''Cantharellus lateritius'', commonly known as the smooth chanterelle, is a species of edible fungus in the Cantharellaceae family of mushrooms. A ectomycorrhizal species, it is found in Asia, Africa, and North America. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface (hymenium) of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of ''C. lateritius'' is much smoother. Chemical analysis has revealed the presence of several carotenoid compounds in the fruit bodies. ==Taxonomy==
The species was first described in the scientific literature as ''Thelephora cantharella'' by the American Lewis David de Schweinitz in 1822, based on specimens collected in Ohio.〔 Elias Magnus Fries later transferred it to ''Craterellus'' in his 1838 ''Epicrisis Systematis Mycologici''.〔 In 1856, Miles Joseph Berkeley and Moses Ashley Curtis mentioned the fungus in their analysis of Schweinitz's specimens, but changed the epithet, calling it ''Craterellus lateritius''.〔 The motivation for the name change is unclear; Ronald H. Petersen, in a 1979 publication, suggests that Berkeley "was apparently reluctant to surrender his own name for the organism".〔 Petersen suggests that Berkeley may have foreseen the necessity to avoid giving the species a tautonym (a situation where both the generic name and specific epithet are identical). However, as Petersen indicates, a future publication renders this explanation dubious: in 1873 Berkeley again referred to the species using his chosen name ''Craterellus lateritius'', and indicated a type location (Alabama) different than the one mentioned by Schweinitz.〔 Petersen considers Berkeley's name to be a ''nomen novum'' (new name), not a new species, as Berkeley clearly indicated that he thought ''Craterellus lateritius'' was synonymous with Schweinitz's ''Thelephora cantharella''. Normally in these circumstances, Schweinitz's specimen would be considered the type, but Petersen was unable to locate Schweinitz's original specimen, and thus according to the rules of botanical nomenclature, Berkeley's epithet has precedence as it is the earliest published name that has an associated type specimen.〔 Another synonym is ''Trombetta lateritia'', used by Otto Kuntze in his 1891 ''Revisio Generum Plantarum''.〔 American mycologist Rolf Singer transferred it to the genus ''Cantharellus'' in 1951.〔 The mushroom is commonly known as the "smooth chanterelle".〔 The specific name ''lateritius'' means "bricklike", and refers to the smooth hymenium.〔
