Glomeromycota
Glomeromycota (informally glomeromycetes) is one of seven currently recognized divisions within the kingdom Fungi,〔
〕 with approximately 230 described species.〔(Neue Seite 1 )〕 Members of the Glomeromycota form arbuscular mycorrhizas (AMs) with the roots or thalli (e.g. in bryophytes) of land plants. ''Geosiphon pyriformis'' forms an endocytobiotic association with ''Nostoc'' cyanobacteria.〔(New Page 1 )〕 AM formation has not yet been shown for all species. The majority of evidence shows that the Glomeromycota are symbionts with land plants (''Nostoc'' in the case of ''Geosiphon'') for carbon and energy, but there is recent circumstantial evidence that some species may be able to lead an independent existence.〔
〕 The arbuscular mycorrhizal species are terrestrial and widely distributed in soils worldwide where they form symbioses with the roots of the majority of plant species (>80%). They can also be found in wetlands, including salt-marshes, and associated with epiphytic plants.
== Reproduction ==
The Glomeromycota have generally coenocytic (occasionally sparsely septate) mycelia and reproduce asexually through blastic development of the hyphal tip to produce spores〔 (Glomerospores) with diameters of 80–500 μm.〔 In some, complex spores form within a terminal saccule.〔 Recently it was shown that ''Glomus'' species contain 51 genes encoding all the tools necessary for meiosis. Based on these and related findings, it was suggested that ''Glomus'' species may have a cryptic sexual cycle.〔
