, 28, 43, 52 and 60 days after inoculation (DAI), whereas we assessed sporulation at 25, 43, 60 and 70 DAI. The main determinant of L. cruciata growth was the presence of AMF. With and without G. proliferum inoculation, respectively, the AGR peaked at 39 and 42 DAI, and the RGR was 0.0474 and 0.0387 cm 2 cm −2 d −1 . Doses of 20 and 80 mg C L −1 of HA had a positive influence on the growth of L. cruciata. With and without HA, respectively, the AGR peaked at 38 and 39 DAI, and the RGR was 0.0484 and 0.0422 cm 2 cm −2 d −1 . The sporulation of G. proliferum, which was as high as 199 spores plate −1 , was influenced by HA, especially at 20 and 80 mg C L −1 .
