gal: geen waardwisseling. Spermogonia honingkleurig, in dichte kleine groepen. Aecia geel, bekervormig met omgeslagen rand, op vergalde en verkleurde delen van bladeren en bladstelen. Uredinia onderzijdig, lichtbruin, vroeg naakt, dan poederig; sporen vrijwel bolrond, 16-21 x 18-28 µm, met 2 kiemporen. Telia als de uredinia, maar donkerbruin; sporen 2-cellig, kort-ovaal; wand dun, apicaal niet verdikt; kiemporen met een duidelijke papil, die van de onderste cel meestal dichtbij de tussenwand; steel kort, fragiel.

gall: no host plant alternation. Spermogonia honey-coloured, in dense small groups. Aecia yellow, cupulate with recurved margin, on galled and discoloured parts of leaves and petioles. Uredinia hypophylous, light brown, soon naked, then pulverulent; spores ± globular, 16-21 x 18-28 µm, with 2 germination pores. Telia like the uredinia, but dark brown; sporen 2-celled, short-oval; wall thin, apically not thickened; germination pores with a distinct papilla, the one of the lower cell generally close to the separation wall; pedicel short, fragile.
