 "Camarophyllopsis" was circumscribed by Czech mycologist Josef Herink in 1958, with "Hygrophorus schulzeri" as the type and only species.Roger Heim had the year previously treated this group of species under the name "Hodophilus", but this was invalid because he did not include a Latin diagnosis for the genus, as was required by the rules of botanical nomenclature at the time.Rolf Singer published "Hygrotrama" in March 1959 (with type species "Hygrotrama dennisianum"), and Heim later (1966) published the name "Hodophilus" validly (type species "H. foetens").
