Hexalectris (crested coralroot)[1] is a genus of the family Orchidaceae, comprising 10 known species of fully myco-heterotrophic orchids.[2] These species are found in North America, with the center of diversity in northern Mexico.[3] None of the species are particularly common.[4] Hexalectris spicata has a wide distribution and is likely the most abundant member of the genus, but is nevertheless infrequent throughout its range.[4] Other species are rare, and some, such as H. colemanii, are threatened or endangered.[5] All species that have been studied form associations with ectomycorrhizal fungi that are likely linked to surrounding trees.[6] Many Hexalectris species are found in association with oak trees (Quercus), which are ectomycorrhizal.[7]
