Abstract

DNA was extracted from dried specimens of nine taxa of the Cantharellaceae. Approximately 325 bases near the 5′ end of the nuclear 28S ribosomal gene were sequenced, and the sequences were compared. Sequence analyses demonstrated that Cantharellus and Craterellus should be treated as distinct genera. The phylogeny generated using parsimony suggests that Cantharellus tubaeformis and Pseudocraterellus sinuosus should be considered species of Craterellus. As a result of this study, we recognize the first placement of these two species in Craterellus by Fries and Quélet. A reassessment of the morphological characters used to separate Cantharellus and Craterellus is indicated.
