 It was termed in order to describe the poisonous green-spored "C. molybdites" which shared many characteristics of the mushrooms within the genus "Lepiota" but lacked the all important white spores.The name derives from Greek "Chloro" meaning green and "phyllo" meaning leaf (or gill in this case).It remained as a monotypic genus until recently when modern DNA analyses concluded that many of the mushrooms contained in the genus "Macrolepiota" actually had more in common genetically with the "Chlorophyllum molybdites" than with the other members of the "Macrolepiota".
