subdivision ="Glomerales" is an order of
symbiotic fungi within the phylumGlomeromycota .Biology
These Fungi are all
biotrophic mutualists . Most employ thearbuscular mycorrhiza l method of nutrient exchange with plants. They produce large (.1-.5mm) spores (azygospore s andchlamydospore s) with thousands of nuclei.cite book

All members of their phylum were once thought to be related to the
Endogonaceae , but have been found through molecular sequencing data, to be a closer to theDikarya .cite journal | author = A.

The family name
Glomeraceae upon which this order level name is based, was incorrectly spelled 'Glomaceae', hence the order name was incorrectly spelled 'Glomales'. Both are correctable errors, toGlomeraceae and Glomerales, as governed by theInternational Code of Botanical Nomenclature . The incorrect spellings are commonplace in the literature, unfortunately.References
