The mycelium is systemic. Diseased shoots are lanky, unusually lengthened, the leaves are discoloured and somewhat thickened. Only spermogonia and aecia. Spermogonia amphigenous, numerous, yellow, often formed already in autumn; they give off a strong pleasant smell of mock-orange. Aecia hypophyllous, cupulate with a clear margin split into segments; the spore mass inside is yellowish. The spores germinate while forming a basidium.
