The classification proposed by Schüssler & Walker (2010) was also based on genetic characters covering the small ribosomal RNA unit (SSU), the largest subunit (LSU) as well as the ITS region. The classification was published as a PDF file and presented on a website (www.amf-phylogeny.com). The proposal was characterized by the rearrangement of species of the genus Glomusand the proposal of new families. In this classification, some species were referred to as “of uncertain position” since many of them are not found in pure or mixed cultures, and thus, cannot be evaluated by genetic characters to determine their phylogenetic position.
