Classification
Arbuscular mycorrhizal fungi remain in phylum status ( Glomeromycota ) with three classes and five orders (Tedersoo et al. 2018). Along with this advancement, new families and genera have been described (Blaszkowski et al. 2017, 2018,Symanczik et al. 2018, Jobim et al. 2019, Corazon-Guivin et al. 2019). As a result, we currently have 3 classes, 5 orders, 16 families, 44 genera and 317 officially described species (see the global checklist). The most recent phylogenetic tree encompassing most of the taxa in Glomeromycota (Oehl et al. 2011) is available on the page (Figure 1).

However, after this review several taxa were proposed at different levels. Marinho et al. (2014) described the genus Bulbospora in Scutellosporaceae. In the same year Oehl et al. (2014) described Palaeospora in Archaeosporaceae. Furthermore, Sieverding et al. (2014) accommodated the Rhizophagus species in a new genus called Rhizoglomus. Recently two articles propose a new family Pervetustaceae and four new genera Desertispora , Pervetustus, Innospora and Oehlia (Blaszkowski et al. 2017, 2018; Symanczik et al. 2018) (Figure 2 and 3).
