Septoglomus Sieverd., G.A. Sliva & Oehl
| Term | Description |
|---|---|
| Etymology: | Latin, from septum and glomus, with reference to the close relationship this genus has with other glomoid clades |
| Description: | Generally pigmented spores formed singly in soil or in loose clusters; the subtending hypha concolorous with the laminate layer of the spore wall, cylindrical, constricted or slightly funnel-shaped at the spore base; septum often (but not always) formed proximal to the spore base. Forms typical vesicular-arbuscular mycorrhizas. |
| Type species: | Glomus constrictum Trappe |
Spore Development
Oehl et al (2011) erected this genus, together with Simiglomus and Viscospora, as new genera in Glomeraceae and Claroideoglomeraceae, respectively. Redecker et al (2013) accepted Septoglomus, but with some reservations because evidence of phylogenetic separation of the species clade is weak. The other two genera erected in Oehl et al (2011) were rejected. See Redecker et al (2013) for a discussion of the taxonomic and nomenclatural issues surrounding these species. A mess has been created that is going to take some time and effort to sort out.
