Description
Summary:Based on molecular phylogenetic analyses, and also considering morphological characters, four new families are separated from the family Glomeraceae within the order Glomerales and the class Glomeromycetes. The revised family Glomeraceae comprises only four genera: the type genus <i>Glomus</i>, <i>Complexispora</i>, <i>Sclerocarpum</i> and <i>Simiglomus</i>. Septoglomeraceae fam. nov. comprises, besides <i>Septoglomus</i>, <i>Funneliformis</i>, <i>Funneliglomus</i>, <i>Blaszkowskia</i> and <i>Viscospora</i>. Sclerocystaceae fam. nov. is represented by the type genus <i>Sclerocystis</i> but also by <i>Halonatospora</i>, <i>Oehlia</i>, <i>Parvocarpum</i>, <i>Rhizoglomus</i> and <i>Silvaspora</i>. Kamienskiaceae fam. nov. encompasses <i>Kamienskia</i>, <i>Microkamienskia</i> and <i>Epigeocarpum</i>. Finally, Dominikiaceae fam. nov. includes the genera <i>Dominikia</i>, <i>Macrodominikia</i> gen. nov., <i>Microdominikia</i>, <i>Nanoglomus</i> and <i>Orientoglomus</i>. The genera <i>Oehlia</i> and <i>Halonatospora</i> form two other clades well separated from <i>Silvaspora</i>, <i>Sclerocystis</i> and <i>Rhizoglomus</i> and might represent two further families within Glomerales. This deeper separation is, in our opinion, fully supported by molecular phylogeny, but in view of the low numbers of taxa, the separation is not yet proposed at this stage of research progress.
