In some cases the fungi collected from a single host may be referred — according to the size of teliospores and other morphological features — to almost any species of Melsmipsora on Euphorbia. Miiller, Klebahn, Jacky, and others concluded that the biological specialization does not justify the establishment of independent species. The morphological differences mentioned, in conjunction with the fungal specialization and the impossibility of identifying reliably the species described in the literature (herbarium specimens), permit us to consider Melampsora on Euphorbia a genetically collective species. We deemed it expedient to designate as Melampsora euphorbiae (Schub.) Cast, all genetically united forms of Melampsora on species of Euphorbia. Other names such as M. helioscopiae (Pers.) Winter, although given earlier, are less appropriate for they indicate the species of the host plant. A somewhat special place is occupied by M. gelmii Bres., on Euphorbia rapulum, Kar. et Kir,, discovered by us in the USSR and Central 6.
