Fungi that were placed in the Zygomycota are now being reassigned to the Glomeromycota, or the subphyla incertae sedis Mucoromycotina, Kickxellomycotina, the Zoopagomycotina and the Entomophthoromycotina.
Simbiotična povezava med Glomeromycota in rastlinami je najstarejši tip mikorize, ki se je razvil pred 400 milijoni let.
