The characteristic leaf symptoms are a smaller number of leaf lobes and a decrease in the number of teeth on the serrated edge of the leaves. The flowers also show symptoms, with the buds being less hairy than normal and, in a severe form of the disease present in Russia and Scandinavia, the sepals appearing to be doubled in number to ten.

Soon after the leaves open in the spring, the galls are yellow and turn red by the early summer. Leaves can also be crinkled, with a colony of yellow-greenish aphids living in the hairy depressions on the underside of the leaves. Cultivars of red currants are preferred. Adults are 1–2 millimetres (0.039–0.079 in) long.
The flowers are produced in early spring at the same time as the leaves emerge, on dangling racemes 3–7 cm (1–3 in) long of 5–30 flowers; each flower is 5–10 millimetres (1 ⁄ 4 – 3 ⁄ 8 in) in diameter, with five red, pink, or white [6] petals. The fruit is a dark purple oval berry about 1 cm (3 ⁄ 8 in) long; it has an insipid ...

Leaf spots on the underside of a leaf on a Ribes species (telial host) On the other hand, the telial host, Ribes, can contract yellowish chlorotic leaf spots, but is otherwise not significantly impacted. The signs of C. ribicola on Ribes, come in the form of the pathogen itself as orange pustules on the underside of the leaf. [2]
