Epipogium aphyllumis a rare Eurasian achlorophyllous forest orchid known to associate with fungi that form ectomycorrhizas, while closely related orchids of warm humid climates depend on wood‐ or litter‐decomposer fungi. We conducted13C and15N stable isotope natural abundance analyses to identify the organic nutrient source ofE.aphyllumfrom Central Norway. These data for orchid shoot tissues, in comparison to accompanying autotrophic plants, document C and N flow from ectomycorrhizal fungi to the orchid. DNA data from fungal pelotons in the orchid root cortex confirm the presence ofInocybeandHebeloma, which are both fungi that form ectomycorrhizas. The enrichment factors for13C and15N ofE. aphyllumare used to calculate a new overall average enrichment factor for mycoheterotrophic plants living in association with ectomycorrhizal fungi (ε13C ± 1 SD of 7.2 ± 1.6‰ and ε15N ± 1 SD of 12.8 ± 3.9‰). These can be used to estimate the fungal contribution to organic nutrient uptake by partially mycoheterotrophic plants where fully mycoheterotrophic plants are lacking. N concentrations in orchid tissue were unusually high and significantly higher than in accompanying autotrophic leaf samples. This may be caused by N gain ofE.aphyllumfrom obligate ectomycorrhizal fungi. We show thatE. aphyllumis an epiparasitic mycoheterotrophic orchid that depends on ectomycorrhizalInocybeandHebelomato obtain C and N through a tripartite system linking mycoheterotrophic plants through fungi with forest trees.
