 Several molecular phylogenetic analyses show that L. deterrimus , L. sanguifluus , Lactarius vinosus and L. fennoscandicus form a group of related species , which might include the North American species L. paradoxus and L. miniatosporus . Although L. deliciosus var. deterrimus qualifies as synonym for L. deterrimus , the families , which had been characterized in North America as Lactarius deliciosus var. deterrimus , are not closely related with the European types . They also seem not to form a monophyletic group .
