[A]n ectomycorrhizal homobasidiomycete genus, with terricolous, fleshy, solid, and long-lived but not perennial gymnocarpic sporocarps. The pileus has a sterile top, which distinguishes it from the Clavariaceae. The hymenium is either smooth or folded, with ridges on the stem and pileus. The gill-like ridges differ from true gills of the order Agaricales. The Cantharellus hymenium thickens as new basidia develop over the layer of older ones. By contrast, in the Agaricales the basidia form a monolayer. Cantharellus basidia are stichic and long, bearing long curved sterigmata. Spores are smooth, white or yellow, and of variable size. The number of spores per basidium varies between two and eight within the same carpophore. The haploid chromosome number in C. cibarius Fr. is 2. No cystidia are present. Hyphae are monomitic and clamp connections are present. The species studied so far within Cantharellus sensu Feibelman and others (1997) have large internal transcriber spacer (ITS) sequences, 1400 to 1600 base pairs, and a sequence in the beginning of ITS1, which is unique to the genus Cantharellus sensu Feibelman and others (1997).
