| | Genus ''Puccinia'' Pers. is the largest in the order ''Uredinales''. It includes both monoecious and dioecious species, with ''Puccinia allii'' (DC.) Rudolphi affects differet species of genus (''Allium сера, A. sativum, A. porrum, A. fistulosum, A. ursinum, A. atroviolaceum, A. brevidens, A. monadelphum, A. platyspathum''). It occurs everywhere. On the surface of onion’s leaves there appear prolonged, dispersed, sometimes interfluent pustule with urediniospores (fig. 1). | | Genus ''Puccinia'' Pers. is the largest in the order ''Uredinales''.

| − | First they are covered with suberect epidermis, through which one can see masses of yellowish-brown urediniospores (fig. 2). Epidermis breaks and urediniospores flow out on the leaf’s surface (fig. 3, 4, 5). Urediniospores are more or less globular, elliptic or egg-shaped, aculeolate, 18-32 х 18-24 µm (fig. 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16). Teliospores are positioned in black, flat, differently shaped, covered with epidermis acervulus, bicellular, mostly oblongly-clavate or clavate, rounded on top, often dulled, coarctate or truncated, with solid sporoderm, slightly constricted, narrowed to the bottom, smooth, 35-80 х 17-30 µm, brown, on a very short, firm stem, numerous paraphyses are at hand (fig. 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30). | + | First they are covered with suberect epidermis, through which one can see masses of yellowish-brown urediniospores (fig. 2).
