only the uredinia are known. They are hypophyllous, pustulate, covered by the epidermis, leaving a central pore. Spores clublike, remotely echinulate. The uredinia ripen in late autumn and winter, releasing a white mass of spores, especially in damp weather. Telia on brown patches of the overwintered fronds. The spores are formed intracellularly in the epidermis, in groups of 1-5.
