Glomeromycota
Captions available
The idea
Glomeromycota is defined by an obligate mycorrhizal partnership with plant roots, reproduces without a sexual cycle, and cannot survive apart from a root.
In practice
Nearly all Glomeromycota species form arbuscular mycorrhizae, exchanging soil minerals for plant-supplied carbohydrates through a hyphal structure inside root cells.
Where people slip
Unlike most fungal phyla, Glomeromycota's defining criterion is ecological dependence, not a distinct spore structure.
