The authors discuss and illustrate several American collections of Cantharellus that are in one way or another related to species that have previously been reported or described from Wisconsin. These new collections indicate that the potential distribution area of many of these chanterelles may be much larger than generally assumed. Cantharellus deceptivus sp. nov. is described as new cryptic look-alike of C. phasmatis and problems related to the narrow species concept of C. flavus and C. phasmatis are discussed; C. iuventateviridis sp. nov. is described as closest southern relative to C. chicagoensis. Microscopic features of C. chicagoensis and C. flavus are illustrated for the first time. Cantharellus spectaculus is considered a later synonym of C. persicinus on morphological criteria.
