 This means that "Camarophyllus" sensu stricto is a synonym of "Hygrophorus", since "A. camarophyllus" is a "Hygrophorus" species ("Hygrophorus camarophyllus").This is now accepted by all standard authorities.Singer (1951), however, proposed "Agaricus pratensis" (= "Cuphophyllus pratensis") as the type species of "Camarophyllus", which means that "Camarophyllus" "sensu" Singer is a synonym of "Cuphophyllus".
