Taxonomy
editThe species was first described from North Carolina in 1942 by American mycologists Alexander H. Smith and Lexemuel Ray Hesler as Hygrophorus canescens. It was transferred to the genus Cuphophyllus by French mycologist Marcel Bon in 1990, at which time it was thought also to occur in northern Europe.[3] As a result of molecular research, based on cladistic analysis of DNA sequences, Cuphophyllus canescens has, however, been found to be restricted to North America.[4]
Similar species
editCuphophyllus atlanticus is very similar, but is said to have a pure gray to bluish gray cap and (microscopically) larger, subglobose spores.[4]
