 The species was originally described by Miles Berkeley and Moses Ashley Curtis in 1859 as Agaricus murrayi , based on collections made in New England . Berkeley and Curtis called it " An extremely pretty species " . Pier Andrea Saccardo transferred the species to Entoloma in 1899 . Synonyms include combinations resulting from generic transfers to Rhodophyllus by Rolf Singer in 1942 , <unk> by R. W. G. Dennis in 1970 , and to Inocephalus by Gordon Rutter and Roy Watling in 1997 . Depending on the authority , these latter three genera are considered either subgenera of Entoloma , or independent genera . In a large @-@ scale molecular phylogenetic analysis of Agaricales species published in 2002 , E. murrayi grouped in a clade together with E. canescens and two <unk> traditionally classified in Inocephalus – E. quadrata and E. lactifluus . The Dictionary of the Fungi ( 10th edition , 2008 ) lumps Inocephalus and Rhodophyllus into Entoloma .
