A mycotroph is a plant that gets all or part of its carbon, water, or nutrient supply through symbiotic association with fungi. A holomycotroph gets all its nutrition solely from a mycorrhizal symbiosis. The term can refer to plants that engage in either of two distinct symbioses with fungi:Many mycotrophs have a mutualistic association with fungi in any of several forms of mycorrhiza. The majority of plant species are mycotrophic in this sense. Examples include Burmanniaceae. Some mycotrophs are parasitic upon fungi in an association known as myco-heterotrophy.
