Molecular phylogenetics have been applied to the problem of discriminating between "Craterellus" and "Cantharellus" genera. Results indicate that the presence of a hollow stipe may be a synapomorphy (a trait corresponding to the evolutionary relationship) which reliably identifies "Craterellus" species. "Cr. cornucopioides" appears to be a single polymorphic species, while "Cr. tubaeformis" may be two separate genetic groups separated by geography.
