'''Heterokaryosis''' (from the Greek ''heteros'', meaning ''other'' and ''karyon'', meaning ''kernel'') is a term used in [[mycology]] meaning to have two or more genetically different nuclei within the same [[mycelium]] of a fungus.
Many fungi (notably the [[mycorrhiza|arbuscular mycorrhizal fungi]]) exhibit this phenomenon. The nuclei within the same mycelium may differ from one another either through the accumulation of [[mutation]]s or through the fusion of genetically distinct fungal [[hyphae]]. This can lead to individuals that have different nuclei in different parts of their mycelium. In this case, the notion of ''individual'' itself becomes vague since the rule of one genome = one individual does not apply any more.
