The uredospores are formed in some species in successive rows and with intervening cells like the aecidiospores, in others singly on slender stalk-like sterigmata, from which they always separate by abscision as they ripen with a view to their dispersion. Their form and structure agree essentially with those of the aecidiospores, Hemileia being the only exception. The teleutospores of most species are formed.
